摘　　要：为解决露天采煤矿区酸性废水造成的附近水体和土壤酸化污染问题,本文以福泉市皮陇河生态修复项目为例,对大气降水淋滤煤矸石产生酸水、废弃露采坑中残留高硫煤及硫化矿物与积水作用产生酸性积水进行处理,并对废弃露采坑中酸性水通过采坑边邦及底板下渗对地下水的污染问题进行治理,效果较为显著。治理区域下游河流断面水质达到灌溉标准,为矿山解决生态环境污染问题的同时,也为国土空间生态修复打造了可行性强、可供复制的治理样板。In order to solve the acid pollution problem of nearby water bodies and soil which caused by acid wastewater in the opencast coal mine, the project of Pilonghe ecological treatment in Fuquan city is taken as the example, the acid wastewater of atmosphere water leaching coal gangue, the acid hydrop formed by residuary sulfur coal and sulfide mineral with hydrops in abandoned open mining pit were treated, the underground water pollution of infiltrated acid wastewater through the mining pit edge and basement in the abandoned open mining pit were improved, the effect is obvious.The sectional water quality of downstream rivers in the treating area reached the required standard of irrigation.The ecological environment pollution of ore was treated, meanwhile the high-probability and reproducible treating simple were made for ecological restoration of national space.
