| 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。

| Abstract: | 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 PO43——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 filling was higher than those in the layered filling.The plants play an important role in micro eco-system. |
