| 摘 要： | 试验模拟地下水成分,利用氧化混凝沉淀法,对比铁锰钙离子对于除砷效率的影响及其变化.实验研究结果表明,在铁离子5mg/L时,氧化混凝法对砷的去除率基本上可以达到90%.水体中的钙离子可以促进水中砷离子的沉淀分离,钙铁离子同时作用除砷效率更好,比单铁除砷效率提高一倍以上.单独的锰离子对混凝除砷效率有促进作用,当铁锰共存时,锰离子会促进氢氧化铁的形成,但同时会降低砷酸铁的形成率,造成混凝除砷效率略有降低.

| Abstract: | simulated groundwater water was targeted by process of of oxidation coagulation method.Arsenic removal efficiency and its changes was explored by various addition of Fe/Mn/Ca.Experimental results show that the removal rate of arsenic by coagulation method is basically up to 90% at a dosage of 5 mg/L.Calcium ions in the solution can promote the precipitation of arsenic separation and together with iron does better.manganese ions during coagulation can promote the removal rate of arsenic.When iron and mangane... |
