摘要
文章系统介绍了南方某城镇污水处理厂A2/O氧化沟的工艺设计。其设计总规模为1.2万m3/d,采用A2/O氧化沟工艺,污泥采用机械浓缩和脱水。运行一段时间后的结果表明:A2/O氧化沟工艺处理城镇污水出水水质稳定,可达到《城镇污水处理厂污染物排放标准》(GB18918—2002)中的一级B标准。
The paper systematically introduces the design of A2/O Oxidation Ditch in Small Town＇s Sewage Treatment Plant.The scale of its design is 12 000 m3/d,using the A2/O oxidation ditch process,Sludge Treatment for mechanical thickening and dewatering.After running for some time,the results showed that：The application of A2/O Oxidation Ditch technology in urban sewage can make effluent quality more stable and achieve first class（B） of 《Discharge standard of pollutants for municipal wastewater treatment plant》（GB18918-2002）.
