摘　　要：各种镀镍工艺的含镍混合废水,由于废水中镍与水中各种有机物、无机物形成多种形式的络合物,化学沉淀难以完全去除镍离子。文章对此含镍废水首先采用Fenton试剂氧化,后采用NaClO氧化,最后经化学沉淀处理,使最终出水上清液镍离子浓度低于0.1 mg/L,该方法对含镍废水中氮、磷及COD等污染物的去除效果也非常显著。Due to all kinds of organic and inorganic pollutants in the water, various nickel complexes form. Chemical precipitation cannot completely remove the nickel ion in the mixed wastewater containing nickel. In the paper, the wastewater containing nickel treated by Fenton reagent oxidation - NaClO oxidation - chemical precipitation process, the final effluent nickel ion concentration was lower than 0.1 mg.L4, the removal of nitrogen, phosphorus and COD pollutants was also significant.
