光合细菌净水剂清除滇池草海蓝藻的试验研究

Research on Photosynthetic Bacteria Removes Cyanophyceae in Dianchi Lake

光合细菌（ＰＳＢ）净水剂对滇池草海蓝藻清除有较好效果，在滇池草海约８００ｍ３围栏水域的现场试验中，叶绿素－ａ去除率在７５％以上，藻量去除率在９０％以上，平均透明度从０３ｍ增加到１０６ｍ，基本上已达到试验预期目标，且有操作简便，无二次污染产生等特点。

The photosynthetic bacteria (PSB) have good effect in removing Cyanophyceae in Dianchi Lake.The removal efficiency of Chl-a maintains at an average level of 75% and that of thealgae quantity is more than 90%.The average transparency reaches 1 06cm from 0 3cm.It is proved that the photosynthetic bacteria are effective Cyanophceae-removing reagent featuring convenient operation and non-secondary pollution.
