摘　　要：在化学镀镍废水中添加高效绿色氧化剂SK-901可降低化学镀镍废水中TP、COD_(Cr)、氨氮等污染物的含量。以某化学镀镍废水为处理对象,对其污染物深度处理的去除效果进行试验验证。研究发现,SK-901对化学镀镍废水中TP、COD_(Cr)、氨氮污染物能起到一定的去除作用。通过正交试验得到最佳处理工艺条件:反应pH值为10.0,按投加量为25 mL/L向水样中加入质量浓度为10000 mg/L的SK-901水溶液,反应1.5 h后加入适量絮凝剂,絮凝沉淀后过滤。SK-901处理化学镀镍废水可与其他氧化技术联用,拓宽其适用范围。Efficient green oxidant SK-901 was added in electroless nickel plating wastewater,which could reduce the contents of pollutants such as TP,COD_(Cr) and ammonia nitrogen.Taking a electroless nickel plating wastewater as the treatment object,experiments were carried out to verify the removal effect of pollutants in advanced treatment.Results showed that SK-901 had a certain removal effect of TP,COD_(Cr),ammonia nitrogen and other pollutants in electroless nickel plating wastewater.The optimal treatment conditions were obtained through orthogonal test:react pH value was 10,added a mass concentration of 10000 mg/L SK-901 solution with dosage of 25 mL/L to the water sample,reaction time was 1.5 h,while added appropriate amount of flocculant,and filtered after flocculation and precipitation.SK-901 treatment of electroless nickel plating wastewater could combined with other oxidation technologies to broaden its application range.
