Abstract:
Based on the characteristics of the chromium-containing, nickel-containing and integrated electroplating wastewater from a machinery company in Kunshan city, China, the three kinds of wastewater have been treated by physico-chemical and bio-chemical methods, respectively, after collected by classification. The results show that the physico-chemical and bio-chemical technologies for treating electroplating wastewater are effective and stable. The effluent of the whole system can meet the requirements of Emission Standard of Electroplating Pollutants(GB 21900—2008), in which NH4+-N and total phosphorus reach the local standard of Discharge Standard of Main Water Pollutants for Municipal Wastewater Treatment Plant & Key Industries of Taihu Area(DB 32/1072—2007).

摘要:
根据昆山某机械公司排放的含铬、含镍及综合电镀废水的性质,采用分类收集后,分别以物化法及生物法对上述3种废水进行了处理。调试运行结果表明:采用物化法及生物法处理电镀废水稳定可靠,处理效果较好,系统整体出水达到了《电镀污染物排放标准》(GB21900—2008)要求,其中氨氮和TP达到了《江苏太湖地区城镇污水处理厂及重点工业行业主要污染物排放限值》(DB 32/1072—2007)要求。
