摘　　要：在对塔拉壕煤矿项目进行环境影响评价中,为了解决该煤矿矿井水处理站出水中氨氮及总氮不能达标等现状问题,分析了矿井水水质及脱氮工艺,研究了针对硝态氮及氨氮的两种大孔树脂的脱氮基理及工艺参数,提出了以《地表水环境质量标准》(GB 3838-2002)中Ⅲ类标准为目标的提标改造方案。通过对提标改造方案的实施,矿井水处理站出水水质中氨氮及总氮可稳定满足标准要求。在此基础上,分析并总结了含氮矿井水处理工艺提标改造的关键问题,以期为矿井水中氨氮及总氮不能达标的煤矿企业提供指导。In the environmental impact assessment project of Talahao Coal Mine,it's found that,the ammonia nitrogen and total nitrogen in the effluent from the coal mine water treatment station failed to meet the standards.So,the mine water quality and denitrification process were analyzed,the nitrogen removal matrix and process parameters of two macroporous resins for nitrate nitrogen and ammonia nitrogen were studied.The upgrading measures based on the Class III standard in the Surface water Environmental Quality Standard(GB 3838—2002)were put forward and implemented,after which,the effluent quality of the mine water treatment station was kept standards-compliant.On this basis,the key problems of high total nitrogen index in mine water were analyzed and summarized,to provide guidance for coal mine enterprises facing such problems.
