Abstract
Aimed at an improved treatment efficiency of mine water and reduced cost of processing,this paper introduces the treatment of mine water by combining magnetic field with coagulating sedimentation and the analysis of the coagulation effects of PAC solution under non-magnetization and the coagulation effects of PAC solution under magnetization condition or water samples under magnetization condition.The results show that adding the PAC solution dosage of 25 mg/L gives a turbidity removal rate of 86%.Both magnetization treatment of water samples and PAC solution have a positive effects on mine water coagulation,with the latter more obvious.Magnetic field intensity of 0.2 T and magnetizing time of 8 minutes produce the best effect of magnetization PAC solution on the coagulation of the mine water,resulting in the highest turbidity removal value,4.5% higher than does non-magnetization.The study proves that magnetization coagulation process enables an effective purification of mine water in a shorter period of time.关键词
