摘要
采用沸石及高锰酸钾在一定条件下制备沸石载高锰酸钾(ZCM)药剂,研究了不同投量下ZCM对铜绿微囊藻及藻毒素的去除和控制效果.结果表明,ZCM对单一铜绿微囊藻水样中藻类生物量和浊度均有明显的去除效果,在投量为0.11和0.17 g/L时,对叶绿素a的去除效果最好,5 d去除率分别为82%和86%,浊度降至检测限以下.ZCM药剂对铜绿微囊藻藻毒素MC-LR也有明显的去除效果,最佳药剂投量0.22 g/L时去除率达96.9%.
In this study, ZCM （zeolite carrying potassium permanganate） algaecide was developed and its removal effect of microcystis aeruginosa and controlling effect of microcystic toxins were investigated. The results showed that ZCM algaecide could remove both algal biomass and turbidity in microcystis aeruginosa water sample significantly, and it achieved a good removal of chlorophyll a, and the removal rate was 82% and 86% respectively under the dosage of 0. 11 g/L and 0. 17 g/L after 5 days, while the turbidity fell bellow detection limit. With the algae removal, it indicated that ZCM algaecide could obviously remove microcystic toxins in the water sample as well. The most efficient dosages of removing MC-LR was 0.22 g/L, with the removal rate of 96.9%.
