摘　　要：针对阜新矿区水资源短缺的问题,以阜新某煤矿为例,提出了矿井水处理的一般原则,阐述了矿井水初步处理和深度处理工艺流程,核算了矿井水利用的成本,分析了矿井水资源化的综合效益。研究表明,矿井水处理应遵循先易后难、由浅入深的原则,再根据回用目标和水质特征,设计处理工艺;通过混凝、沉淀、消毒等工艺初步处理矿井水,水质可达到煤炭工业污染物排放标准,并满足矿区工业用水需求;通过反渗透等工艺深度处理矿井水,水质可达到生活饮用水卫生标准,并满足矿区生产生活用水需求;矿井水初步处理运行成本约为1元/m3,深度处理运行成本约为2元/m3;矿井水处理及综合利用可有效节约地下水资源,减少污染物排放,缓解水资源供求矛盾,具有显著的综合效益。For the purpose of solving the shortage of water resources in Fuxin mining area,the general principles of mine water treatment were put forward based on a case study of a coal mine in Fuxin. The preliminary treatment process and deep treatment process were introduced. The costs of mine water utilization were accounted in order to analyze the comprehensive benefits of the mine water reclamation. The studies demonstrated that the mine water treatment should follow the principle of easy-to-difficult and shallow-to-deep,and then the treatment processes were designed according to the reuse target and water quality. Based on the preliminary treatment of mine water through such processes as coagulation,sedimentation and disinfection,the water quality of mine water can reach coal industry pollutant discharge standards and meet the demand of industrial water in the mining area. Furthermore,based on the deep treatment of mine water through such processes as reverse osmosis,the water quality of mine water can reach the health standards for drinking water and meet the demand of production and living water in the mining area. The operating cost of the preliminary treatment is about 1 yuan per ton,and the operating cost of deep treatment is about 2 yuan per ton. Finally,the treatment and utilization of mine water,which can save groundwater resources,reduce pollutant emissions and ease the contradiction between water supply and demand effectively,has significant comprehensive benefits.
