The utility model discloses the waste water treatment flow is simple, and treatment cost is lower, and is easy and simple to handle, but goes out the water retrieval and utilization, has effectively protected the water resource, has alleviated colliery lack of water current situation.
Description
Technical field
The utility model belongs to technical field of sewage, is specifically related to a kind of coal mine Waste Water Treatment.
Background technology
Technique of Coal Mine Drainage is the underground water near mining area institute's mining coal seam and development roadway, sometimes also containing a small amount of surface water infiltrated, when pit water flows through coal-face and tunnel, because being subject to Mankind action, the suspended particles such as coal dust can be brought into, in addition, pit water also can be subject to emulsion and the excremental slight pollution of staff of coal excavation apparatus in down-hole mining process, composition mainly suspended substance, soluble inorganic matter and a small amount of grease of coal mine waste water.General suspended substance and colourity higher, total plate count exceeds standard, and COD, BOD slightly exceed standard.
China's coal-mine mine wastewater treatment technique functions starts from late 1970s.The purification of Mine Water Transacting Technology the earliest requires it is qualified discharge.Usual employing precipitation or coagulation, precipitation process technology.But along with the anxiety of mining area water, reuse after coal mine water treatment is seemed very necessary.Membrane technique is further treatment technique, wherein especially with ultrafiltration membrane technique, there is water flux large, crushing is little, can effectively remove the features such as suspended substance, colloid and bacterium, more and more come into one's own, but the fouling membrane in operational process has contained that it further develops, how to prevent and treat fouling membrane, process coal mine waste water reaches the focus that recycle water standard has become research efficiently.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and provide a kind of coal mine Waste Water Treatment, the utility model is reasonable in design, treatment effect good, and can effectively process coal mine waste water, water outlet reaches recycle water standard.
For achieving the above object, the technical solution adopted in the utility model is: a kind of coal mine Waste Water Treatment, it is characterized in that by retention basin, line mixer, Hun Ning ?ultrafiltration membrane pool, clean water basin connected to form by pipeline and valve successively, wherein: the pipeline that retention basin is connected with line mixer be provided with lift pump Hun Ning ?the pipeline that is connected with clean water basin of ultrafiltration membrane pool be provided with suction pump and backwashing pump, the pipeline that lift pump is connected with line mixer is provided with volume pump.
Wherein: volume pump is communicated with poly-ferric chloride NaOH solution tank NaOH, the poly-ferric chloride in poly-ferric chloride NaOH solution tank NaOH is added in waste water, in line mixer, carry out hybrid reaction.
Described Hun Ning ?agitator and submerged hollow fibre membrane module in bioreactor are housed in ultrafiltration membrane pool.
Hun Ning ?be provided with sludge pump and sludge sump bottom ultrafiltration membrane pool, sludge sump is connected with belt filter press.
The utility model compared with prior art has the following advantages:
One, the water outlet after process can reuse, pit water is fully utilized, economizes on resources, decrease environmental pollution;
Two, core process of the present utility model be Hun Ning ?the organic coupling of ultrafiltration membrane technique, effectively slow down the pollution of ultra-filtration membrane, the flco that coagulating is formed is attached to the surface of ultra-filtration membrane, form flco layer, decrease contacting of pollutent and ultra-filtration membrane, decrease film surface pollution and fenestra pollutes odds; Flco layer loosens, and adopts back flushing to remove; Flco layer has pre-filtering effect, improves effluent quality.
Three, the utility model is by the experimental study of system, determines that poly-ferric chloride is best coagulating agent, and the flco size of formation more greatly and more loose; Hun Ning ?the optimum coupling of ultra-filtration membrane coupling to select be that mixed solution after coagulation completes carries out ultrafiltration, now effluent quality is good, and fouling membrane is lighter.
Four, the utility model is reasonable in design, treatment effect good, effectively can process waste water of mine, and water outlet can coal washing water be done in reuse, road sprays water etc.
