摘要
采用硫酸亚铁沉淀-沉渣回流-次氯酸钠氧化工艺处理CN-含量为4mg/L、S2-含量为6mg/L的煤气洗涤废水,CN-的去除率可达95%以上,S2-的去除率近100%。
The coal-gas washing wastewater containing 4mg/L of cyanide and 6mg/L of sulfied has been treated by a ferrous sulfate precipitation-precipitate backflow-sodium hypochlorite oxidation process.The removal efficiencies of cyanide and sulfide could come up to 99% and almost 100% respectively.
