摘　　要：广东省某污水处理厂规模为5×10^(4) m^(3)/d,采用改良AAO+微絮凝+纤维转盘滤池工艺,建设型式为半地下式。景观上盖的外观,综合楼、变配电间与主厂房的合理分置以及内部构筑物的高集约化组合设计解决了项目紧邻居住区、用地分散且面积严重不足的工程难点。运行结果表明,出水水质稳定优于《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准和广东省地方标准《水污染物排放限值》(DB 44/26—2001)第二时段一级标准中的较严值。该项目厂界环境与周边协调,污水单位投资3334元/m^(3),吨水运行可变成本0.57元/m^(3),经济性良好。The process of a semi‑underground wastewater treatment plant(WWTP)with scale of 5×10^(4) m^(3)/d in Guangdong Province consists of modified AAO,micro‑flocculation and fiber turntable filter.The setting of landscape cover,the reasonable distribution of comprehensive building,electric distribution room and the main factory building,and the highly intensive combined design of the internal structures solved the difficulties in adjacent to the residential area,scattered land and serious shortage of footprint area.The operational results show that the effluent quality is better than the stricter values of the first level A limit specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002)and the first level limit during the second period specified in the Guangdong local standard of Discharge Limits of Water Pollutants(DB 44/26-2001).The boundary environment of the plant is coordinated with the surrounding area.The wastewater unit investment is 3334 yuan/m^(3),and the variable cost is 0.57 yuan/m^(3),indicating that good economic benefit is obtained.
