Abstract：To further enhance the level and efficiency of mine water,promote regional economic,ecological and social sustainable development,water quality characteristics,treatment processes,operating results,the reuse direction,and existing problems were investigated for ten mining areas in southern Hebei.The results show that,the Southern Hebei mine water can be classified into three types: suspended solids mine water,hypersalinity mine water and special polluted mine water;the treatment comprises reactive precipitation (clarification),filtration and disinfection treatment process,and the treatment rate is over 90%.At present,the water rate of mine water treatment is still relatively low (about 70%),it is necessary to establish the mechanism of mine water resources utilization,and optimize the allocation of mine water resources.Some of the mine water treatment cost is high,which requires optimization of coagulant,coagulant aids and the dosages,to improve the effect of coagulation and sedimentation,reduce the treatment costs and gradually increase the mine water reclamation rate and economic benefits.
