大冶市水环境污染源调查及防治
|
摘要
为全面了解大冶市水环境污染源情况,分别对大冶市点污染源和面污染源进行调查,采用产排污系数法、间接估算法和源强系数修正法等方法对污染物入河量进行核算。结果表明:大冶市面源污染对水环境造成的危害与点污染源相当,当地生活污水处理率较低,畜禽养殖与农田径流污染未能得到有效控制。针对上述结果提出相应保护水环境的防治措施建议:(1)从严控制面源污染;(2)强化环保基础设施建设;(3)调整产业结构,实施矿业经济转型。
Surveys were conducted on point pollution source and nonpoint pollution source in Daye city,total amount of pollutants into the river was checked with using the method of pollutants producing coefficient,indirect estimation,and correction of source intensity coefficient. The purpose was to understand the situation of pollution source of water environment in Daye City. The results indicated that the harm of nonpoint pollution source was equal to point pollution source approximately. The local sewage treatment rate is low. Livestock breeding and agricultural runoff pollution had not been controlled effectively. The countermeasures of water environmental protection were suggested on the basis of the results. Firstly,the controlling of nonpoint source pollution need to be treated seriously. Secondly,the construction of environmental protection infrastructure need to be strengthen. Finally,to adjust the industrial structure,and realize the mineral economic transition.
