摘要
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。
ve To explore the effectiveness of removal of arsenic from drinking water by polyferric sul-fate. Methods Per liter water sample containing arsenic ( Ⅲ ) was added and homogenized with 1 mg chlorine and then was treated with polyferric sulfate [ω(Fe) = 9. 5% ] as a coagulant. Results The content of As3+ and iron were 0-0.024 mg/L and <0.05 mg/L respectively in arsenic-removed water sample with an original As3+ concentration of 1.0 mg/L. The concentration of SO42- was 37.0 mg/L in original water sample, and 80.0 mg/L in arsenic-removed water sample respectively. The levels of these 3 indexes all accorded with the related limits ruled by National Hygienic Standard for Drinking Water. Conclusion This method was easy, low cost and very effective, and presented better values for application and popularization.
