摘要
以某受污染地表水为研究对象,考察了高锰酸盐复合药剂(PPC)强化混凝工艺的除污染效能。静态试验结果表明,高锰酸盐最优投加方式应在混凝剂前投加,预氧化时间为20～40min,投量为1.2～2.4mg/L。生产性试验结果表明,采用高锰酸盐预氧化技术可以提高常规给水工艺去除有机污染物效能,使出厂水水质优于国家饮用水水质标准。
The effectiveness of PPC-enhanced coagulation process for pollutants removal from surface water was investigated. The lab-scale test indicated that PPC should be added before coagulation; the oxidation time is from 20min to 40 min and the optimal dosage, from 1.2mg/L to 2.4mg/L. The industrial operation data showed that PPC preoxidation exhibited good efficiency of removing pollutants; the effluent indexes were superior to the national drinking water standards.
