摘要
研究了含铬、铜、锌电镀废水的处理方法。用BaCl2沉淀铬后,加入Na2SO4除去多余的钡,然后用NaOH沉淀Cu2+、Zn2+,经压滤后排出清水。
Treatment process of electroplating effluent of containing Chromium(Ⅵ),Copper(Ⅱ)and Zinc(11)has been studied in the paper.After Chromium precipitated by means of Barium Chloride,Sodium Sulphate solution was put into the wastewater for precipatating excessive Barium(Ⅱ).Copper(Ⅱ)and Zinc(Ⅱ)were precipitated with sodium hydrate solution and then the dreggy wastewater was treated by way of pressurized filtration before discharged.
