南京市雨污分流改造经过多年建设施工，基本上从源头上实现雨污分流，避免污水溢流入秦淮河。初期雨水造成的城市非点源污染是受纳水体的重要污染源，在一些实施了分流制排水系统的城市，经过一段时间的运行，周边水体的污染情况改善不是十分明显。白下区雨污分流改造后，为避免初期雨水对内秦淮河污染，以大中桥泵站北截流沟为例，探讨在沿河截流井设提升泵弃流初期雨水，利用现状截流沟蓄水，结合规划改造大中桥泵站新建蓄水池，为今后雨水利用提供条件。

Rain sewage diversion reconstruction project in Nanjing has been constructed for several years, basically realize the rain sewage diversion from the source, avoid sewage discharge into the Qinhuai Rriver.The initial rainwater caused by urban non-point source pollution is one of the important sources of pollution receiving waters. The water quality of some cities that adopts a separate system drainage system did not record significant improvement after a certain period of running .In order to avoid the pollution of the initial rainwater in the Qinhuai River , this paper takes the north ditch pumping station as an example to discusses in the intercepting well a lift pump split flow rainwater interception ditch.Combined with planning and reconstruction of Dazhongqiao pumping station.Build the new reservoir, rainwater utilization to provide conditions for the future.
