摘要
针对南水北调邯郸段原水水质夏季藻类增多的现象,通过烧杯试验对比研究了单独使用混凝剂、活性炭吸附和负载高锰酸钾活性炭吸附对叶绿素a、浊度和UV254的去除效果。结果表明:负载高锰酸钾活性炭对原水中污染指标去除率高于单独使用混凝剂和活性炭吸附,当负载0.4 g/L高锰酸钾的活性炭投加量为15 mg/L时综合去除效果最优,此时对原水中叶绿素a、浊度和UV254的平均去除率分别为77%、92%和61%。活性炭负载高锰酸钾后可使其碘值及表面含氧官能团增加,从而起到强化混凝的作用。
In view of the phenomenon of algae overgrowth in raw water of Handan section of the South-to-North Water Transfer Project in summer,removal efficiencies of chlorophyll-a,turbidity and UV254 by coagulant,activated carbon adsorption and activated carbon loaded with potassium permanganate adsorption were compared in a beaker test.The removal efficiency of raw water pollution index of activated carbon loaded with potassium permanganate was higher than that of coagulant or activated carbon adsorption.When dosage of activated carbon loaded with 0.4 g/L potassium permanganate was 15 mg/L,the best integrated removal effect was obtained,and the average removal rates of chlorophyll-a,turbidity and UV254 in raw water were 77%,92%and 61%,respectively.Activated carbon loaded with potassium permanganate can increase its iodine value and surface oxygen-containing functional groups,thus enhances the coagulation efficiency.
