Description
Technical field
This utility model relates to the technical field of environmental treatment, is specially a kind of lightweight biofilter.
Background technology
At present conventional BAF sewage higher for concentration of suspension or the higher sewage of COD concentration then cannot directly use, can use after needing raw sewage is carried out pretreatment, be mainly manifested in advanced treating or the float sewage less than 60mg/L that can only apply to sewage.
This device is current from top to bottom, inside fill out lightweight suspension biofilter material, float in sewage, colloid are had and effectively adsorbs, retain, use venturi jet-flow aeration, water is carried out efficient oxygenation, utilize absorption in the microorganism of lightweight suspension biofilter material, remove the Organic substance in water, ammonia nitrogen pollutant, the dirty water purification of final realization.
Summary of the invention
For the problems referred to above, this utility model provides a kind of lightweight biofilter, and it is vertical type cylinder shape flat barrel shape structure.
The technical solution of the utility model is as follows: it includes equipment barrel 1, perforation cloth tank 2, water inlet 3, baffle plate 4 is carefully stitched in high density bar shaped, lightweight biologic packing material 5, jet aeration pump 6, venturi ejector 7, efficiently oxygenation nozzle 8, baffle bucket 9, filter screen 10, annular wrapping wire catchments perforated pipe 11, charging door/discharge port 12, backwash water inlet 13, backwash discharge outlet 14, outlet 15, water sucking mouth 16, efficiently oxygenation nozzle 8 pipeline is connected with venturi ejector outlet 7, venturi ejector 7 import is connected with jet aeration pump discharge, jet aeration pump 6 import pipeline is connected with water sucking mouth 16.Backwash water inlet pipeline with back-washing equipment be additionally set be connected, backwash water is discharged outside entire body by backwash discharge outlet 14.
This device uses water intake mode from bottom to top, the jet-flow aeration of venturi+high efficiency nozzle, high density bar shaped carefully to stitch baffle plate water distribution, use lightweight suspension biofilter material to catchment as bio-carrier, the annular wrapping wire perforated pipe that catchments, gas clear water backwash；Successfully overcome the weak point of the most conventional BAF.
Using top-down waterpower to flow, it is adaptable to the sewage of high suspended matter, float concentrates absorption to be carried out filtrate from bottom to top on filtrate top, beneficially clear water simultaneously.Outlet is arranged on bottom of device, uses flow by gravity water outlet, and therefore water inlet can enter in device with high head gravity flow.

Fig. 1 is front view structural representation of the present utility model.
Description of reference numerals: equipment barrel-1, perforation cloth tank-2, water inlet-3, high density bar shaped carefully stitch baffle plate-4, lightweight biologic packing material-5, jet aeration pump-6, venturi ejector-7, efficient oxygenation nozzle-8, baffle bucket-9, filter screen-10, annular wrapping wire catchment perforated pipe-11, charging door-12, backwash water inlet-13, backwash discharge outlet-14, outlet-15, water sucking mouth-16.
Detailed description of the invention
A kind of lightweight biofilter, it includes equipment barrel 1, perforation cloth tank 2, water inlet 3, baffle plate 4 is carefully stitched in high density bar shaped, lightweight biologic packing material 5, jet aeration pump 6, venturi ejector 7, efficiently oxygenation nozzle 8, baffle bucket 9, filter screen 10, annular wrapping wire catchments perforated pipe 11, charging door 12, backwash water inlet 13, backwash discharge outlet 14, outlet 15, water sucking mouth 16, efficiently oxygenation nozzle 8 pipeline is connected with venturi ejector outlet 7, venturi ejector 7 import is connected with jet aeration pump discharge, jet aeration pump 6 import pipeline is connected with water sucking mouth 16, backwash water inlet pipeline with back-washing equipment be additionally set be connected, backwash water is discharged outside entire body by backwash discharge outlet 14.
Sewage initially enters device perforation cloth tank 2 by water inlet, aperture by cloth tank 2 sidewall of boring a hole, ensure that sewage is arranged in apparatus surface uniformly, when sewage passes through lightweight biologic packing material 5, utilize Absorption Growth in lightweight biologic packing material microorganism fungus kind decomposition, be aided with jet aeration pump 6 again, venturi ejector 7, efficient oxygenation nozzle 8 form jet-flow aeration system and carry out oxygenation, making sewage be purified, the sewage after purification is collected outside discharger finally by the annular wrapping wire perforated pipe 11 that catchments.Current top in order to prevent efficient oxygenation nozzle from spraying mutually is collided and is crossed, and affects oxidation effect, and the heart arranges baffle bucket 9 in a device.
After device long-play, the microbes of the float and growth that were trapped in lightweight biologic packing material 5 surface gets more and more, eventually resulting in water outlet can become cloudy, muddy reason is primarily due to the aging biological diaphragm being made up of microorganism and float that lightweight biologic packing material 5 comes off and is mixed into final outflow water.It is thus desirable to periodically lightweight biologic packing material 5 is carried out backwash, because this device current are top-down, therefore float, microorganism is concentrated mainly on lightweight biologic packing material 5 middle and upper part, therefore use high-velocity flow from bottom to top that lightweight biologic packing material 5 is carried out backwash, the aging biological diaphragm of lightweight biologic packing material 5 is made to come off, finally with backwash water from backwash discharge outlet 14 discharger.
Using jet aeration pump, venturi ejector, efficient oxygenation nozzle composition jet-flow aeration system to carry out oxygenation, oxygen-transfer efficiency is higher than nanopore device efficiency, as a example by air source, at 1 atmosphere pressure, 5.0 meters of depth of waters, micro-pore aeration oxygenation is 15～20%, and jet-flow aeration is about 30%.Additionally efflux aerator power source is from water pump, and micro-pore aeration oxygenation power resources are in blower fan, in order to reach same oxidation effect, blower fan either in investment, operating cost all cannot be comparable with water pump or run the aspect such as noise, later maintenance maintenance.Jet pump and venturi ejector are arranged on outside device；Efficiently oxygenation nozzle is fixed on above device outer wall, is circular layout；Jet-flow aeration system overhaul is easy to maintenance, does not haves the blockage problem of microporous aeration device.
Using lightweight suspension biofilter material as bio-carrier, the density of this filtrate is very close to the density of water, in water, lies substantially in suspended state, does not therefore worry that filler filling is uneven.Filler uses light type high-molecule polymer (EPS) to make, and wearability is good, Stability Analysis of Structures, and water absorption rate is relatively low, and rounded cystose is placed in water for a long time and does not haves broken situation.
Device top spreads a floor height density bar shaped and carefully stitches baffle plate, and thin seam width determines according to filler specification.Act on a water distribution uniformity, water outlet；When effect two prevents clear water backwash, filler outflows with water.Comparing with porous plate+water cap, baffle plate processing technique, installation portion sequence are simple, reduced investment, and general employing plastic plate makes, and does not haves blockage problem.
Above-described embodiment is this utility model preferably embodiment; but embodiment of the present utility model is also not restricted to the described embodiments; other any without departing from the change made under spirit of the present utility model and principle, modify, substitute, combine, simplify; all should be the substitute mode of equivalence, within being included in protection domain of the present utility model.
