摘　　要：水库富营养化和高藻问题严重影响了水厂的供水水质,为提高供水的安全性,采用水生动植物组合净化水库水。在河蚌、螺蛳投加密度分别为2只/m^2+20只/m^2,4只/m^2+35只/m^2,6只/m^2+50只/m^2,轮叶黑藻、美人蕉覆盖率分别为80 g/m^2+30%,120 g/m^2+40%,160 g/m^2+50%的条件下,考察了水生动植物联合对TN、TP、NH3-N、高锰酸钾指数等水质指标及藻类密度的去除效果。结果表明,河蚌、螺蛳投加密度为4只/m^2+35只/m^2、轮叶黑藻和美人蕉覆盖密度为120 g/m^2+40%的净化效果优于其他二组。Eutrophication and high algea-bearing reservoirs posed a great impact on water supply quality of purification plant.Water purification of reservoirs by aquatic animals and plants was carried out to improve the safety of water supply.Three combination test plans referring to throw-in density of mussels and snails(2 pcs/m^2+20 pcs/m^2,4 pcs/m^2+35 pcs/m^2,6 pcs/m^2+50 pcs/m^2),three combination test plans referring to coverage of hydrilla verticillata and canna(80 g/m^2+30%,120 g/m^2+40%,160 g/m^2+50%)were established to investigate the changes of TN,TP,NH 3-N and permanganate index with time.The result showed that the optimum combination test plan was 4 pcs/m^2+35 pcs/m^2 in terms of mussels and snails,coverage of hydrilla verticillata and canna was 120 g/m^2+40%throw-in density.
