Pond, sludge are discharged into sludge concentration tank.
The advantages and positive effects of the present invention are:
1. the present invention uses coagulation and the dual preconditioning technique of air bearing, major part SS in waste water is eliminated, raw water is reduced
Turbidity and coloration, while also reducing COD, BOD, TN and TP, greatly reduce the load of subsequent biosystem.
2. process coating waste-water and sanitary sewage that the present invention uses UASB to combine with SBR, degradable major part
Organic matter improves the biodegradability of waste water；SBR process operation mode is flexible, and become reconciled feeding process of anaerobism alternately occurs, sludge age is short,
It is active high, substantially increase the removal efficiency of TN and TP in waste water.
3. the present invention uses active carbon filter plant, it is further processed, goes remaining in water removal to relatively clear
The substances such as particle, bacterium, microorganism make to be discharged qualified discharge or reuse.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of a kind of coating waste-water and sewage treatment unit of the invention
Specific embodiment
The invention will be further described with reference to the accompanying drawing and by specific embodiment, and following embodiment is descriptive
, it is not restrictive, this does not limit the scope of protection of the present invention.
As shown in Figure 1, a kind of coating waste-water and sanitary sewage Integrated Processing Unit, including by pipeline it is sequentially connected into
Water pump 1 (11), collecting-tank 3, coagulative precipitation tank 4, air pressure pump 5, pressure volume pot 6, flotation tank 10, conditioning tank 12, UASB15,
SBR18, micro porous aeration head 19, compressed air 20, intermediate pool 21, active carbon filtering ponds 22, sludge concentration tank 23 (26), sheet frame
Filter press 25 (28).Coating waste-water enters collecting-tank 3 under the action of intake pump 1, then precipitates through coagulative precipitation tank 4 laggard
Enter flotation tank 10, removes a large amount of solid suspension and colloidal substance；Enter conditioning tank 12 later, sanitary sewage is through intake pump 11
Into conditioning tank, mixed with by pretreated coating waste-water；The water outlet of conditioning tank 12 enters the progress anaerobism of the pond UASB 15 and disappears
Change, the organic matter in sewage of degrading；UASB15 water outlet enters SBR18, and the bottom SBR18 is equipped with micro porous aeration head 19, provides oxygen
It is sufficiently mixed waste water with sludge, degradation of organic substances, water outlet enters intermediate pool；Intermediate pool water outlet enters active carbon filtering ponds
22, it further purifies, produces water qualified discharge or reuse.
The precipitating generated after 4 dosing of the coagulative precipitation tank flocculation is discharged into sludge concentration tank 26, enters plate through sludge pump 27
Frame filter press 28, effluent recycling to collecting-tank 3, mud cake outward transport；The sludge that other each units generate is discharged by spoil disposal pipeline
Sludge concentration tank 23 enters plate and frame filter press 25, effluent recycling to conditioning tank 12, mud cake outward transport through sludge pump 24；
10 working method of air-floating apparatus is that the water outlet of coagulative precipitation tank 4 enters pressure air-dissolving tank 6 through air pressure pump 5,
It is passed through air into dissolving 6 simultaneously, opening pressure reducing valve 7 makes gas and water enter flotation tank, a large amount of fine gas bubbles is generated, in waste water
Substance similar in density and water attaches to bubble, is floated to wastewater surface, enters scum trough 8 through Slag Scraping Device 9, and in scum trough 8
Sludge be discharged into sludge concentration tank 23；
The characteristics of conditioning tank 12 has regulating pondage, uniformly walks water, flotation tank water outlet enters conditioning tank, lives simultaneously
Sewage enters conditioning tank by intake pump 11 and mixes with by pretreated coating waste-water.
The UASB15 is made of sludge reaction area, gas-liquid-solid three-phase separator 13 and gas chamber three parts.Have one in bottom
A high concentration, the Sludge Bed of high activity, sewage enter UASB15 from bottom to top, come into full contact in base sludge bed with sludge,
Organic substance in water matter becomes biogas by anaerobic fermentation.Biogas constantly merges in uphill process forms biggish bubble, sludge,
Water, biogas enter three phase separator 13 together, when biogas encounters the reflecting plate of separator lower part, are folded to the surrounding of reflecting plate, so
Water layer is passed through afterwards and enters gas chamber, concentrates on the export of gas chamber conduit 14, solid-liquid mixed liquor is by being reflected into three phase separator 13
Settling zone, the sludge in sewage flocculates, and particle is gradually increased, and is settled under the effect of gravity, and Sludge Bed is slid back to.Processing
Sewage afterwards is discharged from upper right side, and the sludge overflowed from sludge settling area top is discharged into sludge concentration tank 23.
The SBR18 working method is that UASB15 water outlet enters SBR18 by elevator pump 16, and sewage level reaches in pond
After setting height, compressed air 20 and 19 equipment of micro porous aeration head provide intermittent oxygen, are sufficiently mixed sewage with sludge,
Organic substance in degradation sewage, treated, and sewage enters intermediate pool 21, and sludge is discharged into sludge concentration tank 23.
The treatment process of a kind of coating waste-water and sanitary sewage includes such as the next stage:
1. pretreatment stage: coating waste-water flows into collecting-tank under the action of intake pump, later by the waste water in collecting-tank
Be introduced into coagulative precipitation tank, be added flocculant, by gravitational settling removal waste water in pollutant, finally by flotation tank into
One step removes SS, TP.
2. biological treatment stage: water outlet on last stage enters in UASB, carries out anaerobic reaction, and it is useless can to remove coating
Most of organic matter in water；Sewage is discharged from the upper port of UASB, and boosted pump enters in the pond SBR, and micropore is equipped in this device
Aeration head, can intermittent offer oxygen, be sufficiently mixed sewage with sludge, degradation of organic substances matter, while aerobic in the pond SBR
Replace generation, further denitrogenation dephosphorizing with anaerobic processes.
3. active carbon filtration stage: the water pumping in above-mentioned intermediate pool being gone out, is filtered by active carbon, will be given up
Some SS, colloidal substance, macromolecule organic, microorganism in water etc. further remove, and finally water outlet reaches sewage discharge mark
It is quasi-.
4. the Treatment of Sludge stage: flocculation medicament will be added in coagulative precipitation tank, flocculates, generate a large amount of sediment,
Sediment is discharged into sludge concentration tank by mud discharging mouth, is dehydrated under the action of plate and frame filter press, and the filtrate of generation flows back into
Collecting-tank, mud cake outward transport；The sludge that other each units generate is discharged into sludge concentration tank by spoil disposal pipeline, in the work of sludge pump
It enters plate and frame filter press under to be dehydrated, the filtrate of generation is back to conditioning tank, mud cake outward transport.
The above is the embodiment of the present invention, and it's not limited to that, all in spirit of the invention and appended claims
Same replacement, change and modification for being done within the scope of etc., should all be included in the protection scope of the present invention.
