模拟水厂现行工艺对含镍污染原水进行处理，当原水中镍质量浓度超过0.03 mg/L时，经处理后无法保证镍去除达标。在水厂现有工艺基础上，通过投加高锰酸钾、助凝剂PAM和调节pH来强化镍的去除，试验结果表明，pH和高锰酸钾投加量是影响镍去除效果的两个主要因素。最佳去除率方案：高锰酸钾投加量为1.5 mg/L，调节pH为9.5，PAC投加量为18 mg/L，PAM投加量为1.0 mg/L。在此条件下处理镍质量浓度为0.1 mg/L的原水，出水剩余镍为0.009 mg/L，去除率达到91%，同时该条件可使质量浓度＜0.22 mg/L的镍污染原水处理后达标。高锰酸钾预氧化强化混凝可作为柳江沿岸水厂应对镍污染的一种有效应急处理措施。

The polluted raw water containing nickel has been treated by the present technology in a simulated water plant. When the mass concentration of nickel in raw water is higher than 0.03 mg/L ,it is impossible for the treated water to surely reach the nickel-removing standard. Based on the present technology in the water plant ,the removal of nickel has been enhanced by adding potassium permanganate,coagulant aid PAM,and adjusting pH. The results show that its pH and the dosage of potassium permanganate are the two main factors which have effects on the re-moval of nickel. The optimal project of nickel removing is as follows:the dosage of potassium permanganate 1.5 mg/L, adjusted pH to 9.5,PAC dosage 18 mg/L,and PAM dosage 1.0 mg/L. Under these conditions,when the raw water with nickel mass concentration of 0.1 mg/L is treated ,the effluent residual nickel is 0.009 mg/L and its removing rate reaches 91%. Furthermore,these conditions can make the nickel polluted raw water,whose mass concentration is lower than 0.22 mg/L,reach the standard. Potassium permanganate pre-oxidation enchanced coagulation process can be used as an effective emergency treatment measure to remove nickel.
