| 摘 要： | 分别采用三氯化铁和硫酸亚铁作为化学沉淀除砷药剂，比较研究了三氯化铁和硫酸亚铁处理高浓度模拟含砷（V）废水的工艺条件。试验结果表明，在最佳条件下三氯化铁砷去除率为99．92％，硫酸亚铁的砷去除率为99．97％；三氯化铁的用量少且产生的含砷沉淀物也较少。但由于三氯化铁中氯离子较高，导致滤液中氯离子严重超标，不利于废水的达标排放。因此，硫酸亚铁更适合处理工业高浓度含砷废水。

| Abstract: | A comparative study of treating waste water with high-concentration arsenic （V） by FeCl3 and FeSO4 respectively is carried out. Arsenic removal efficiencies by FeC13 and FeSO4 were 99.92% and 99.97% , respectively. In case of FeCl3 , the dosage of treatment agent and amount of arsenic precipitates were less, but the residue Cl^ - in filtrate was higher than the discharge limit. So FeSO4 is more suitable for treating industrial waste water with high-concentration arsenic |
