Abstract:

Based on the hydrogeological conditions of the mine field, the Jiulong coal mine proposes to reuse the high salinity mine water treated underground coal mine to solve the problem of high salinity mine water discharge. According to the proposed water quality index, the experiments treating mine water have been carried out with the process of "coagulation + sedimentation + ultrafiltration".The results show that the water quality indexes of ultrafiltration effluent meet the main water quality indexes proposed.Combined with the existing mine water treatment process of the mine, the "ultrafiltration+disinfection" process is proposed for the deep treatment of underground reuse of mine water to meet the water quality indexes proposed.The advanced treatment process can provide reference for relevant high salinity mine water mines because of saving investment and achieving good results.
