摘　　要：取某村水塘水和某矿山水为试验对象,研究以钢渣为主的复配吸附材料对水中铁、锰的吸附效果。结果表明,吸附材料对水塘水吸附后水样呈酸性,铁、锰的去除率分别在70%、25%以上,吸附材料对矿山水吸附后水样呈碱性,铁、锰去除率分别在95%、40%以上。在水样循环处理中,一次处理后,铁、锰去除率分别为91.27%、36.22%,二次处理后,铁、锰去除率分别为98.56%、99.79%,表明在混合水样中对铁的吸附优先于对锰的吸附。复配吸附材料对铁容量大于7.997 g/kg,对锰的吸附容量约为991.82 mg/kg。Taking the pond water in a village and the water in a mine as experimental objects,we study the adsorption effect of steel-slag-based composite adsorbent on iron and manganese in water.The experimental results show that the sample is acid after the adsorption material adsorbs the water in a village pond.The removal effect of iron and manganese are 70%and 25%,respectively.The water sample is alkaline after the adsorption material adsorbs the mine water.The removal effect of iron and manganese are above 95%and 40%respectively.In the water sample circulation treatment,the removal effect of iron and manganese after one treatment are 91.27%and 36.22%respectively;After the second treatment.the removal effect of iron and manganese are 98.56%and 99.79%,respectively,which Show that the adsorption of iron is higher than that of manganese in mixed water samples.The adsorption capacity of the adsorbent for iron is above 7.997 g/kg,for manganese is about 991.82 mg/kg.
