利用电吸附技术去除水中过量砷的研究

Removal of Excessive Arsenic From Drinking Water by Electric Absorb Technology

目的 防治饮用水中过量砷对人体健康的危害。方法 利用电吸附技术(EST)去除水中过量的砷。结果 小试和现场试验结果表明,原水砷含量为0.06～0.33 mg/L时,出水砷含量均低于0.01 mg/L,符合国家生活饮用水卫生标准的要求。结论 电吸附技术效果稳定,操作简便,成本低于其他离子去除技术,可在高砷地区推广应用。

Objective To control the hazardous effects of excessive arsenic in drinking water on human health. Methods The experiment on the removal of excessive arsenic from drinking water by electric absorb technology (EST) was performed. Results The pilot experiment and experiment in situ showed that, after treatment by EST, the contents of arsenic in source water(0.06-0.33 mg/L) decreased to the levels of <0.01 mg/L in finished water, which accorded with the Sanitary Standard for Drinking Water. Conclusion EST presented stable removal effects, simplified operation and lower costs compared with those of other deionizing technology. It could be widely applied in the high-arsenic area.
