Abstract: Large amounts of Mine water in China which has been a waste and keeps polluting the environment can actually be reused in production,daily life and ecology.Mine water discharge inGuqiao coal mine which is3500m³/dis characterized by the high concentration of TDS and chloride.The water quality after the existingtreatment is still not up to the drinking-water standards.So it is necessary to add an advanced treatment which is designed asthe process of laminated filters-ultrafiltration -reverse osmosis.The design processes and results are presented in the paper.It shows the quality of treated water can meet the drinking-water standards by the simulation of ROSA.This paper also presents the budget of the project investmentand benefit of the project implementation.
