Description
Technical field
The utility model belongs to sewage disposal regeneration device technique field, is specifically related to a kind of magnetic separating device that mine water underground is processed that is applicable to.
Background technology
Pit water refers in the pit mining process, flows into the water of mine from various sources.This water contacts with coal seam, rock stratum at underground water, add the impact of mankind's activity, a series of physics, chemistry and biochemical reaction have occured, thereby this water water quality has significant coal industry feature: concentration of suspension is high, particle is tiny is difficult to precipitation, and contains used oil, emulsification wet goods organic pollutant.Therefore, the discharging of pit water is contaminate environment not only, and has caused a large amount of wastes of limited water resources and coal dust, and the utilization ratio that improves pit water has double meaning for coal industry development and environment protection.Especially wherein the removal of suspended substance almost becomes requisite important stage in mine water treatment technique.
Suspended matter in pit water mostly is the complex body of organism (coal dust) and inorganics (rock dust), thereby has removed coal dust and just be equivalent to reduce chemical oxygen demand (COD) (COD
cr), so just can reach discharging or reuse standard.And in pit water, suspended substance has generally that content is high, particle diameter is little, settling velocity waits characteristics slowly, if adopt conventional coagulation mode, flco forms difficulty, the coagulating sedimentation weak effect.
At present, the processing of pit water is generally taked is to adopt conventional precipitation technology to process from underground after being evacuated to ground in water again.This processing mode not only can will consume a large amount of energy because of the lifting of pit water, also because the water quality characteristic of pit water and common surface water is widely different, have that content is high, particle diameter is little, settling velocity waits characteristics slowly, therefore required settling tank is more, floor space is large, added amount of chemical is many, and cost is also high.
