摘要
小型地下式污水处理厂在工业园区污水处理中应用越来越多。以某光电产业园区污水厂为例,该厂建设规模为3万m^3/d,全地下式,采用高效沉淀+A^2/O+MBR工艺,出水执行《城镇污水处理厂污染物排放标准》(GB 18918-2002)一级A标准。介绍了该厂污水、污泥处理工艺和主要处理构筑物的设计参数,并总结工程特点。
The small-sized underground wastewater treatment plant(WWTP)is used more and more in the sewage treatment of industry zone.Taking a WWTP of opto-electronics zone as an example,the construction scale of this WWTP is 30000 m^3/d,is fully underground and uses the efficient sedimentation+A^2/O+MBR technology.Its effluent executes the Level A standard of Municipal Wastewater Treatment Plant Pollutant Discharge Standard(GB18918-2002).This paper introduces the design parameters of sewage and sludge treatment technologies,and the main treatment structures of this WWTP,and summarizes the engineering characteristics.
