摘要
安徽省某上市企业,在电镀生产过程中产生一股化学镀镍废水,该类废水中含有各种络合剂及助剂等物质,严重影响重金属镍、磷酸盐等去除;用酸性氧化沉淀+离子交换深度处理法工艺处理该镍系废水,经调试运行表明该方法处理稳定可靠,处理效果优良,处理后出水水质达到《电镀污染物排放标准(GB21900--2008)》表三标准,即出水总镍≤0.1 mg/l、总磷≤0.5 mg/l。
A listed company in Anhui Province,electroless nickel plating wastewater was produced in the electroplating process,this kind of waste water contains a variety of complexing agents and additives and other substances, seriously affect the removal of metal nickel, phosphate, etc.; The chemical nickel wastewater was treated by the method of oxidation sedimentation and ion exchange. The results show that the method is stable and reliable and the treatment effect is good, The main pollutant total nickel, phosphate by the treatment of the effluent water quality to meet the standard of electroplating pollutant discharge GB21900--2008） table three, That is the total nickel ≤ 0.1 mg/1, TP ≤ 0.5 mg/l.
