摘    要:针对人造金刚石厂的含镍废水,在常规电解方法的基础上,采用膜电解法对该含镍废水的处理和金属镍回收进行了研究,通过对不同条件下的阴、阳膜及组合方式的效果和优缺点进行比较。结果表明单阴膜法在处理pH值为0.5~1.0,初始镍的质量浓度为1000~2000mg/L的废水应用中有更好的处理效果。当电解的电流150mA,电压5V时,电解时间控制在8~10h,10h后离子交换富集,循环使用,其平均电流效率为78.4%,金属镍的回收率达到79.3%且纯度较高。

关 键 词:含镍废水  电解  膜电解法  镍回收

Abstract:The use of membrane electrolysis method in the treatment of nickel-containing waste water from diamond works on the basis of conventional electrolysis method and the recovery of metal nickel were studied. The effects, advantages and disadvantages of anionic and cationic membranes and their combinations under different conditions were compared. The results showed that monoanionic membrane method gave better results of treatment when used in the treatment of waste water whose pH value was 0.5 ~ 1.0 and initial nickel content was 1 000 ~ 2 000 mg/L. When the electrolytic current was 150 mA, the voltage was 5 V, the electrolytic time was controlled between 8~10 hours, and ion exchange method was used 10 hours later for enrichment and reuse of nickel, the average current efficiency was 78.4%, the recovery rate of metal nickel reached 79.3%, and the purity of the metal nickle was higher.
Keywords:nickel-containing wastewater  electrolysis  membrane electrolysis  nickel recovery
