摘　　要：介绍了降流式厌氧紊动床(DATB)联合人工湿地(CWs)处理生活污水工艺.DATB通过沼气强制循环,使悬浮载体颗粒处于流化状态,当HRT=6 h时,DATB对COD去除率可达70%左右.DATB出水再通过CWs处理,当HRT=6 d时,CWs对污水中的COD进一步降除,同时可对污水中的NH3-N、TP有效去除,从而实现污水资源化.DATB与CWs联合工艺处理生活污水效果好、耗能低,具有显著的生态效益和社会效益,适合农村中、小城镇的污水处理.The technique of Downflow Anaerobic Turbulent Bed and Constructed Wetlands is proposed to treat domestic sewage. In DATB,the supporter is forced by sludge gas to ensure its fluidity. When HRT is 6h in DATB, the removal rate of COD is about 70%, then the effluent from DATI3 is treated by CWs. When HRT is 6d in CWs,the COD in wastewater can be advanced treated,and NH3-N and TP are removed effectively at the same time. They can implement renovation of wastewater. DATB and CWs treatment to domestic sewage have high activity and low energy consumption, and they have prominent ecological and social results,which fit to treat to domestic sewage of rural area and town.
