最简单的水体污染的定义是水体的一些污染物（S）改变任何水体的物理，生物，二手化学条件使这个水中有害对环境和周边生态系统的任何污染。直接或间接地排入水体 中国水污染会发生过多的污染物一次（大多在不同废物的形式）。水污染不只是造成巨大的环境破坏又是亡和疾病的全球领先的原因负责超过14,000人每天在发展中国家亡，大部分是。 很多人不知道，水的污染是世界几乎所有地区严重的问题，而不是只在第三世界国家像一些选择相信。事实上，很多专家会告诉你，现实比共同的信仰完全不同，而且实际上水污染问题已经失控。 中国的水污染问题，在大多数情况下与化学试剂的粗心处理连接，通过倾倒工业引入到我们的水毒素和农田径流。所有这些因素使得我们的水不安全喝。 中国例如，被广泛用于消毒我们的水被许多人认为是致癌物质，因此，一个主要的健康问题该显著世界范围内造成了氯上升癌症发病率的。 基本上氯存在于每杯水中，我们从我们的自来水画，尽管一些研究已经证实，氯确实是癌症的危险因素之一我们不能因为从我们去除水中的氯，我们将打开大门，许多水传播疾病将杀数以百万计的世界各地的人们离不开它。 中国那么如何保护自己免受水污染？最好的办法提供给我们的是安装一个多层次的家庭水过滤系统在您的家。最好的办法是多介质模块系统有一个活性碳颗粒过滤器，亚微米过滤器，离子交换。该系统能够防止了所有我们的水存在有害污染物的99 One of the most serious problems is the serious pollution of air, water and soil The polluted water causes diseases and deathTo protect the environment, governments of many countries have done a lot Therefore, governments are playing the most important role in the environmental protection today First, it should let people fully realize the importance of environmental protection through education Finally, those who destroy the environment intentionally should be severely punished保护环境目前环保还存在着许多问题。最严重的问题就是空气、水和土壤的严重污染。污染的空气对人类的健康十分有害。污染的水引起疼病，造成死亡。更有甚者，随着现代社会的迅速扩建，植被大大的减少。为了保护环境，各国政府做了大量的工作。采用了立法措施控制大气污染，保护森林资源和海洋资源，制止任何环境污染。因此，在当今的环保中政府起着最重要的作用。我的看法是，为了保护环境，政府应当采取更具体的措施。首先，应当通过教育的方法使人们充分謒到环境保护的重要性。第二，应更加努力把计划生育政策付诸实施，因为人口多就意味着污染严重。最后，要严惩那些故意破坏环境者。使他们破坏环境就是毁灭人类自己。
1、水污染会使中国水资源质量不断下降，水环境持续恶化，由于污染所导致的缺水和事故不断发生，不仅使工厂停产、农业减产甚至绝收，而且造成了不良的社会影响和较大的经济损失，严重地威胁了社会的可持续发展，威胁了人类的生存。
Water pollution will cause the quality of China's water resources to continue to decline, the water environment will continue to deteriorate
It willseriously threaten the sustainable development of society and threatens the survival of mankind
According to surveys by authoritative institutions in the world, in developing countries, 80% of all kinds of diseases are spread by drinking unsanitary water Therefore, water pollution is called "The world's number one killer
The pollution of water affects people's lives and destroys ecology
4、水污染会危害人们的身体健康，饮用被污染过的水污染物会进入到身体里，导致人急性或使慢性的中毒，还会引发多种传染病等，对人体的危害较大。
water pollution will endanger people's health, drinking contaminated water pollutants will enter the body, leading to acute or chronic poisoning, but also cause a variety of infectious diseases, etc
5、水污染不利于农业的发展。水污染会导致我们种植的农作物减产、品质降低，污水灌溉降低土壤的质量。
Water pollution is not conducive to the development of agriculture
扩展资料
多年来，中国水资源质量不断下降，水环境持续恶化，由于污染所导致的缺水和事故不断发生，不仅使工厂停产、农业减产甚至绝收，而且造成了不良的社会影响和较大的经济损失，严重地威胁了社会的可持续发展，威胁了人类的生存。
中国七大水系的污染程度以污染程度大小进行排序，其结果为:辽河、海河、淮河、黄河、松花江、长江，其中，辽河、海河、淮河污染最重。
