摘要
针对中小型的电镀厂产生的综合电镀废水,采用Fe/C微电解联合Fenton方法进行试验研究。试验结果表明,Fe/C微电解最佳工艺条件为:p H=3,Fe/C质量的投加比2∶1,反应时间60 min,汽水比20∶1;Fenton氧化的最佳工艺条件为:p H=4.0,反应时间60 min,H2O2投加量10%,然后投加Na OH调节PH=10.0左右共沉淀。COD去除率达95%,出水重金属离子低于电镀废水处理排放标准。
The combined techniques of Fe/C micro-electrolysis and Fenton was used to treat the comprehensive electroplating wastewater produced by a small or medium-sized electroplating industrial park. Results show that the appropriate parameters of Fe/C micro-electrolysis areas follows： pH=3 ,Fe/C dosage ratio of 1： 1, reaction time of 60 min, gas-water ratio of 20： 1. The appropriate parameters of Fenton reagent are pH=3, reaction time of 60 min, H2O2 dosage of 10 %, and the sodium hydroxide with optimal pH-10 was added for chemical co-precipitation, which could meet the discharge standard of electroplating wastewater.
