摘要
对用钢渣处理含砷废水进行了试验。用配水探讨了钢渣投加量、水样ＰＨ、混合时间等因素对除砷效果的影响，结果表明，钢渣具有较好的除砷效果。在水样ｐＨ１．５－９．０、Ａｓ（Ⅲ）含量１０－２００ｍｇ／Ｌ时，按砷／钢渣质量比为１／２０００投加钢渣，砷去除率达９８％以上。此法简单方便、处理费用低，为含砷废水的处理提供了一条新途径。
The treatment of arsenic-containing wastewater prepared in the laboratory has been tested with steel slag. The effects of slag dosage,pH of wastewater, and mixing time on the removal efficiency of arsenic were studied.The results showed that steel slag had a high capacity of removing arsenic, with the efficiency coming up to more than 98%, under the conditions of 1.5-9.0 of wastewater pH value,10-200mg/L of arsenic, 1/2000 of As/slag. This method is simple and low cost, providing a new way for the treatment of arsenic-containing wastewater.
