摘　　要：煤矿废水是造成周边水环境污染的重要因素,通过分析乌兰木伦河石圪台断面水质含量特征、驱动因子和污染趋势,为矿区生态环境建设提供科学依据。从2015年-2021年石圪台断面的历年21项监测数据来看:化学需氧量、氨氮、总磷、高锰酸盐指数、生化需氧量和氟化物6项指标超标率较高,其中高锰酸盐指数、生化需氧量和化学需氧量是影响水质的主要驱动因子;7年期间水质变化趋势显著变好。并结合石圪台断面处的工业排污口、污染源等因素进行溯源分析,对于改善该断面水质具有良好的监督管理作用。Coal mine wastewater is an important factor that causes pollution of the surrounding water environment.By analyzing the water quality content characteristics and driving factors and pollution trend of Shigetai section of Wulanmulun River,the study provided scientific basis for the construction of ecological environment in the mining area.According to 21 monitoring data of Shigetai section from 2015 to 2021,the six indicators of COD,ammonia nitrogen,total phosphorus,permanganate index,BOD 5 and fluoride exceeded the standard at a high rate.Among them,permanganate index,BOD 5 and COD were the main driving factors affecting water quality.The trend of water quality change was significantly better during the seven years.The traceability analysis was carried out in combination with the industrial sewage outlets and pollution sources at the Shigetai section,which had a good supervision and management effect on improving the water quality of the section.
