上海某地下厂污水处理工艺设计和运行效果

Process Design and Operation Performance of a Underground Wastewater Treatment Plant in Shanghai

该污水处理厂的建设对服务区域的经济社会发展和苏州河水环境的保护具有重要的意义。本文介绍了该污水厂的主要工艺设计参数,分析了该污水厂的设计特点和实际运行效果,结果表明:该厂处理水量稳定达到设计水量,进水有机物和SS浓度达到设计进水水质,出水稳定达到一级A排放标准,氨氮和总磷达到地表水IV类标准,深度处理单元对TP的去除效果突出,污泥处理后实际含水率约30%,可满足外运处置的要求。

The construction of this wastewater treatment plant is of great significance to the development of the business district and the protection of Suzhou river water environment.This paper introduced the main design parameters of this wastewater treatment plant,and analyzed its design features and actual operation results.The results showed that the treated water volume of this wastewater treatment plant reached the design water quality,the effluent reached the first-class A discharge standard,ammonia nitrogen and total phosphorus reached the surface water IV standard,and the actual water content after sludge treatment is more or less 30%,which meet the requirement of sludge disposal outside the plant.
