摘　　要：广东某污水处理厂工程总规模为2.5万m^(3)/d,分阶段实施,一期设计处理规模为0.4万m^(3)/d,总变化系数2,远期达到2.5万m^(3)/d。土建一期按2.5万m^(3)/d建设,设备按照0.4 m^(3)/d建设。本工程采用调节池→初沉池→水解酸化池→A/A/O池→二沉池→高效沉淀池→纤维转盘滤池→消毒接触池的主体处理工艺,经处理后的水质应达到《城镇污水处理厂污染物排放标准》(GB18918-2002)一级A排放标准和广东省《水污染物排放限值》(DB44/26-2001)第二时段一级标准较严值。The total scale of a sewage treatment plant project in Guangdong is 25000 m^(3)/d,which will be implemented in stages.The design treatment scale for the first phase is 4000 m^(3)/d,with a total coefficient of change of 2.In the long term,it will reach 25000 m^(3)/d.The first phase of civil engineering was constructed at a rate of 25000 m^(3)/d,and the equipment was constructed at a rate of 4000 m^(3)/d.This project adopted the main treatment process of regulating tank→primary sedimentation tank→hydrolysis acidification tank→A/A/O tank→secondary sedimentation tank→high-efficiency sedimentation tank→fiber rotary disc filter tank→disinfection contact tank.The treated water quality should meet the Class A discharge standard of the Pollutant Discharge Standard for Urban Sewage Treatment Plants(GB18918-2002)and the stricter Class I standard of the Water Pollutant Discharge Limits(DB44/26-2001)in Guangdong province during the second period.
