摘要

研究了铁盐和铈盐改性水粒渣对含铜废水的吸附过程及作用机理。结果表明，在室温为20℃、投加量为6g/L、pH为7、反应时间为60min的条件下，处理100mL20mg/L的铜废水，去除率达到93.64%。改性水粒渣对铜的吸附最符合Temkin吸附等温线，吸附等温线的线性变换结果为qe=20.71 lce -4.2413, R2= 0.9531。

Treatment of Wastewater Containing Copper by Modified Water Granulated Slag

The process and action mechanism of the copper wastewater adsorption accomplished by ferric salt and cerous salt modified water granulated slag were studied in this paper. Results showed that under the conditions of room temperature of 20¡æ, dosage of 6g/L, pH 7, reaction time of 60min to treat 100mL20mg/L copper wastewater, the removal rate reached 93.64%. The adsorption of modified water granulated slag to copper fits the Temkin adsorption isotherm best and the result of linear transformation of adsorption isotherm is qe=20.71lnCe-4.2413, R2= 0.9531.
