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.
