摘　　要：研究了UASB-喷洒式生态滤池组合工艺处理农村生活污水的效果和特点。研究结果表明:该组合工艺对农村生活污水中的COD,TN,TP,SS去除率分别为69.2%~86.5%,56.45%~93.15%,68.59%~86.82%和83.51%~93%,出水透明度很高。对UASB和生态滤池内指示性微生物分析研究发现,UASB池内以厌氧颗粒污泥为主,生态滤池内以钟虫为主以及少量的轮虫和红斑飘体虫。该工艺遵循生态净化原理,投资少、运维成本低廉,适合在广大农村推广应用。The paper investigated purification efficiency and characteristics of UASB-ecological filter for treating rura domestic wastewater. The experimental results indicated that the COD, TN, TP and SS removal rates of wastewater were69.2% ~ 86.5%, 56.45% ~ 93.15%, 68.59% ~ 86.82% and 83.51% ~ 93% by using the UASB-ecological filter, the effluent transparency was good. The indicated microorganisms of UASB-ecological filter was monitored, the anaerobic granular sludge is the main microorganisms forms in the UASB unit, the Vorticellidae, Rotifera and Lepidoptera erythematosus were main protozoons in the ecological filter.
