为研究水生植物对富营养化水体的净化效果,选择风车草( Cyperus involucratus,A) 、狐尾藻( Myriophylium spicatum,B)和黑三棱( Sparganium stoloniferum,C) 3种水生植物,对其单一、2种和3种不同组合进行水培试验,通过实验室模拟富营养化水体,对总氮( TN) 、总磷( TP)和化学需氧量( COD) 3个水体富营养化指标进行检测。结果显示,随着处理时间的增加,各组对富营养化水体中TN、TP和COD的去除率呈递增趋势;至36 d试验结束时,各组对富营养化水体中TN、TP和COD的去除率,ABC组显著大于AB、AC和BC各组,AB、AC和BC各组显著大于A、B和C各组,ABC组合对富营养化水体中TN、TP和COD的去除率分别达到98.64%、...

In order to study the purification effect of aquatic plants on eutrophic water body,three aquatic plants, including Cyperus involucratus ( A),Myriophylium spicatum ( B),and Sparganium stoloniferum ( C),were selected. Plant combinations of single,2 or 3 species were used by simulating eutrophication water body in laboratory. The eutrophication indexes of total nitrogen ( TN),total phosphorus ( TP) and chemical oxygen demand ( COD) were measured. The results showed that the removal rates of ABC combination on TN,TP and COD in eutrophic water were 98.64%,98.36% and 95.49%,respectively. With the i...
