分析了国内煤矿区污水的主要水质类型、矿区污水处理的技术现状。指出国内煤矿区矿井水处理主要采用常规的混凝沉淀处理工艺,高矿化矿井水处理主要采用反渗透技术,酸性矿井水处理主要有中和法、生物化学方法、湿地生态工程处理法等;煤泥水的处理主要集中于药剂优化、设备改进的研究;矿区生活污水处理除采用活性污泥法改进工艺处理外,自然生态的人工湿地、氧化塘、土地渗滤等处理技术将成为煤矿企业污水处理的发展方向。
Analyzed the main types of water quality in the domestic coal mining area, the technical status of the sewage treatment in the mining area. It is pointed out that the domestic coal mine water treatment mainly adopts the conventional coagulation and sedimentation process, the reverse osmosis technology is mainly used in the water treatment of the high mineralized mine, the neutralization method, the biochemical method and the wetland ecological engineering treatment method are mainly used in the acid mine water treatment. The treatment of slime water mainly focuses on the optimization of medicament and the improvement of equipment. In addition to the activated sludge treatment and improvement, the treatment of domestic wastewater in the mining area will be treated as natural wetlands, oxidation ponds, landfill leaching and other treatment technologies. The direction of development.
