摘要
在扬州万福闸水源地闭闸期间的高藻期考察了采用高锰酸钾(PP)预氧化和粉末活性炭(PAC)吸附与常规工艺联用对高藻水的净化效果,优化了PAC的投加位置。试验结果表明,取水口投加1.5 mg/L的PP,混凝前投加15 mg/L的PAC,该工艺与常规工艺联用对高藻水的净化效果明显优于常规工艺。
The removal efficiencies of conventional process combined with Potassium Permanganate （PP） pre-oxidation and pow- dered activated carbon （PAC） absorption for high-algae raw water were investigated. Point of adding PAC was optimized. The result of the test showed that when adding PP in the intake with the dosage of 1.5 mg/L and adding PAC before coagulation with the dosage of 15 mg/L, purification effect high-algae raw water is much better than the effect of only conventional process.
