【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。更多还原

【Abstract】 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.更多还原
