Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to a kind of fruit juice wastewater treatment system embodiment, feature and the effect thereof that the utility model proposes, be described in detail as follows.
See Fig. 1-2, a kind of fruit juice wastewater treatment system, comprises grille well 1, connect preliminary sedimentation tank 2, be connected with equalizing tank 3 by water pump, enter air-floating apparatus 4, air-floating apparatus 4 is connected with automatic medicament feeding machine 13, is separately connected with intermediate pool 5, enters UASB anaerobic reactor 6, be connected with bioselection pond 7 again, be connected with contact-oxidation pool 8 again, enter Aerobic Pond, then enter second pond 9, enter sterilization pool 10 again, sterilization pool 10 is connected with sterilizing unit 11; Preliminary sedimentation tank 2, UASB anaerobic reactor 6 and second pond 9 are connected with sludge thickener 14, and sludge thickener 14 is connected with sludge dewatering equipment 15 by spiral pump, and the supernatant liquor deviate from is back in equalizing tank 3.
Described grille well 1 comprises artificial grid and mechanical grille.
Described air-floating apparatus 4 adopts pressure air-dissolving backflow air supporting, and quantity of reflux is 30% ~ 50%.
Described UASB anaerobic reactor 6 is also connected with gas holder, desulphurization system.
Described contact-oxidation pool 8 is connected with gas blower 12.
Factory effluent gathers and after together artificial grid one mechanical grille slagging-off, enters preliminary sedimentation tank carry out primary deposition, is mainly used in removing the particle suspensions in fruit juice wastewater.Preliminary sedimentation tank goes out water pump and carries to equalizing tank, after equalizing tank carries out the adjustment of the water yield and water quality, utilize submersible sewage pump to be promoted to efficient air-floating apparatus.
Efficient air-floating apparatus mainly removes the emulsification state in sewage, and air-floating apparatus adopts pressure air-dissolving backflow air supporting, and quantity of reflux is 30% ~ 50%.Pressurized dissolved gas flotation device dissolves in air through sharply reducing pressure in a large number under the condition of back pressure, discharges a large amount of micro-water, epigranular, density stabilized microbubble.Microbubble has been polymerized a large amount of small oil droplets, along with microbubble floats up to the water surface, because bubble is small very little to liquid perturbation, can guarantee deoiling effect.Establish running type slag scraper in air-floating apparatus, air supporting coagulating agent adopts polymeric aluminum and polyacrylamide, and adopt automatic medicament feeding machine continuous dosing, sewage together enters reaction agitated pool through line mixer and medicament, then enters air-floating apparatus body.
After flocculation, mixed solution enters in air supporting, and the countless fine supersaturated gas of the sudden pressure reduction release class that suspends in " alumen ustum " and water is combined and floats on the surface of the water formation scum silica frost, and scum silica frost regularly scrapes off by slag scraper.
Efficient air-floating purifier carries out materializing strategy after dosing coagulation, and the gravity flow of waste water after process enters intermediate pool, then by middle water pump lifting to anaerobic treatment equipment---UASB reactor assembly.
UASB reactor is the main equipment in pretreatment system, in waste water, first the macromolecule organic of difficult degradation carries out acidification hydrolization at this, formation is easy to biodegradable low molecule organic matter, polyprotonic acid is converted into unit acid, and be oxidized to ammonia nitrogen, sulfide and carbon monoxide etc., then enter the aerogenesis stage, some unit acid is converted into biogas, and biogas is recycled after entering desulphurization system after being collected by gas holder.
Waste water after UASB reactor for treatment enters after bioselection pond is selected and enters contact-oxidation pool aerobic degradation organic pollutant again.
The ammonia nitrogen of higher concentration can be produced in breaks down proteins process, Aerobic Pond water part is back to hydrolytic tank import, ammonia nitrogen is under aerobic double oxygen alternation condition, by the effect of nitrifier, ammonia nitrogen is converted into nitrite nitrogen, nitric nitrogen by nitrated, and then utilize denitrifying bacteria that nitric nitrogen is converted into nitrogen, thus reach the object of the denitrogenation in waste water.
In bioselection pond, organism complicated in sewage (comprising polysaccharide, fat, protein etc.) is decomposed into organic acid, alcohols by fermenting bacteria.Producing hydrogen at souring stage, producing acetic acid bacteria by tunning organic acid and alcohols metabolism is acetic acid and hydrogen, makes macromolecular substance be degraded to small-molecule substance, makes difficult biochemical solids be degraded to easily biochemical soluble substance, improves the biodegradability of waste water.
Waste water through acidication process enters Aerobic Pond, carries air to carry out aeration in waste water.In water, carbohydrate is that aerobic microbiological provides abundant nutrition, accelerates the metabolism of aerobic microbiological, and under its effect, Organic substance in water is able to effective degraded.Its physiological requirements can be exceeded under aerobic condition and from waste water excess ingestion phosphorus, formed polyphosphate as reserve substance.The remaining active sludge of venting, also namely from waste water, phosphorus is eliminated, sewage after hydrolysis, aerobic treatment flows into second pond, in second pond, suspended matter (microbial film come off) sinks under gravity, sink in the bucket of second pond, enter sludge thickener along spoil disposal pipeline, the water gravity flow so far through settling tank discharge enters sterilization pool, and water quality reaching standard discharges.
Mud in sludge thickener is promoted by spiral pump and enters sludge dewatering equipment, and the supernatant liquor deviate from is back in equalizing tank, carries out reprocessing, and the mud cake of extrusion is transported to appointed place.
The utility model water outlet operative norm: " integrated wastewater discharge standard " (GB8978-1996);
