Experimental Study On The Utilization Technology Of Drainage Pit Mine Water Of HaiZhou Open Pit

For a long time, the drainage pit mine water of HaiZhou open pit can't be used fully, and large water only be drained as waste water which squanders water greatly. This thesis studies the utilization problems of the drainage pit mine water in view of this case. According to the mine water quality of the drainage pit, a technological process which is composed of coagulation, settling, filtration, electrodialysis and disinfection units is determined from the theory analysis and the technical comparison, and a lot of theory analysis and experiments study have been carried out mainly for the important influence factors of each treatment unit.In coagulation stage, the experiments of beaker stir decide the optimum coagulant, the optimum dosage and PH of the coagulant. In settling stage, the experiments of settling bar analyze the influence of settling period to settling effect. The mine water can meet the production water quality standards of mining area after the two units, if through electrodialysis removing salt and disinfection, it can achieve the drinking water quality standards.The study shows that the mine water of the drainage pit can utilize after treatment, and the treatment pattern of the mine water can set an example to the utilization of the mine water in FuXin mining area.
