城市水环境治理的点源控制及截污技术

Point Source Control and Pollution Interception Technology for Urban Water Environment Treatment

要有效地推动生态文明建设,减轻水污染所造成的一系列问题,必须加强源头治理,积极实施截污技术,以保障人民的生命健康。从源头和终端两方面进行分析,提出雨污分流系统的改造、雨污混接、错接管道的改造、城市初期雨水收集和处理的源头污染防治、污水直排管道和汇流管道的末端治理。最后,提出加强对废水处理的控制对策,为进一步优化废水治理提供依据。

To effectively promote the construction of ecological civilization and alleviate a series of problems caused by water pollution,it is necessary to strengthen source control and actively implement pollution interception technology so as to guarantee the life and health of the people.This paper analyses the source and the terminal,and puts forward the retrofit of rainwater and sewage diversion system,the mixed connection of rainwater and sewage,the retrofit of staggered pipeline,the prevention and control of pollution at the source of rainwater collection and treatment in the early city,and the end treatment of sewage direct discharge pipeline and confluence pipeline.Finally,the control strategies for wastewater treatment are put forward to provide basis for further optimization of wastewater treatment.
