摘要
采用旁路处理为主、原位净化为辅的综合技术措施对南京市城区某河道黑臭水体进行了快速、有效的水质提升,尤其针对项目建设用地不足的问题,设计选用了占地集约型的复合式MBR工艺为核心的旁路处理系统,并因地制宜地将主体设备架设在项目河道上,极大减少了土地资源占用。工程建成后实际运行结果表明:项目河道实现消黑消劣,COD_(cr)、NH_(3)-N、TP均稳定达到地表V类水标准,SS优于一级A排放标准,另外每年能实现100万m3的清水再生。
The combined process with bypass treatment and in-situ purification was used to quickly and efficiently improve the water quality of a black and odorous river in the main city of Nanjing.Especially towards the problem of the lack of land assigned for the project,the core process of the bypass treatment system with the H-MBR technology which has advantages of less space occupation was designed,which aims to reduce land space.The major parts of the bypass treatment system bridged the engineering river by taking measures to adapt to local conditions.The actual operation results after completion of the project showed that the black and odor phenomenon of the engineering river has been eliminated.At the same time,COD_(cr),NH_(3)\|N and TP are stably reach levelⅤof surface water,and SS was superior to the first level A criteria in the discharge standard.Also,it can produce clear water whose capacity was about1×106 m 3every year.
