The main reasons were that the algae and organism in the water decreased the ability of removing pollutants by coagulations, the algae which grown again in the open sedimentation tank weakened the removal effect of algae by coagulation; because of the accumulation of algae and algae toxin in the filtration tank, the concentration of algae toxin in the effluent increased; by the function of fluid chlorine, the algae and organisms after the filtration will release microalgae toxin and produce a lot of byproduct such as microalgae toxin, sobomyl and so on, meanwhile, the chlorination produce considerable halide and halo-acetic acid and other disinfection byproduct.

主要表现在藻类和溶解性有机物的存在降低了混凝去除污染物的能力；藻类在露天平流沉淀池中再生长，抵消了混凝除藻效果；藻类和藻毒素在滤池中积累，导致滤后藻毒素升高；穿透滤池的藻类和有机物在液氯作用下，释放微囊藻毒素、土臭素和二甲基异冰片等胞内物质，同时生成数量可观的卤代烃和卤乙酸等消毒副产物。
