Description
Technical field
The invention belongs to mine wastewater processing technology fields, and in particular to a kind of coal mine water and/or coal washing waste water
Processing method.
Background technique
Coal mine water, gangue, coal mine gas are the typical three wastes of coal mining industry.Coal mine water, which refers to, to be adopted
During coal, all water for penetrating into down-hole mining space also have the spy having a large capacity and a wide range containing the surface water penetrated on a small quantity sometimes
Point.It is counted according to Coal Industry Society (CIS), it is contemplated that arrive the year two thousand twenty, coal in China exploitation total amount is up to 4,000,000,000 tons, generates mine water 60
Billion cubic meter.Coal mine water mainly contains suspended matter, inorganic salts, heavy metal etc., will be to surrounding body, soil if direct emission
Earth, people and animals cause damages.Therefore, coal purification of mine drainage and water resources comprehensive utilization become the new emphasis of industry.
Coal washing waste water include wet type coal washing generate waste water, the black water of coal preparation plant, coal-burning power plant ground flushing waste water
Deng being all the mixture of water and fine breeze, be mainly characterized by turbidity height, particulate size is thin, and solid particles surface mostly band is negative
Charge, the repulsion between homophilic charge make these particles keep dispersity in water, are influenced by gravity and Brownian movement；Due to
Interaction (such as adsorb, dissolve, chemical combination) in black water between solid particle interface, keeps the property of coal washing waste water quite multiple
It is miscellaneous, not only with the property of suspension, also with the property of colloid.Coal washing waste water is difficult nature clarification due to the above reasons, and
And supernatant is still the black liquor with suspended matters such as a large amount of coal slimes to this kind of waste water after precipitation, wherein processed containing coal separation
The harmful substances such as various additives and heavy metal in journey.The below standard discharge of a large amount of coal washing waste water, causes water pollution, river
Silt up, coal slime loss, also results in great water resource waste.There is no strictly distinguish above-mentioned coal mine water for most of coal mines
And/or coal washing waste water, but mix and handled into sewage treatment plant.
The conventional processes of coal mine water and/or coal washing waste water are " coagulating sedimentation+filtering " at present, using coagulant
(aluminium polychloride etc.) and high polymer coagulant (polyacrylamide etc.) and coal slime particle or coal slime colloid contact action neutralize coal
Low-surface-energy drops in the electrical property on mud surface, so that coal slime particle coagulation precipitates.The technique can remove a part of big coal particles,
Suspended matter, but there are still many drawbacks: coagulant, flocculant usage are big, and medicament is costly；Medicament has equipment certain
Corrosivity, once and flocculant excessive addition, subsequent advanced treating will be caused to seriously affect；Tiny particles content is removed
Effect is undesirable, is easy to cause Flushing nozzle fouling blockage；Effluent quality fluctuation is big, can not meet discharge and reuse standard etc..
ZL201611025222.4 discloses a kind of method of coal-contained wastewater processing, passes through one preliminary sedimentation tank of design and a tubular type
Microfiltration membrane system removes granule foreign tiny in waste water.But tube microfiltration membrane 1.5~4.0bar of system running pressure, according to
Alleviate fouling membrane by high surface velocity, simultaneously, tube microfiltration membrane system is easily contaminated for operation energy consumption height, and cleaning frequency is high.And it manages
The filter membrane system that declines can only remove tiny particles content, not can be removed various additives, coloration and heavy metal etc., and producing water water quality is low,
It is unable to satisfy high-quality water demand.
Summary of the invention
