| 为研究废弃煤矿矿井废水治理的有效方法与途径，以贵州省凯里鱼洞河流域废弃煤矿矿井废水治理工程为例，通过资料收集、实地调研、水样采集及检测，对目前省内主要治理模式及其治理后的效果进行研究。结果表明:传统的“井口废水收集+集中物理化学处理”的环境工程模式适用条件简单、治理效果好，但不能实现一次性治理，后期运行成本高，技术可行但不经济；地质工程模式中的“井口封堵+下游帷幕”能够实现一次性源头根治，具有环境和经济效益良好且易于管理的优势。“井巷关键通道封堵”、“井巷封堵+上游帷幕”及“源头控减+井口湿地”治理效果欠佳，不能达到根治目的。为此，建议将“井口封堵+下游帷幕”模式作为未来废弃煤矿矿井废水治理的主要方式。研究成果可为贵州省内废弃煤矿矿井废水及水环境治理提供借鉴。 |

| In order to study the effective methods and approaches for the treatment of wastewater from abandoned coal mine shafts，taking the treatment project of wastewater from abandoned coal mine shafts in the Yudong River Basin，Kaili，Guizhou Province as an example，through data collection，field investigation，water sample collection and testing，the main treatment modes in the province at present and the effects after treatment were studiedThe results show that the traditional environmental engineering mode of “collecting wastewater at the wellhead + centralized physical and chemical treatment” has simple applicable conditions and good treatment effect，but it cannot achieve one-time treatment，and the later operation cost is highIt is technically feasible but not economicalThe mode of “wellhead plugging + downstream curtain” in the geological engineering mode can achieve one-time source treatment，and has the advantages of good environmental and economic benefits and easy managementThe treatment effects of “plugging key passageways in mine tunnels”，“plugging mine tunnels + upstream curtain” and “source control and reduction + wetland at the wellhead” are not satisfactory and cannot achieve the purpose of radical treatmentTherefore，it is recommended to take the mode of “wellhead plugging + downstream curtain” as the main method for the treatment of wastewater from abandoned coal mine shafts in the futureThe research results can provide reference for the treatment of wastewater and water environment from abandoned coal mine shafts in Guizhou Province |
