Detailed description of the invention

In conjunction with accompanying drawing, this utility model is described in further details.

As it can be seen, a kind of Wastewater from Pig Farm processing means, described Wastewater from Pig Farm processing means includes UASB reactor 1, preliminary sedimentation tank 2, Buffer Pool 3, regulating reservoir 4, hydrolytic tank 5, Aeration tank 6, second pond 7, flocculation basin 8, sedimentation tank 9, sterilization pool 10, dirt The condensing pond of mud 11 and equipment room 12, UASB reactor 1 lower end is connected with Wastewater from Pig Farm sump 14 by pipeline, and UASB is anti- Answering device 1 to connect also by pipeline pond 11 condensing with preliminary sedimentation tank 2 and mud respectively, preliminary sedimentation tank 2 is structure as a whole with Buffer Pool 3, and Communicating, preliminary sedimentation tank 2 is connected by pipeline pond condensing with mud 11, and Buffer Pool 3 is connected with regulating reservoir 4 by pipeline, and regulating reservoir 4 leads to Piping is connected with hydrolytic tank 5, and hydrolytic tank 5 is connected by pipeline pond 11 condensing with Aeration tank 6 and mud respectively, and Aeration tank 6 leads to Piping is connected with second pond 7, and second pond 7 is connected by pipeline pond 11 condensing with flocculation basin 8 and mud respectively, and flocculation basin 8 leads to Piping is connected with sedimentation tank 9, and sedimentation tank 9 is connected by pipeline pond 11 condensing with sterilization pool 10 and mud respectively, described sterilization Pond 10 and the condensing pond of mud 11 are further connected with delivery pipe, and the quantity of the delivery pipe that sterilization pool 10 is connected to is one, the condensing pond of mud 11 The quantity of the delivery pipe being connected to is two, is provided with Roots blower in described equipment room 12, and Roots blower is by pipeline respectively Connect with hydrolytic tank 5 and Aeration tank 6.

Embodiment: owing to water inlet biogas slurry water quality is the most unstable, COD is at more than 1500mg/L, if such water quality enters Aerobic treatment unit will consume medicine by oxygen consumption in a large number, utilizes the processing mode of UASB three phase separator strictly anaerobic by water treatment To a certain extent；Preliminary sedimentation tank 2 can remove in waste water can hypostasis and floating thing, waste water after just heavy, the most removable can hypostasis and The 50% of floating thing, the 20% of BOD, by removing unit mass BOD or solids calculating, preliminary sedimentation tank 2 is to save the most Purifying step, the sewage higher for float the most easily uses preliminary sedimentation tank 2 pretreatment, hydraulic loading rate typically take 0.6～ 1.2m3/ (m2 h) is advisable, and sewage is mainly derived from biogas slurry, and the suspended particulate matter in sewage is a lot, if after being directly entered Continuous biochemical system, can increase the process load of subsequent processing units, affect treatment effect, it even can be made not run well, Pretreated sewage enters aftertreatment systems and processes, and the process at this kind of waste water is concentrated mainly in dephosphorization, biochemical The dephosphorization clearance of effect has reached the limit, but too high phosphorous index does not reaches technological requirement by subsequent treatment to the greatest extent, it is necessary to giving birth to Change system front end and the pretreating process of dephosphorization is set, use and add PAC and PAM flocculation sediment at preliminary sedimentation tank 2, generating containing phosphatization While compound from system precipitation of phosphorus；Sewage is also accident pool at the regulating reservoir 4 regulating water quality water yield, regulating reservoir 4, has following work With: 1, preliminary sedimentation, separation；2, regulating water quality, enables water quality to equalize, beneficially next process；3, regulating pondage, If water inlet is not at the uniform velocity, this pond just can regulate；4, the effect of accident buffering can be realized, if place's science and engineering below There is little fault in sequence, and waste water can here do storage of short duration, play the effect of buffering, is unlikely to be that production process is because of waste water Can not get rid of and shut down；In hydrolytic tank 5, utilize the anaerobe decomposition to macromolecular compound, held concurrently more difficult in sewage Property microorganism and aerobic microbiological decompose macromolecular compound be decomposed into micromolecular compound, the Organic substance of non-the dissolved is cut Stream is progressively converted into the Organic substance of the dissolved, to improve the removal effect to COD of the follow-up aerobic reaction facility, weakens and even eliminates Some organic compound is to the suppression of nitrifier in aerobic reaction facility, when Organic substance in water is labyrinth, hydrolysis acidification bacterium C-C in organic molecule is opened by the H+ and-OH utilizing H2O to ionize, and one end adds H+, one end addition-OH, can be by long-chain Be hydrolyzed to short chain, side chain becomes straight chain, circulus becomes straight or branched, improves the biodegradability of sewage, in water during SS height, and hydrolysis Bacterium is caught by ectoplasm, is hydrolyzed into molecule part with exoenzyme and enters back into intracellular metabolism, and incomplete metabolism can make SS becomes dissolved organic matter；In Aeration tank 6, promote mixing by discharging the water displacement of bubble, and water and bubble it Between contact cause oxygen to transmit, and be released along pipeline, system have a certain amount of free-pouring, with maximally effective, have Chemically inert medium, as medium, has been broken the socket of the antibacterial of undressed sewage, has been supplied oxygen by roots blower Gas further speeds up to sewage and media and punctures, and is simultaneously fed into the microorganism embedded in the media, and this will cause microorganism to replicate, Thus each second discharges billions of microorganisms, thus microorganism amount reproduction is the most, in this process, in liquid Biochemical oxygen demand BOD and ammonia nitrogen be decreased sufficiently；In flocculation basin 8, according in sewage flocculate source determine addition PAC or PAM, stirs and uses Double-curved-surface stirring machine, sedimentation tank middle hopper shape, and drying bed squeezed into by bottom sediment pump, and supernatant enters heavy Pond, shallow lake, water outlet enters sterilization pool 10, qualified discharge after ozonator is sterilized；The mud produced in native system is mainly thing Changing mud and biochemical excess sludge, can meet significantly by the excess sludge in system being delivered to natural filtration on drying bed Reduce mud moisture content, containing the effect by filtering layer of the mud waste water, retain mud, filtrate is oozed out by bottom, enter original place reason System processes again, and weather conditions cannot be carried out taking folded spiral shell dewaterer desliming during dewatered sludge, is just reaching sewage disposal system Often operating.2 sewage pumps, the using and the reserved are installed in sump；Preliminary sedimentation tank is provided with 1 sludge pump, is contained in pond, regulation Pond and hydrolytic tank are anti-base sludge precipitation, install boring aeration pipe；Second pond is provided with 2 sludge reflux pumps, is contained in pond, The using and the reserved；Flocculation basin and sedimentation tank are mounted on 1 curved surface blender, chemicals dosing plant, PH meter etc., and are respectively mounted 2 mud Pump is in pond；1 sludge pump is installed at the bottom of the pond of sludge-tank.Being additionally provided with multiple valve on sludge stream is threaded a pipe, UASB reacts Being additionally provided with pipeline pump between the pipeline that device pond condensing with mud connects, effect is that the mud in UASB reactor is taken away.
