金属硫化物矿区的尾矿在空气、水和微生物等的共同作用下，会产生大量含有毒有害重金属的酸性矿山废水，造成矿区及下游水体和土壤的严重污染。该文结合课题组研究，介绍以农业废弃物为原料开发改性玉米秸秆、花生壳、稻草等吸附材料，吸附去除酸性矿山废水中的重金属离子及其吸附机理，以及实地应用于东江源矿区污染控制示范工程中的重金属吸附去除案例，为矿区重金属污染源头控制研究提供理论基础和技术支持。

Mine tailings in metal sulfide mine areas can generate and release huge amounts of acid mine drainage ( AMD) containing poisonous heavy metals, and result in serious contamination of local and downstream environ-ment of water and soils.In this paper, agricultural wastes such as corn stalk, peanut shell and straw were modified successfully to produce efficient adsorbents for the removal of heavy metal ions from AMD, and the adsorption mechanism was discussed in detail.Furthermore, adsorption technique developed based on these adsorbents was applied to the project “Dongjiang yuan mine pollution control demonstration”.
