摘　　要：以电镀生产工艺中产生的含氰、含铬电镀废水为研究对象 ,提出了硫酸亚铁 -粉煤灰法处理含铬废水 ,碱性氯化法处理含氰废水 ,将含硫酸废水用于处理过程中 pH值调节 ,确定各项处理最佳条件 ,经小试及生产试验表明 ,出水水质均达到了国家的排放标准。Based on the study of wastewater containing cyanogen and chromium compound produced from the process of the making of electroplate, the paper advances the new method of cyanogen removal and chromium removal by means of chemical method. At the same time, suiable parameters were established. Results of a small-scale test and a full-scale test show that cyanogen and chromium can be removed efficiently in the process. Cyanogen and chromium concentrations are lower than those in the wastewater discharge standards of China.
