摘要
某城市某区域生活污水处理厂设计规模为50000 m^3/d。针对污水特点及排放要求,该工程处理工艺采用:A^2/O+高效沉淀池+滤布滤池工艺,污泥处理采用机械浓缩脱水工艺。本文详细介绍了进、出水水质及工艺流程、主要设计参数,出水水质最终满足《城镇污水处理厂污染物排放标准》(GB 18918-2002)中的一级A标准,相关经验可供类似工程参考借鉴。
The design scale of a domestic sewage treatment plant in a certain city is 50000 m^3/d.According to the characteristics of sewage and discharge requirements,the treatment process of the project adopts A^2/O,high-efficiency sedimentation tank and filter cloth filter process,and sludge treatment adopts mechanical concentration dehydration process.This paper introduces in detail the water quality and process flow and main design parameters of the inlet and outlet waters.The effluent quality finally meets the Grade A standard in the Pollutant Discharge Standards for Urban Sewage Treatment Plants(GB18918-2002).This relevant experience can be used for reference in similar projects.
