城市黑臭水体治理中的清污、雨污分流方案研究——以南方某市为例

Study on Clean, Rain and Waste Water Separation Scheme in UrbanBlack and Odorous Water Treatment--Case Study of a City in South China

在我国南方城市,由于水网密布,地下水位较高,其管网问题更加复杂。本文以南方某城市为例,通过详细调查,识别出清污混合、雨污混接是导致黑臭水体形成的重要因素。针对上述问题,提出了管道水质检测,网格化排查,管道流量沿程追溯相结合的清污混合溯源方法。详细列举了单位社区、市政道路存在的各种雨污混接问题,并逐项制定解决方案。工程实施后取得了良好效果。

In South China,due to the dense river system and high groundwater level,the urban drainage problems are more complex.Through detailed investigation in a city of South China,this paper identifies that the mixing between clean and waste water as well as the mixing of rain and waste water pipes are the important factors leading to urban water black and odorous problems.In order to solve the problems,this paper puts forward drainage water quality detection,drainage grid investigation and pipeline flow tracing method to locate clean and waste water combining sources,and lists detailed and various appearances of rain and waste water pipelines mixing in communities and urban roads.In this paper,solutions are formulated one by one,and good results have been achieved after the implementation of the project.
