Application of resin denitrification in upgrading and transformation of mine water treatment process
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.
