摘　　要：根据上海老港垃圾填埋场渗滤液尾水的水质特性,研究黄菖蒲、菖蒲和再力花3种挺水植物在不同配置模式下,在室内静水实验中,其植物的生物量变化及对尾水的TN、TP和COD净化效果.结果表明,植物对渗滤液尾水的TN和TP净化效果显著,去除率均在75.1%以上,对COD的去除率最高为62.8%;其中,3种植物混合模式对TN和TP净化效果优于两两混植和单种种植,对COD净化效果差异性不显著.另外,净化效果与植物生物量、单位富集量和不同植物问的协同净化作用密切相关.因此,在净化水体时,有必要结合实际情况,针对性地进行植物配置模式优化,以确保净化效果更有效.Based on the water quality of landfill leachate tail water of the Laogang Garbage Landfill in Shanghai, the purification effect to TN, TP and COD in the tail water and biomass changes of three emerged plants Acorus calamus, Iris pseudacorus and Thalia dealbata in different configuration modes under hydrostatic conditions were investigated. Results showed that the purification effect to TN, TP of leachate tail water was distinct, the removal rate being over 75.1%, while the COD removal rate belows 62. 8%. TN, TP purification effect of the three plant mixed mode was superior to that of the two mixed modes and the single plant mode; but there are no significant differences to COD removal rate among different modes. It is necessary to consider the actual conditions to select suitable plant configuration mode to ensure more effective purification efficiency because the purification effect is closely related to plant biomass, enrichment of unit volume, and different cooperative purification between plants in purifying waterbody.
