Within 90 days of the treating period,there was a sufficient and high removal rate of nitrogen under the planted float system,which occupy 20%area of the pond. The removal rate of TN,NH_4~+-N,NO_2~--N,NO_3~--N was 38.8%,51.2%,49.7%,69.6%.
该系统的净化效果与浮床植物系统占水面的比例有关,占池塘面积20%的浮床植物系统在试验90d时对池塘上层水体的TN、NH_4~+-N、NO_2~--N、NO_3~--N去除率分别为38.8%、51.2%、49.7%和69.6%。
