摘要
饮用水砷污染问题受到全世界的关注。为了应对水源砷污染以及水源砷突发污染事件的发生,文章对水源中的砷(Ⅲ)进行了去除实验研究。结果表明,当水中砷(Ⅲ)含量﹤0.06mg/L(超标6倍)时采用混凝沉淀工艺可使出水达标;当砷(Ⅲ)超标倍数更高时,则采用氧化处理+混凝沉淀工艺可有效去除水中的砷,使得出水达标。
Arsenic pollution in the drinking water was got worldwide attention, for coping the Arsenic pollution and water pollution incident in urban water supply area in China. In the paper, the Arsenic （Ⅲ） was removed in the water uder laboratory conditions, the results showed that the content of the Arsenic （Ⅲ） in the water was less than 0.06 mg/L（over standard 6 times）, using the coagulation-settlement process could reach the standard, when the Arsenic （Ⅲ） in the water over standard was higher, using the oxidation treatment ＋ coagulation-settlement process could reach the standard.
