Production caused by human activities,water body pollution.Industrial water pollution is the most serious cause.If industrial wastewater containing pollutants it more complex components,not only in water purification difficult,but also more difficult to deal with.Industrial wastewater,industrial pollution is the most important cause of water pollution is the cause.It accounted for the bulk of industrial emissions of pollutants.Pollutants in the industrial wastewater plant variety and diversity because,even similar factories,production processes,they do not contain the quality and quantity of pollutants.In addition to the industrial wastewater discharged directly into water bodies from pollution,solid waste and emissions will pollution to the water body......First of all agricultural pollution is due to land reclamation projects farming land surface or loose in the soil and topography,rainfall is not stable,a natural water flows,increased water suspended objects.Another important reason is that in recent years,pesticides,fertilizers usage growing,and the use of pesticides and chemical fertilizers or absorb only a small amount,the vast majority of the remaining residue in the soil and floating in the atmosphere,through rain,through the dirt surface runoff into surface water and infiltration of surface water forming pollution.For the urban population is concentrated in urban pollution,urban sewage,garbage and water pollution caused by emissions from.Urban pollution to the water body pollution mainly sewage,it is the daily life of a sewage cooks,including the kitchen,wash room,bathroom and toilet discharge of sewage.Urban areas of the world only a year from industrial waste water and living up to 500 kilometers on,and each several times and even a few drops of sewage pollution will be 10 times the water body.
For sewage main measures are :1 :financial,administrative,legal safeguards (1) financial support is essential Obviously,financial support is one of the important conditions for pollution control,no funds all management measures can not be implemented.(2) government support for urban water pollution control is a wide range,not only involving residents,but also relates to field personnel,involving troops system involving minorities,but also involves the interests of the right holder.Therefore,water sector,the problem could not be solved alone,even coupled with the environmental sector,the forces remain unable to pale.Needs strong government support,the city government also needs the support of the central government.Without a strong government support,many of the mandatory measures will be difficult to work.(3) pollution control laws and regulations is,the common law requires compliance with the criteria and should develop local laws to protect the urban water environment for water management law,according to the law,which will be easier to do something.
人类生产活动造成的水体污染中.工业引起的水体污染最严重.如工业废水,它含污染物多,成分复杂,不仅在水中不易净化,而且处理也比较困难.
工业废水,是工业污染引起水体污染的最重要的原因.它占工业排出的污染物的大部分.工业废水所含的污染物因工厂种类不同而千差万别,即使是同类工厂,生产过程不同,其所含污染物的质和量也不一样.工业除了排出的废水直接注入水体引起污染外,固体废物和废气也会污染水体.
农业污染首先是由于耕作或开荒使土地表面疏松,在土壤和地形还未稳定时降雨,大量泥沙流入水中,增加水中的悬浮物.
还有一个重要原因是近年来农药、化肥的使用量日益增多,而使用的农药和化肥只有少量附着或被吸收,其余绝大部分残留在土壤和漂浮在大气中,通过降雨,经过地表径流的冲刷进入地表水和渗入地表水形成污染.
城市污染源是因城市人口集中,城市生活污水、垃圾和废气引起水体污染造成的.城市污染源对水体的污染主要是生活污水,它是人们日常生活中产生的各种污水的混合液,其中包括厨房、洗涤房、浴室和厕所排出的污水.
世界上仅城市地区一年排出的工业和生活废水就多达500立方公里,而每一滴污水将污染数倍乃至数十倍的水体.
对于污水采取的措施主要有：
1：资金、行政、法律保障措施
（1） 资金支持是必不可少的条件
显然,资金支持是污染治理重要的条件之一,没有资金,一切治理措施就无法实施.
（2） 政府的支持是后盾
城市水系污染治理涉及面很广,不但涉及到居民,还涉及到外地人员,涉及到部队系统,涉及到少数民族,也会涉及到权利持有者的利益.因此,单靠水利部门是无法解决问题的,即使再加上环保部门,力量依然是苍白无力的.需要市政府的强力支持,市政府也需要中央政府的支持.没有一个强大政府的支持,许多强制性措施就难以行得通.
（3）污染治理需要法制
法律法规是人们共同遵守的准绳,应制定保护城市水环境的地方性法律,让水系管理部门有法可依,依法行政,这样一些事情做起来会容易一些.
