Shanyin county, an area prevalent of endemic arsenic poisoning in Shanxi Province, was selected as the experimental field to verify the methods studied for removal arsenic from dispersed drinking water. The results showed that the desired goal has been achieved from the field study. The results confirmed that arsenate could be removed from drinking water by using ferric sulfate or aluminum sulfate as coagulants and employing sand filtration. Javelle water(sodium hypochlorite) is an effective oxidant for arsenite. The performance of iron oxide-coated sand developed in this study was good for arsenic removal. Further study and application is needed.
山西省山阴县是山西省地方性砷中毒的高发地区，被选为实验场地，以验证所研究的从分散饮用水中去除砷的方法。结果表明，现场研究已达到预期目标。结果证实，使用硫酸铁或硫酸铝作为混凝剂并采用砂滤可以从饮用水中去除砷酸盐。次氯酸钠溶液（次氯酸钠）是亚砷酸盐的有效氧化剂。本研究开发的涂覆氧化铁的砂对砷的去除性能良好。需要进一步研究和应用。
