Technical field
The utility model relates to the Waste Water Treatment of a kind of waste gas water wash that is produced when being used to spray lacquer after clean.
Background technology
When all kinds of Communication Equipments, 3C Product etc. are produced, when being sprayed lacquer, product casing and component etc. can produce a certain amount of waste gas, and this part waste gas is discharging after water wash is clean.But also have a large amount of paint to wait pollution substance through washing the waste water that drenches generation, need this part waste water is handled.Existing treatment process generally adopts the method for deposition+acidication+catalytic oxidation.This method is widely used in paint electrophoresis class waste water treatment, and this technology is comparatively simple, and construction costs is lower.But this technology has some not enough: 1, pre-treatment adopts depositing technology bad to paint type waste water effect, and sedimentation effect is poor, and water outlet is muddy, clearance is low.And paint has tackiness, needs often deposition facility to be cleaned.Though it is 2, adopt acidication technology low as the anaerobic treatment cost, the anaerobism effect is relatively poor, bad to high-molecular weight paint type mass treatment effect.Efficient is very low.And when pretreatment technology is bad, or after for some time facility operation time, a large amount of paint gets into hydrolysis acidification pool and can cause paint that filler is covered, and makes the acidication process failure.
The utility model content
The utility model purpose is to overcome above-mentioned defective, provides a kind of good waste water treatment effect, equipment operation to be difficult for producing the water that sprays paint that paints covering filler problem and drenches cabinet spray treatment system.
The technical scheme of the utility model is: design a kind of water that sprays paint and drench cabinet spraying Waste Water Treatment; Comprise dissolving, air flotation pool, equalizing tank, middle pond, UASB pond, Aerobic Pond, coagulation reaction tank and the settling tank of being with air compressor machine, the water outlet of said dissolving is connected with the dissolved air release that is positioned at said air flotation pool; Said equalizing tank is connected with said air flotation pool through sewage pump; On said air flotation pool, be provided with slag scraper, the water outlet of said air flotation pool is connected with middle pond through pipeline; The pond is connected with said UASB pond through force (forcing) pump in the middle of said, in said UASB pond, is provided with triphase separator; The water-in of said UASB pond water outlet and said Aerobic Pond joins, and is provided with aeration head in the bottom of said Aerobic Pond, above said aeration head, is provided with the combined stuffing parts; The water outlet of said Aerobic Pond and said coagulation reaction tank water-in join; The water outlet of said coagulation reaction tank and the water-in of said settling tank join.
As improvement to the utility model, be provided with sludge outlet in the bottom of said settling tank, said sludge outlet and sludge sump join.
As the improvement to the utility model, the water outlet and the clean water basin of said settling tank join.
As the improvement to the utility model, said sludge sump is connected with press filtration pump and plate-and-frame filter press.
As the improvement to the utility model, said dissolving joins through the water outlet of fresh water pump and air flotation pool.
The utlity model has following advantage:
1, improves the Wastewater Pretreatment effect through newly-increased air-flotation system, major part paint and insoluble separating organic matters are come out.Can reduce the concentration that waste water gets into preceding COD of biochemical system and all kinds of macromolecule organics greatly.And behind the separating most paint, can effectively prevent the mikrobe surface of sticky paint attached to biochemical system.The life cycle and the maintenance intervals of biochemical system have been prolonged greatly.
2, through using the UASB anaerobic reactor to replace traditional hydrolysis acidification pool.Improved the anaerobism effect.And UASB do not have traditional filler, can not paint the problem that reduces anaerobism efficient attached to filling surface.
