摘　　要：根据山西省水污染防治行动计划要求,煤矿外排矿井水污染物化学需氧量、氨氮和总磷指标需达《地表水环境质量标准》(GB3838-2002)Ⅲ类标准。磁窑沟煤业井下污水处理站现有工艺不能满足新标准要求,需进行提标改造。考虑到煤矿下水平延深及远景发展,在充分利用现有设施、设备基础上,采用“混凝+沉淀+迷宫斜板沉淀+多介质过滤+陶瓷膜过滤”等工艺进行改造。提标改造后的系统工艺先进,实用性强,技术可靠,能实现自动化控制和集约化管理,且经济合理、高效节约,污水处置率达100%,水质满足《地表水环境质量Ⅲ类标准》,为类似煤矿矿井污水处理提供一定的参考。According to the requirements of water pollution prevention and control action plan in Shanxi Province,the chemical oxygen demand,ammonia nitrogen and total phosphorus indexes of mine water pollutants discharged from coal mines should meet the III standard of’surface water environmental quality standard’(GB3838-2002).The existing process of underground sewage treatment station in Ciyaogou Coal Industry cannot meet the requirements of the new standard,and it needs to be upgraded.Taking into account the horizontal extension and future development of coal mine,on the basis of making full use of existing facilities and equipment,the process of’coagulation+sedimentation+labyrinth inclined plate sedimentation+multi-media filtration+ceramic membrane filtration’is adopted.The system after upgrading and reconstruction has advanced technology,strong practicability,reliable technology,can realize automatic control and intensive management,and is economical,reasonable and efficient.The sewage disposal rate is 100%,and the water quality meets the’surface water environmental quality III standard’,which provides certain reference for similar coal mine sewage treatment.
