摘要
利用生物塘对富营养化巢湖水进行中试,结果表明:浮萍、黑藻、狐尾藻和芦苇对总氮、总磷均有较好处理效果,其中黑藻对总氮、总磷的处理效果最好,芦苇对叶绿素的处理效果最好。7月份是生物塘处理污染物的最佳时期,4种水生生物的综合生物塘对总氮、总磷和叶绿素的最高去除率分别为92.0%、89.2%、97.8%。
Pilot-scale biological pond with duckweed,hydrilla verticillata,water milfoil and phragmites communis was used to treat eutrophication water in Chaohu Lake.The results show that the 4 hydrobios have good effect of removing TN and TP,of which hydrilla verticillata has the best effect on TN and TP,and reed has the best effect on chlorophyll.The highest removal rate of TN,TP and chlorophyll by the pond with these hydrobios is 92.0%,89.2% and 97.8% respectively during July.
