摘要
研究了用氧化与混凝组合工艺处理某锑冶炼厂排放的碱性含砷废水。研究结果表明,聚合硫酸铁较三氯化铁、硫酸亚铁对原水中砷的去除效果好;用氧化与混凝组合工艺较单纯用混凝工艺对砷的去除率高;双氧水、次氯酸钠这两种氧化剂中采用次氯酸钠氧化对原水中砷的去除效果及处理成本最佳。
In this study,oxidation - coagulation process is used for treating alkaline arsenic-containing wastewater in an antimony smeltery. The result shows that the PFS has the highest arsenic removal efficiency than FeCl3 and FeSO4, oxidation - coagulation process have higher arsenic removal rate than coagulation process. As an oxidizer, the removal efficiency and treatment cost of NaClO are better than H2O2.
