研究了高锰酸钾与水合二氧化锰联用强化聚合氯化铝(PAC)混凝微污染地表水的效果。结果表明:与PAC单独混凝相比,强化混凝可将浊度去除率提高约3%,TOC去除率提高约30%;在浊度去除率相同的情况下,强化混凝工艺可节省约36%的PAC用量;当进水pH值及腐殖酸浓度在一定范围内变化时,强化混凝工艺对浊度和TOC的去除效果优于相同投加量的PAC,具有较强的抗水质变化冲击能力。
The effect of potassium permanganate combined with hydrated manganese dioxide on the surface polluted surface polluted by polyaluminum chloride (PAC) was studied. The results showed that turbidity removal rate increased by about 3% and TOC removal rate increased by about 30% compared with PAC coagulation alone. When the turbidity removal rate was the same, the coagulation process could be saved by about 36% of the PAC dosage. When the influent pH value and humic acid concentration varied within a certain range, the turbidity and TOC removal efficiency of the enhanced coagulation process was better than that of PAC with the same dosage, which had strong resistance to water Change the impact of capacity.
