摘　　要：基于前期筛选的三种滏阳河原生水生植物,通过对三种植物的两两结合,构建出狐尾藻组、金鱼藻组、篦齿眼子菜组、狐尾藻-篦齿眼子菜组、狐尾藻-金鱼藻组及金鱼藻-篦齿眼子菜组6种植物组,并通过6种植物组对富营养化水体的修复实验,分析其净化效能。结果表明:6种植物组对水体中所含污染物质均有很好的去除效果,其对氨氮的去除率均达95%以上,对TN的去除率达75%以上,对TP的去除率达47%以上,对CODMn的去除率达58%以上,对叶绿素抑制效果明显,通过横向对比分析,植物组合对NH+4-N、TN、TP及叶绿素有较好地处理效果,对CODMn的处理效果与植物单体类似。基于AHP对各水生植物组合进行综合评价,狐尾藻+篦齿眼子菜组合得分最高,表明其在水质净化全过程对污染物均有较好地去除效果。This study is based on three raw plants in Fuyang,which are combined with double of three species of plants. In this study,6 plant groups,the watermifoil group,the hornwort Group,the Potamogeton pectinatus group,the watermifoil-Potamogeton pectinatus Group,the watermifoil-hornwort Group and the Potamogeton pectinatus-hornwort Group are constructed. Through the Restoration experiment of eutrophic water,the purification efficiency of six groups of plants is analyzed. The results show that all the 6 plant groups has good removal effects on the contaminated substances,the removal rate of ammonia nitrogen is over 95%,the removal rate of TN is over 75%,the removal rate of TP is over 47%,the removal rate of CODMnis more than 58%,the chlorophyll has some inhibitory effect. At the same time,by horizontal contrast,the plant assemblage has a better treatment effect on NH＋4-N,TN,TP and chlorophyll,and the treatment effect of CODMnis similar to that of the plant monomer. The AHP method is used to evaluate the combination of plant combination. The results show that the combination of the watermifoil-Potamogeton and pectinatus Group has the highest score,indicating that it has a good removal effect of pollutants in the whole process of water purification.
