高锰酸钾及其复合药剂强化混凝除藻除嗅对比

Comparison between removals of algae and odor by coagulation and enhanced coagulation of potassium permanganate and its composite chemical

为净化地表水源,考察了高锰酸钾及其复合药剂对含藻水的强化混凝净水效能.结果表明,单纯混凝对含藻水的净化效果较差,只能去除部分藻类,对藻类引起的嗅味基本没有去除作用.采用高锰酸钾预处理后对净水效果有一定的提高,对嗅味也有一定的去除作用.而采用高锰酸盐复合药剂预处理对混凝的强化效果要远远高于高锰酸钾,对水中的藻类、嗅味及有机物的强化去除都有显著提高.

Experiments were conducted to compare the effects of removals of algae and odor from surface water by coagulation, and enhanced coagulation of potassium permanganate and potassium permanganate composite chemicals. Experimental results show that the conventional coagulation process can remove algae little, but cannot remove odor derived from algae, enhanced coagulation of potassium permanganate can improve the algae and odor removal rate to some degree, and enhanced coagulation of potassium permanganate composite can chemicals increases that greatly, and it is the most efficient process in removing algae, odor and organic matter derived from algae in surface water.
