Dear Sarah,

I am terribly sorry to tell you that I am unable to attend your birthday

part next Thursday evening. That is owing to the fact that my younger brother

suddenly fell ill and was taken to a hospital this morning. I have to go there

immediately and take care of him. As told by the doctor in charge, it will take

around five days for him to recover and I have asked my boss for a leave.

I really regret that I cannot go to celebrate your birthday personally and

would miss the perfect chance of enjoying myself with all our old friends. I

have chosen a small gift for you and will send it to you tomorrow to show my

best wishes. Besides, please give my regards to our friends when you meet them

The campus environment is becoming more and more serious, the plastic bags are strewn all over the floor, the scraps of paper are flying, and there is a smell of smoke from time to time.

Therefore, in order to make the campus more beautiful and clean, as long as we work together, we will take care of the plants and trees as they do to our lives. Dont litter the peel and plastic bags. We want to be like a cleaning worker, and when the plastic bags and the scraps of paper are thrown on the ground, whether you throw it or not, you must always pick it up. In school, it is hard to prevent spitting or snot.

The students put out their hands, let us protect the campus together, let those bad phenomena which harm the classmate bad, the harm to the classmate disappear forever! In this way, the sunshine will be brighter tomorrow, the air will be clearer and the campus will be more beautiful and tidy.

The environment is the harbor of the mind; The artist said: "the environment is the source of inspiration. The military says that the environment is the key to success. Educationalists say that the environment is the cradle of creation. Students say: the environment is a necessary condition for our study. Each of us is the master of this campus and has the duty and responsibility to safeguard the campus environment.

The quality of campus environment directly affects the work, study and life of teachers and students. Nowadays, on our campus, we still have the food packaging bags, scraps of paper, and beverage bottles scattered by our classmates. Every time the wind blows, the rubbish will dance on our campus, all of which is out of proportion to the green environment on our campus. "Campus is my home, cherish the people", believe no teacher, the classmate hope to learn in the environment that rubbish everywhere, life.

So from now on, we should take good care of the campus environment and conscientiously maintain the cleanliness and hygiene of the campus. Develop good hygienic habits, and make the rubbish into bins and bagged garbage. Pick up scraps from the ground at any time, throw them into the trash, make sure the ground is clean, and remind and stop littering. Take good care of the campus public goods, not messy painting and so on.

Remember, the first day when I walk into our campus, I found the campus everywhere "care for the environment, everyone duty" signs, see the signs, I feel very happy, because I know, I live in the campus must be a beautiful environment, suitable for the place where we grow. However, the reality is very cruel and in our campus, always can see some disharmonious white trash, always can see the ground of debris-brick, I sad for it.

Today, who is destroying our campus environment, who has taken away the beauty of the campus? Everyone should know that it is us who destroy the campus environment. There are a lot of students who learn to "paint" on a clean wall. These bad behaviour, has attracted many students, however, we are always at the bottom of the moan, hardly anyone can bent down and picked up the ground of debris-brick; Few people can voluntarily erase the footprints on the wall. Is because of this, after the morning cleaning the health, in the afternoon, the campus is no longer beautiful, so today, here I take this opportunity to call for everyone: civilized and harmonious environment depends on everybody, let each of us to maintain the environment consciously, dont scribble on the wall, dont litter and pick up the waste paper.

I believe that as long as we everyone involved in protecting the environment, our campus will be bright blue sky, the wall of our campus more white, our campus will be beautiful and clean.

Protection of the Environment

Once man did not have to think about the protection of his environment. There were few people on the earth, and natural resources seemed to be unlimited.

Today things are different. The world has become too crowded. We are using up our natural resources,and polluting our environment with dangerous chemicals. If we continue to do this, human life on earth will not survive.

We realize that if too many fish are taken from the sea, there will soon be none left. Yet,with modern fishing methods, more and more fish are caught.We know that if too many trees are cut down, forests will disappear. Yet, we continue to use powerful machines to cut down more and more trees. We see that if rivers are polluted with waste products, we will die. Yet, waste products are

still put into rivers.

We know that if the population continues to rise at the present rate, in a few years, there wont be enough food.What can we do to solve these problems?

If we eat more vegetables and less meat, there will be more food available. Land for crops feeds five times more people than land where animals are kept.

Our natural resources will last longer if we learn to recycie them.

The world population will not rise so quickly if people use modern methods of birth control.

Finally, if we educate people to think about the problems we shall have a better and cleaner planet in the future.

[保护环境的英语作文精选

Stepping into the new century, environment pollution has become more

serious than ever since. There are different kinds of pollution. Such as, water

pollution, air pollution and noise pollution and so on. It seems that we live on

a planet which is full of pollution. Where all these pollution comes from? To a

large extend, the environmental destruction is the heavy price that we pay for

the rapid development of economy and the growing population. In order to have

more fuel, people cut down trees and dig more corals. But the growing needs for

energy are hardly to meet. Countless private cars on the street, the gas

stations are short of gasoline, even the government has raise the price so many

times in order to control the needs of gasoline, but it’s still not working.

Overusing the natural resources has already affected the ecological balance.

However, the factories still release the toxic air into the sky and the polluted

water into the rivers. People still lack of the conscious of protecting the

environment. I think it’s time for all of us to do something.

The government should put forward some more strict laws to prevent the

environment from being further polluted. And they should let people know more

about the importance of environment protection. And we should find the balance

between the economic growth and environmental protection. Plant more trees in

the deserts and stop cutting down the forest. Forbid the factories to pour the

waste water into the rivers directly. Encourage people to use public

transportations to work. Both government and ordinary people should join hands

together to make our home clean and fresh again. Only in this way, our earth

could be a better place to live in.

We cant live without water, but now the water was polluted.It is the biggest problem.It influences our daily life.So we should find a way to solve this problem.Water is important resources.In our daily life, we often leave the tap on after cleaning hands.Sometimes we often drop litter in the river.So the water was polluted by us.I think we could use a bottle of water two or three times.We have to turn off the tap after cleaning hands.

Lets try to form a good habit and save things around us.Lets do it from now on!

Water is very important to us.We cant live without water.But the drinking water is less and less.Because we waste a lot of water in our daily life.And some of us often throw rubbish into the rivers.So the rivers are polluted seriously.

Its our duty to save water, we must do something to save water.For example, we shouldnt pour waste water into the rivers and we should pick up litter around us.

If we dont save water, the last drop of water will be our tear.

Fish cant live without water.Plants cant live without water.People cant live without water, either.As you can see, the water is very important to us.But now drinking water is less and less.The water was polluted seriously.

So we would act quickly in order to save the water, But what must we do now? I think we can plant trees, clean the banks of the river, water the plants by using used water.Turn off the shower while we are washing hair.And we shouldnt drop litter into the river and so on.

Its our duty to try our best to protect and save water.And dont forget that if we dont save water, the last drop of water will be our tear.;

If we dont save water, the last drop of water will be our tear.What a frightful announcement!

Water is very important for people, animals and plants.Water is needed to many things in daily life, like taking a shower, drinking, washing clothes, making meals and so on.We cant live without water.But now water has become less and less because people waste water and pollute water.If we continue to do things like this, we shall destroy ourselves.So we should take action to improve the environment quickly.We shouldnt throw rubbish into the rivers.We should pay attention to environmental protection.We can use less water when we wash something.In a word, we should save water.

Humans have only one earth. He is the cradle of life, is the homeland of all mankind. However, the environmental pollution and ecological destruction have on human social and economic development and peoples normal life constitutes the real threat. Take good care of the environment, advocate civilization, is the human moral and responsibility.

We want to clean the earth, eager to healthy earth, eager to the homes of environmental protection, eager to green, health, community health... Let us use love to pay attention to changes in the environment, with passion to spread the idea of environmental protection, with actions to shoulder the important task of environmental protection. Starts from me, start from now, intravenous drip minor matter, starts from the side the environmental commitment into action.

Remember, protect the earth, is to protect ourselves.

人类只有一个地球。他是生命的摇篮，是人类共有的家园。然而，环境污染与生态破坏已经对人类的社会经济发展和人们的正常生活构成了现实威胁。爱护环境，崇尚文明，无疑是人类自身的道义和责任。

我们渴望干净的地球，渴望健康的地球，渴望环保的家园，渴望绿色，健康，卫生的社区……让我们用爱心去关注环境的变化，用热情去传播环保的观念，用行动肩负起环保的重任。从我做起，从现在做起，从身边的点滴小事做起，把环保承诺变为实际行动。

记住，保护地球，就是保护我们自己。

Environment for us, it is very important, its like a big umbrella, zhefengdangyu for us to protect our homes, if left the magic umbrella, that our home will be like the Sahara desert, a lifeless, desolate. So I want to give meaning to the world, let us together to protect the environment!

Now our side, however, the environment is worsening, I once saw a man on the side of the road just lost a piece of paper, I was very sad, think if everyone throw a piece of paper, then the world will be what are the consequences? Is terrible, and the world will become a white tips, more think more terrible, I quickly pick up the pieces of paper, thrown into the garbage can. At another time, I saw on TV a report about the environment: fujian on the other side of the river water turbidity is not clear, the fish died in the river, floating in the river every fish mouth blowing, the river still waving white trash, have small bags, candy. The scene is really horrible. Improvement in living standards of people, and their environmental protection consciousness is on the decline. And those without morality of tree, they may have thought about the benefits of trees give us? Tree for we pay so much! So many trees for our block of sandstorm and fearful tornado, these trees should have quietly thoroughly self-reflection, if there are no trees, our living environment is what? Visible at the moment we bad environment, also issued a warning to us, remind us take good care of the environment is urgently needed! I think good care environment, everyone duty, so we have to start from now, start from the side, do not spit everywhere, dont throw the paper scraps, less use notebook, can when checking the finished with the book, read the newspapers to practice calligraphy. To protect the environment as the most important work, set up environmental protection consciousness, the guardian to protect the environment.

"To protect the environment, everyone duty." I am going to put this sentence in mind, take this sentence as a seed, I will use attentive to watering it, let it grow, let the "care for the environment, everyone duty" this sentence. I believe that as long as we work together, in the near future, our environment will be getting better and better.

环境对于我们来说，是非常重要的，它就像一把大伞，为我们遮风挡雨保护我们的家园，如果离开了这把神奇的伞，那我们的家园就会像撒哈拉大沙漠一样，一片死气沉沉，荒无人烟。所以我要向全球发出意示，让我们一起保护环境吧!

然而现在我们身边，环境越来越恶化，有一次我看见一个大人在路边随便丢了一张纸，我非常伤心，心想如果每个人都丢一张废纸，那么这个世界会是什么后果呢?真是太可怕了，整个世界就会变成白色的垃圾站，越想越可怕，我急忙把这个纸片捡起来，丢进垃圾桶里。还有一次，我在电视上看见一篇有关环境的报道：福建那边的江水浑浊不清，江里的鱼都死了，浮在了江面，每条鱼的嘴里都吐着白沫，江边还飘着白色垃圾，有小食品袋，糖果皮。这一景象真是惨不忍睹。人们的生活水平在提高，自身的环保意识却在下降。还有那些没有道德的伐树者，他们可有想过树给我们带来的好处呢?树为我们人类付出了那么多!那么多树为我们挡住袭来的沙尘暴和可怕的龙卷风，这些伐树者真应该静静的好好的反省一下，如果没有了树，我们的生活环境又是什么样子呢?可见目前我们环境的恶劣，也是在向我们发出了警告，提醒我们爱护环境刻不容缓!我认为爱护环境，人人有责，所以我们要从现在做起，从身边做起，不要随地吐痰，不乱丢纸屑，少用本子，用完的本子可以当验算本，看完的报纸可以练习毛笔字。把保护环境当做最重要的工作做下去，树立环保意识，做环保守护者。

“保护环境，人人有责。”我要把这句话铭记在心，把这句话当作一颗种子，我会用细心去浇灌它，让它茁壮成长，让“爱护环境，人人有责”这句话传递下去。我相信，只要我们齐心协力，在不久的将来，我们周围的环境一定会变得越来越好。

Environmental Pollution

Write a passage with the words and phrases given:

the problem of pollution, cause, artificial substances, release, waste products, industrial production, consumption of goods, bring it under control, agriculture, chemical substancea.

Environmental Pollution

I read a piece of news recently. It says that in Japan marly businessmen ave selling fresh air to customers.and now it is becoming more and more popular. Why? --Fresh air is getting less and less in Japan, and so is it in the U. S. A.

In fact, environmental pollution is a very serious problem the whole world is facing.

it is mainly caused by the waste products released from artificial substances, industrial

production and increased consumption of goods. Bedsides, the use of chemical substances

in agriculture also causes environmental pollution. Look at the sky, you can see that dense smoke is being released from the high and big chimneys; those dirty and poisonous substances are flowing into the rivers that we use for drinking water and millions of tons of waste products are heaping around us.

How to change this condition? More and more countries are trying to work out some effective means to bring it under control, but no great success has been made.

环境污染

最近我读了一则消息说在日本，许多商人向顾客出售新鲜空气，现在这种情况越演越烈，Environmental Pollution-环境污染，四六级写作《Environmental Pollution-环境污染》。为什么呢? 因为在日本新鲜空气越来越少，在美国也是如此。

事实上，环境污染是整个世界正在面临的一个严重问题。这主要是由于人造物质，工业生产过程中所产生的废料以及消费商品的增长造成的。另外，在农业中使用化学物品也造成了环境污染。看看天空，你可以看到浓烟从高大的烟囱中释放出来，这些脏而有毒的物质流入我们赖以饮水的河流，数百万吨废物正堆积在我们周围。

怎样改变这种状况呢？越来越多的国家正在试图拟定出一些有效措施控制环境污染，但至今成效不大。

今天，我们读了很多关于保护环境的小短文。我想起曾经在我身边发生的事情。

记得是去年的暑假，我和爸爸一起去鹅湖边散步，走了一段路，我就一个劲的喊口渴，于是，爸爸就在路边的小店给我买了根冰棍。我边吃边走，一会儿就吃完了，随手把冰棍棒往鹅湖里一扔。爸爸看见了，马上提醒我说;“可可，不能乱扔垃圾噢!如果每个人都像你一样往湖里扔垃圾，这美丽的鹅湖不就变成了垃圾湖了。”我羞愧的说：“知道了，我下次一定不乱扔垃圾。”爸爸微笑着抚摸我的头说：“地球也是我们的家，我们应该保护它，爱护它，让天更蓝，水更清，草更绿。”我调皮的说：“噢，那就是大家一直说的，城市是我家，环境清洁靠大家。我明白了。”让从那以后，我再也不乱扔垃圾了。

我想爱护环境与每个人息息相关，所以要从每个人做起!

Recently, the movies about the old people happen to have the magic and then

come back to their 20 years old time are very popular. The old people do all

kinds of crazy things that they never have the chance to do. These movies tell

people that given another chance, they will do whatever they want to do. I

always hear my parents said when they retired, they could carry out all kinds of

their plans and enjoyed the life. In my opinion, when we are young , we shuold

enjoy our moment and chase our dream. It is a little to carry out the plans when

we are old. Youth is the advantages.

Since I was a little child, I had a dream that I wanted to be a doctor.

When I was little, I watched many TV series and movies about doctors. I thought

they were so great. Therefore, I made up my mind to be a doctor. In my opinion,

doctor is the people who can help patience get out of sickness and pain.I want

to be the person who can help others. However, being a doctor needs so much

professional knowledge and there is a long way to go. So I have to try my best

on my study and go to a good college.

Serious Floods

The Yangzte River is the longest river in China. And its important and helpful to us Chinese. But these days the Yangtze River is bringing us serious floods.

Many villages were destroyed by floods. The floods made hundreds of millions of people lose their homes, relatives and friends. Many children cant go to school as usual .Now the foods have drawn the attention of the whole world. People from abroad have offered their help too. In China, millions of soldiers are busy fighting against the floods. They are working very hard. Many of them have lost their lives in their attempt to save the villagers.

Though we cant help them to fight against floods, we should help them to rebuild their homeland. We can present them our pocketmoney and clothes. I believe most of the people will return to their homeland in the near future.

严重的水灾

长江是中国最长的河流。它对我们中国人十分重要。但现在长江给我们带来了严重的水灾。

许多村庄被洪水冲毁于。洪水使成千上万的人失去了家园，亲戚和朋友。许多孩子不能与平常——样去学校了。现在洪水引起了全球的注意。国外的人也给予了援助。在中国，上百万的战士忙于与洪水搏斗。他们努力工作，许多人在救村民时献出了自己的生命。

尽管我们不能帮助他们抗洪，但我们可以帮他们重建家园。我们可以捐出零花钱和衣服。我相信在不久的将来大多数人会回到家乡。

Ofo has been favored by the public, even the foreign people speak highly of

it. These yellow bikes can be found everywhere, so the people who are in a hurry

can use it and then reached the destination in time. Especially for the

visitors, they can ride these bikes and then have a look at the scenery around.

It can saves them a lot of money and the most important thing is the convenience

it brings. These bikes can be placed any place, even the walking areas. I like

ofo so much. It makes me feel green, because it won’t produce bad air to pollute

the environment.

Cars and Air Pollution

Too many cars have created a lot of serious problems in our world. Besides congestion, accidents and fast fuel consumption, cars are responsible for a good part of air pollution in big cities. All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, causing disease and even death.

One possible solution is to design and develop clean cars and clean fuels. In Shanghai, some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars completely replace the traditional ones. Another solution is to develop modern public transportation systems and restrict the use of private cars. If the price of petrol rises constantly and the public vehicles are efficient and convenient enough, most people will not buy private cars. And the total number of cars in big cities will reduce greatly.

On the whole, the elimination of air pollution needs the collective efforts from the government, the public and the environmentalists.

River Pollution

Chinese people are now face to a serious problem--pollution. And this problem is a little bit different from others--the goverment can not solve it by themselves. We need everyone to protect our environment. But we also know that it is very hard to call everyone to join us to protect the environment. But it seems that they have found the way to let everybody know it. In a report, Anhui Daily called on residents to help protect the river against pollution. I am so glad about it. And i believe that somewhere the pollution must stop.

河流污染

中国人现在面临着一个严重的问题污染。这个问题有点不同，政府不能自己解决。我们需要每个人来保护我们的环境。但我们也知道，很难叫大家加入我们保护环境。但似乎他们已经找到了让每个人都知道的方法。在一份报告中，安徽日报呼吁居民帮助保护河流免受污染。我很高兴。我相信某处的污染必须停止。

我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。以下是小编给大家整理的形势与政策论文：城市水环境的问题探讨的内容，欢迎大家查看。

摘要: 随着经济快速发展，城市生态形势压力也与日俱增，水环境问题已成为制约社会发展的大问题，环保基础设施建设严重落后，城市生活污染物未得到有效控制，工业污染源未得到严格治理，农业污染日益突出，部分河段水质受污染严重，河水发黑发臭，完全失去水质功能。本文主要对城市水环境治理及污染防治对策进行了分析探讨。

关键词：城市规划;水环境质量;污染防治;对策

城市生态环境是城市宜居水平评价和城市经济发展的重要因素。作为城市生态环境的重要组成部分，城市水环境对生态环境的治理和改善有着重要的影响。受传统经济发展理念的影响，我国城市水环境污染情况不容乐观。而且在城市扩建过程中还造成了大量周边湿地的消失，造成了城市生态环境、水环境的进一步恶化。针对这样的情况，我国近年来加大了城市生态环境治理力度。从城市规划与发展的角度出发，恢复城市周边湿地环境、改善城市水环境与生态环境。

一、城市水环境的基本特点

1、城市用水的特点

生活用水和生产用水是城市用水的主要类型，由于城市人员密集、工业化生产程度高，所以，城市用水需要较高的质量、较大的供水量、稳定的供给，这对城市采水、供水和用水来说有着不同于农村的特点。

2、城市用水的依赖性强

城市由于用水量大、供水要求高，所以，单纯依靠城市区域的供给和开采往往难于满足城市发展的需要，因此，大众城市往往需要从城区周边或外地调水来满足城市的用水需要，“引滦入津”、“南水北调”就是这样的举措。

3、城市水环境脆弱

在我国北方，城市生活和生产用水大都在简单处理或未经处理就直接排放到环境之中，在日积月累的大量污染的影响下，城市水环境受到了严重破坏，并且这一现象有蔓延和恶化的趋势，造成水环境的脆弱和生态的破坏，影响城市深入地发展。

4、城市地下水环境恶化

城市地下水环境恶化来源有两个，一是，城市生产和生活中大量污染源渗入地下，造成对地下水资源和水环境的破坏;二是，城市地表硬化导致城市地面下渗量的减少，在大量开采地下水的同时，没有必要的补充，出现水环境的恶化。

二、城市水环境综合治理方法

1、以人为本，科学发展

把维护广大人民群众的根本利益作为第一点，把群众最关心、最直接和现实的水环境保护问题为重点，转变发展观念，重视生态文明建设，加快建设资源节约和环境友好社会，走科学发展道路。

2、优先保护饮用水源

合格的安全饮用水源是人民生活的必需品，水环境治理应突出重点，优先保护饮用水源，确保群众饮水安全。

3、强化节能减排、效益原则

与区县减排工作挂钩，把COD削减量考核指标纳入到区县水环境治理目标体系中，明确各区县污水处理率、污水处理厂运行负荷率等量化指标。切实保障三个达标，即污水处理率必须达标、污水处理厂的运行负荷率必须达标、COD的减排必须达标。合理安排资金，对节能减排效果明显，有一定经济基础，技术条件成熟，符合国家和行业产业政策的项目优先考虑。

4、治本方针

突出截污治污。河道沿线村镇、企业密集，污染来源复杂。为此，河道治理将坚持“先截污、后清淤、先治理、后换水”的原则，周密排查河道沿线污染来源，大力实施清淤、截污、生态护坡、河岸绿化等措施，加强河道水体自净和生态修复功能;在突出截污治理的同时，各区县还将坚持污水处理厂、配套管网同步建设，大力提升现有污水处理厂运行负荷率，妥善解决污水出路，切实提高河道水环境质量。

5、加强协作，落实责任

市水务局于去年成立了河道水环境考核办公室，将清水工程已治理河道纳入考核范围，各区县按照属地管理原则在本辖区内建立水环境管理机构和相关管理机制，有效巩固水环境治理成果。此外，目前市政府已正式批准本市河道水环境实施“河长制”管理意见，即将公布全市主要河道“河长”名单，构建完善的河道水环境管理长效机制，为今后本市水环境由加强治理向强化管理转变打好基础。

三、城市河流水防治和改善技术的应用

1、底泥疏浚和河床微生态系统修复

在河流洪水、蓄洪功能上,底泥疏浚主要体现在河流利用水面变化增加行洪、蓄洪能力。作为沉积物沉积,有的湖泊水的深度可以被调整,从而减少其调节和存储功能。增加城市河湖疏浚河道水容量后,以确保顺利排出这些河流洪水,保障人民群众的生命和财产安全,也避免了洪涝灾害。底泥疏浚是水环境综合整治的一项重要措施,滇池、巢湖、太湖等水环境综合整治已被广泛使用。可见,合理的疏浚清除污染物,对于生态系统的恢复和重建具有非常重要的作用。

2、人工增氧技术

人工增氧技术是基于城市河流水污染后缺氧的现象,人工的向水体中注入空气或氧气,从而加速水体复氧的进程,提高水体的溶解氧水平,恢复和提高在水中好氧微生物的活力,使河流水的污染物净化,从而改善河流的水质。河流氧气一般使用固定和移动站充氧平台两种形式。河道人工增氧技术的应用,能够使得水质不同时期达到消除黑臭、减少水体污染负荷、促进河流生态系统恢复的目的。

3、调水引流水质改善技术

贯穿城市的内河河网水系,因为控制结构的限制,使得河流水不能够连接到外部的水体,造成水处于静止的状态,当天气炎热的时候,溶解在水中的氧气浓度就会降低,容易导致水质变坏。通过改进水域水动力条件,提高水体污染物的稀释能力,增强局部水体的自净能力,许多城市在水资源利用和部署中,通过跨流域调水工程,解决空间分布不均的问题。

4、植物修复技术

对于河道河流自然恢复应采取生态化措施,主要是通过恢复河岸植被、恢复天然湿地,在河岸种植芦苇、浮萍、睡莲、水生植物和其他湿地植物,以提高水体的净化能力。种植水生植物的城市河流水,一方面能够通过植物的根系的吸收,从而降低和遏制富营养化趋势;另一方面通过种植水生植物,可以也起到美化水体环境,提高城市的景观的效果。

5、生物净化技术

生物净化技术是充分利用天然水体自净的功能,采用人工措施,创造更有利的环境有利于微生物的生长和繁殖,并培养出大量的微生物从而增强水体净化能力,以提高纳污水体氧化降解有机物能力的一种净化方法。目前国内外最常用的生物净化技术是曝气技术、生物膜技术与投菌技术。生物净化技术,其成本低,对环境的影响小,能够有效降解污染物,是水体污染处理的最佳选择之一。生物净化技术及产品的开发,特别是分解菌株的培养也将被筛选到河流水污染控制技术之中,是未来城市水污染防治和治理的发展趋势。将具有特殊分解能力的菌种添加到河边,能够将水体中有毒有害物质分解为无毒无害的物质,从而加速有毒物质的分解、转化,不仅可以提高河流的净化能力,而且也实现了河流的生态修复。生物产品的运用将成为人工增氧、底泥疏浚等现有防治技术的有益补充。

四、结束语

综上所述，我国的城市河流和湖泊污染情况是非常严重的,城市河流水有不同程度的富营养化问题。目前,在城市河流污染环境下,需要完善城市管线网络,并建设污水处理厂,具体的水污染防治技术措施有:底泥疏浚、人工增加氧气、引水排水水质改善、植物修复、湿地水净化技术等河流强化净化技术。能够应对不同的城市的污水状况,使得城市河流水污染的情况得到了有效的控制,促进城市河流的健康发展。
