摘　　要：人工湿地具有氮磷去除能力强、维护管理耗费低等优势,使其成为解决我国农村水污染问题的理想工艺,然而人工湿地普遍存在的堵塞问题阻碍了该技术的广泛推广。采用一种基于粒料砌块的防堵塞人工湿地处理广东农村生活污水,结果显示,人工湿地在短期及长期运行阶段内均可发挥较好的氨氮(NH4+-N)、总磷(TP)与化学需氧量(COD)去除效果,其中运行长期时间内对各项污染物的去除率在50%~70%,表明采用粒料砌块技术可较为有效地保证人工湿地的长期净化效果。Higher disposal rate of N and P and lower cost on maintaining and management makes constructed wetland to be an ideal method to purify rural domestic sewage,however,the ubiquitous clogging is one of the major impediments to the promotion of constructed wetland. Ananti-clogging constructed wetland based on an aggregates block method was used to purify rural domestic sewage in Guangdong, results indica-ted that this constructed wetland showed a good disposal rate on NH^-N,TP and COD in both short and long term. The disposal rate on every contaminant were all during 50% and 70% in the long-term,which demonstrated that the aagregates block maintain the long-term purifying efficiency of constructed wetland.
