This composite purification device essence is formed by multiple barrel jacket string, the biopurification process of sewage concentrates in structures and completes in the lump by it, eliminate numerous and diverse equipment such as prior art anaerobic pond, anoxic pond and secondary sedimentation basins, have save land, energy-conservation, reduce the advantage such as construction investment and working cost.
The aerating system of composite purification device is arranged at the lower edge of central reaction cylinder and decline cyclone ring respectively, surrounds circular with high density polyethylene(HDPE) micropore aeration pipe along barrel.The vertical web plate of cyclone ring is substantially vertical with coming from the water (flow) direction that mud return line second exports.
The present invention solves the technical scheme that above-mentioned second technical problem takes: a kind of method applied integrative aerobic particle sludge composite purification device and dispose of sewage, technical process comprises: processed sewage is divided into two-way to export from first of mud return line the outlet and second entering composite purification device pond, wherein the sewage of 50% sprays into taper mud accumulation area by body lower end, pond, spout flow rate control is between 1.5m/s ~ 2.0m/s, after mixing with pool bottom sludge, be subject to vertically to water, sweeping along of gas two phase flow, centrally reaction tube moves upward, upper edge through the horizontal web plate of reaction tube that arranges layer by layer therefrom heart reaction tube enters decline cyclone ring region, the sewage of another 50% tangentially flows into along external annulus on the top of decline cyclone ring, drives the mixed solution from central reaction cylinder to flow downward through the vertical web plate rotation of cyclone ring with the form of helical flow, sewage after purifying treatment, flow out from sidewall deposit exhalant region, excess sludge is deposited in taper mud accumulation area, discharges through mud discharging pipe.
Main technological features of the present invention is as follows:
1, the microbe species in mud is various, particularly be deposited in the mud of bottom the microorganism growing multiple generation cycle length and have specific function, the multiple-microorganism floras such as such as nitrification bacteria, Denitrifying Phosphate Accumulating Organisms aerobic denitrifying bacteria and ANAMMOX bacterium, define the cluster advantage of biopurification, sewage enters from bottom jet, entrain a large amount of microbially decontaminate to decompose, accelerate biochemical process.
2, after sewage enters at the bottom of pond, flowing through central reaction cylinder and decline cyclone ring successively, repeatedly experiencing the working cycle of anaerobic-aerobic-anoxic-aerobic, create good nurturing an environment, because the organic concentration of fresh sewage is very high, the floras such as polyP bacteria fermentation and acid bacterium collaborative under, by abundant easy degraded voltaile fatty acid VFA sbe converted into poly-β hydroxybutyric acid PHB, polyP bacteria and Denitrifying Phosphate Accumulating Organisms bred rapidly, becomes the dominant microflora of composite purification device, be conducive to the simultaneous nitrogen and phosphorus removal at degraded BOD.
Solid 3, the biochemical reaction of sewage purification be gas-water-phase reaction, reactant such as organism, oxygen deliver to reaction interface by mass transfer, and resultant of reaction also will transfer out through mass transfer; Mass transfer velocity often becomes the bottleneck of conditioned response process, and the utilization of central tube fluidization technology, make central tube flow velocity reach 50mm/s, improve rate of mass transfer, biochemical reaction speed is significantly improved.Web plate is to the strengthening of hydraulic shear, and make microbial film and granule sludge remain very high biological activity, everything all improves the task performance of cleaner.
4, the adding of web plate, creates condition for microorganism adheres to breed and form microbial film on web plate, and generally, reactor runs 3 ~ 5d, and microorganism can biofilm and form microbial film; In microbial film, due to the depth of penetration only 100 ~ 150 μm of oxygen, and the avidity of ammonia oxidation bacteria AOB and oxygen is far above NOB NOB, this is just for nitrosification in microbial film creates condition and facilitate short-cut nitrification and denitrification, test shows, the activity of suppression NOB NOB is the key of short distance nitration steady running, except DO, free ammonia FA concentration (0.6 ~ 5mg/l) is dissociated nitrous acid FNA(0.02mg/l) and low water temperature (<15 DEG C) condition NOB all can be made to be suppressed
Biochemical practice reaction proves: microorganism hungry-be satiated with food not only is conducive to stablizing of granule sludge toward the operating mode of complex Alternating under, and can play its purification efficiency to greatest extent.At the bottom of pond and the decline cyclone ring top creation of forms of intaking respectively microbial starvation---the environment of reciprocation cycle of being satiated with food, not only increases purification efficiency, also can reduce excess sludge discharge amount.Because the mud of web plate microbial film and granule sludge is all very long for age, longer mud impels microorganism to experienced by the endogenous respiration course of own biological oxidation age, excess sludge is reduced, reduces sludge yield from source.
5, in decline cyclone ring, sewage injects Chi Tihou with tangential direction, by drive mixed solution with the form rotary motion under screw; Because rotary centrifugal force is different with grain diameter size, this will facilitate the further coalescence of discrete small-particle, and the further densification of granule sludge is not only conducive to dirty water clarification, also help granule sludge and remove the separation of impurities in water.
Research shows, the compound of the motion of decline circulation formation potential barrier and swirling motion, make particulate matter in water automatically away from limit wall in center set, this just creates good hydrodynamic conditions for arranging sidewall deposit exhalant region, also make water outlet be convenient to precipitate and separate, maintain good SS and precipitate removal condition.
Beneficial effect of the present invention mainly contains:
1, the organic composite of microbial film and granule sludge, increases microbial population and biomass, and improve the removal ability of pollutent, shorten hydraulic detention time, Economization on land takies 30%, saves construction costs 20%;
2, effectively can reduce excess sludge production, and then reduction sludge treatment takes about 10% with disposing;
3, recombining process is without the need to sludge reflux, conserve energy can consume 10 ~ 20%.
The present invention integrates biochemical reaction and precipitate and separate, eliminates the construction of second pond; Granule sludge low with biomembranous water ratio, mud, than great, only between decline cyclone ring and shell, arrange the demand that namely a deposit exhalant region meets mud-water separation, does not need separately to build second pond, saves soil and construction costs.
