Mine water treatment equipment

In the process of coal mining, groundwater comes into contact with coal seams and rock layers, and a series of physical, chemical, and biochemical reactions occur due to human activities. Therefore, the water quality has significant characteristics of the coal industry: the suspended solids content of mine water containing suspended solids is much higher than that of surface water, and the sensory properties are poor; And the suspended solids contained have small particle size, light specific gravity, slow settling speed, and poor coagulation effect; Mine water also contains organic pollutants such as waste engine oil and emulsified oil. The total ion content in mine water is much higher than that in general surface water, and a large part of it is sulfate ions. Mine water often has a particularly low pH value and is often accompanied by a large amount of ferrous ions, which increases the difficulty of treatment.

Mine water treatment usually adopts the treatment process of "advection sedimentation+coagulation sedimentation+multi-media filtration" according to the requirements of discharge indicators. If the effluent meets the reuse or surface discharge standards, ultrafiltration/nanofiltration/reverse osmosis units need to be added after the multi-media filter for deep treatment.

Mine water can be treated for underground reuse and surface discharge standards.
