摘要
在煤矿生活污水深度处理的混凝处理前,投加高锰酸钾复合药剂(PPC)预处理,研究了PPC的对混凝处理的强化效应。实验结果表明:PPC预处理对煤矿生活污水深度处理的混凝处理具有很好的强化效应,能显著提高聚合氯化铝(PAC)的对CODMn和浊度的去除率;当PPC的投加量为4 mg/L时,CODMn和浊度的去除率分别提高21%和40%。
The enhanced effect of Potassium Permanganate Composite chemicals（PPC） in coal mine domestic sewage advanced treatment was studied through a pre-treatment with PPC before coagulation treatment.The results of the test showed that the pre-treatment with PPC had a very good enhanced effect on coagulation treatment,enhanced the removal rates of turbidity and CODMn in the process of Poly Aluminum Chloride（PAC） coagulation,and that when the dosage of PPC was 4 mg/L the removal rates of turbidity and CODMn in increased by 21% and 40% respectively.
