强化混凝组合工艺处理微污染水源水研究

Study on Treatment of Micro-polluted Raw Water by Enhanced Coagulation

采用静态烧杯实验考察了强化混凝组合工艺解决某水厂出水COD_(Mn)、色度及铝含量超标的问题。结果表明,高锰酸盐与次氯酸钠联合预氧化,配合使用少量黏土、粉末活性炭混合物强化混凝,可以在氯化物不超标的情况下,使出水COD_(Mn)、色度及铝含量得到有效控制。

Enhanced coagulation process was investigated to solve the over standard problems of COD（Mn）,colourity and aluminium using static beaker experiments. The results showed that the above indexes could be controlled effectively without the over standard of chloride when potassium permanganate and sodium hypochlorite were used as oxidants,combined with the mixture of clay and powdered activated carbon to enhance coagulation.
