摘　　要： 选取一种钢铁工业废物——钢渣处理含汞海水,探讨了钢渣含量、钢渣粒径和汞初始浓度对除汞效果的影响.研究结果表明:钢渣对汞具有较好的去除效果,投加5 g/L 80目(粒径<0.18 mm)钢渣处理0.5μg/L的含汞海水,汞的去除率达到90.6%.钢渣对汞的去除主要是吸附作用,通过钢渣处理能够显著降低污染海水中汞浓度,为解决海洋汞污染提出了一种有效途径. The treatment of mercury-containing sea water with steel industrial waste-steel slag has been studied in this paper.The effects of slag dosage,diameter of particles and the mercury original concentration on the removal efficiency of mercury were studied.The results showed that steel slag had a high capacity of removing mercury,with the efficiency coming up to 90.6%,under the conditions of adding 5 g/L and 80 mesh（less than 0.18 mm） of steel slag into 0.5 μg/L of mercury-containing seawater.Mercury concentration in polluted sea water was significantly reduced by adsorption,which was a new way for the treatment of pollution of mercury in sea water.
