目的 探讨聚合硫酸铁饮水除砷的效果。方法 每升含砷（As3+）水样加氯1mg,混匀后加混凝剂聚合硫酸铁溶液[ω（Fe）=9.5％]0.1ml。结果 含As3+1.0mg/L的水样经处理后As3+含量为0～0.024mg/L,铁含量<0.05mg/L。SO42-浓度在原水中为37.0mg/L,除砷后水中为80.0mg/L。均符合饮用水国家标准的限量要求。结论 聚合硫酸铁饮水除砷方法简便、费用低、效果好,有较好的推广应用价值。
Objective To investigate the effect of arsenic trioxide on polyferric sulfate drinking water. Methods Per liter of arsenic (As3 +) water samples chlorinated 1mg, mix coagulant ferric sulfate solution [ω (Fe) = 9.5%] 0.1ml. Results As3 + 1.0mg / L water samples treated As3 + content of 0 ~ 0.024mg / L, iron content <0.05mg / L. The SO42- concentration was 37.0 mg / L in raw water and 80.0 mg / L in water after arsenic removal. Are in line with drinking water national standards of the limited requirements. Conclusion Polyferric sulfate drinking water arsenic method is simple, low cost, good effect, and has a good promotion and application value.
