摘要
研究电凝聚处理生活污水的有效性和可行性。采用铝铁电极组、铝不锈钢电极组和双铁电极组的电极构造方式,进行pH值、电解时间、电流密度、投加电解质、温度和电极连接方式等影响因素的静态试验。试验结果表明:在原水pH值6.8、电解时间30min、电流密度0.25A/dm2的条件下,COD、SS及色度去除率分别在68%、69%和88.1%以上。
The availability and feasibility of domestic sewage treatment by electrocoagulation were studied. The electrode structural forms of aluminura-iron electrode, aluminum-stainless steei electrode and double iron electrode were used to carry out the static test of some influence factors, such as pH, electrolytic time, current density, dosing electrolytes, temperature and electrode connecting ways： It was shown that, under the conditions of pH 6.8, electrolytic time 30min, current derlsity 0.25A/dm^2, the removal rates were over 68%, 69% and 88.1% respectively.
