摘　　要：采用不同结构(分层填埋和混合填埋)的复合微生态系统对模拟生活污水进行了处理研究。结果表明:在60cm/d的高水力负荷条件下,对COD、TN、NH4+-N和PO43--P的去除率,分层填埋系统分别为78.3%、36.9%、81.3%和50.8%;混合填埋系统分别为79.1%、41.5%、93.4%和86.7%。混合填埋系统对污染物去除效率高于分层填埋系统。植物对微生态系统的正常运行有重要作用。Experimental studies were done for the treatment of simulated sewage by micro eco-system of different structures including layered filling and mixed filling. Results showed that at a high hydraulic loading rate of 60cm/d, removal efficiency of CODcr, TN, NH4^＋-N and PO4^3--P were 78.3%, 36.9%, 81.3% and 50.8% respectively in the micro eco-system of layered filling while 79.1%, 41.5%, 93.4% and 86.7% in the mixed filling respectively. Removal efficiency of contaminant in the micro eco-system of mixed tilling was higher than those in the layered filling. The plants play an important role in micro eco-system.
