| 摘 要： | 以采用黄河侧渗水为原水的柿园水厂现有常规净水工艺为基础,开展了水源突发性砷污染的应急处理工艺研究.结果表明,聚合硫酸铁对砷的混凝去除效果优于三氯化铁;液氯投加量为2.0 mg/L时,除砷效率均最佳;调节pH对砷去除效果的改善不明显.通过正交试验确定出适合黄河侧渗水砷去除的最佳参数:聚合硫酸铁投加量10 mg/L,硅酸钠投加量3.3 mg/L,液氯投加量2.0 mg/L,沉淀时间60 min.混凝剂的投加量是影响除砷效果的最显著因素.

| Abstract: | Research on emergent treatment process of arsenic contamination in source water was conducted based on conventional water treatment process in Shiyuan Waterworks which took Yellow River seepage water as source water.The results showed that polyferric sulfate was superior to ferric chloride for the removal of arsenic.Optimal efficiency of arsenic removal could be obtained when liquid chlorine was dosed at 2.0 mg/L.Obvious efficiency could not be obtained by adjusting pH.Optimal parameters for arsenic removal... |
