Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model, the technical scheme in this utility model is clearly and completely described, Obviously, described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on this reality By the embodiment in novel, the every other reality that those of ordinary skill in the art are obtained under not making creative work premise Execute example, broadly fall into the scope of this utility model protection.

As it is shown in figure 1, a kind of UASB reactor proposed for this utility model embodiment, including reactor body 1, reaction Device body 1 top is provided with biogas gas gathering manifold 2, offers many to reactor body 1 internal vertical on biogas gas gathering manifold 2 Individual biogas gas-collecting branch pipe 21, three phase separator 3, the relative biogas collection of biogas gas gathering manifold 2 are installed in the bottom of biogas gas-collecting branch pipe 21 Tank for sewage gas 4 is inserted in one end of gas branch pipe 21, and the top of tank for sewage gas 4 and bottom side further respectively have the first water inlet pipe 41 and row Water pipe 42；Being provided with thermometer 5 on the sidewall of reactor body 1, one end insertion reaction device body 1 of thermometer 5 is internal, The other end exposes reactor body 1, and side, reactor body 1 top is provided with overfall 6, and the lower section of overfall 6 is provided with clear liquid Pipe 7, reactor body 1 is provided with the second water inlet pipe 8 near bottom side, is provided with and takes between clear liquid pipe 7 and the second water inlet pipe 8 Sample pipe 9, reactor body 1 is provided with blow-down pipe 10 and manhole 11 relative to the side of the second water inlet pipe 8, and manhole 11 is arranged on Between blow-down pipe 10 and thermometer 5.

Having water-locator 12 as in figure 2 it is shown, connect on the second water inlet pipe 8, water-locator 12 is by multiple water distribution branch pipes 121 and electronic Machine 122 forms, and each water distribution branch pipe 121 connects a motor 122, and water distribution branch pipe 121 is connected with the second water inlet pipe 8.

The processing procedure of present device is to enter preliminary sedimentation tank after, percolate removes the float such as abandoned tender paper through grid, heavy Fine suspension waste water in the waste water of shallow lake, after preliminary sedimentation tank carries out mud-water separation, flows into regulating reservoir certainly, enters the water quality and quantity of waste water Row regulation, and heat when water temperature is relatively low, after waste water is adjusted pond regulation, elevator pump it is promoted to anaerobic UASB reaction Device.Process degradable most COD and BOD through anaerobic UASB reactor of the present invention.

Below in conjunction with the accompanying drawings the operation principle of the present invention is described as follows:

UASB is upflow anaerobic sludge blanket reactor, and whole reactor body can be divided into three regions: sludge reaction district, Gas-liquid-solid three-phase separator (including settling zone) and air chamber.Sewage is by the bottom of water pump lifting to anaerobic reactor, bottom utilization Water distribution system sewage is uniformly distributed on whole cross section；Utilize outlet pressure and the gas-forming reaction of water inlet, make waste water with high The anaerobic sludge of concentration is fully contacted and mass transfer, by the organic matter degradation in waste water；Waste water slowly rises in reaction zone, further Degradation of organic substances, in gas, water, mud uphill process at the same time, biogas is initially entered three phase separator inside and is arranged by pipeline Going out, mud and waste water rise to Disengagement zone by the gap of three phase separator, and the mud in sewage flocculates, and granule gradually increases Greatly, and under gravity settle.The mud being precipitated on skew wall slides back to, in anaerobic reaction district, make reaction zone inner product along skew wall Tired substantial amounts of mud, the process water outlet after separating with mud is overflowed from downflow weir top, settling zone, is then discharged out Sludge Bed.

The biogas (mainly methane and carbon dioxide) produced under anaerobic state causes the circulation of inside, and this is for granule sludge Formation and maintain favourable.Sludge blanket formed some gases be attached on mud granule, adhere to and not have adhere to gas to Reactor head rises.The mud rising to surface clashes into the bottom of phase reactor gas launcher, causes the dirt of bubbles attached Mud flco deaerates.After bubble release, mud granule will be deposited to the surface of Sludge Bed, adhere to and not have the gas of attachment to be collected into The collection chamber of the three phase separator of reactor head.Be placed in the baffle plate under collection chamber unit interstices act as gas launcher and Prevent biogas bubble from entering settling zone, otherwise the wadding causing settling zone is moved, granule can be hindered to precipitate.Comprise some remaining solids With the liquid of mud granule through entrance settling zone, separator gap.

Compared with prior art, this utility model at least has the advantage that

By above-mentioned the technical solution of the utility model, the bottom of USAB reactor is suspended sludge bed, and top is anaerobism filler Filter bed, it is strong that it has anaerobic mud bed and anaerobism filter bed feature, sludge retention ability and capacity of resisting impact load simultaneously, dirty Mud concentration is high, and its COD volumetric loading is up to more than 10kgCOD/ (m3 d).The water inlet of USAB reactor is by water-locator Complete, use multipoint water feeding mode, to guarantee that water distribution is uniform.Can cultivate and form the mud granule that settling property is good, form dirt The Sludge Bed of mud very high concentrations so that it is having volumetric loading high, sludge retention is effective, it is a series of excellent that structure of reactor is compact etc. Good operation characteristic.USAB reactor is not only in that the Organic substance removing diafiltration, but also can be incited somebody to action by hydrolysis acidification effect The Organic substance thing of bio-refractory is converted into easy biochemical degradation Organic substance, improves aftertreatment device to organic removal efficiency.

The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not limited to This, any those familiar with the art in the technical scope that this utility model discloses, the change that can readily occur in or Replace, all should contain within protection domain of the present utility model.Therefore, protection domain of the present utility model should be wanted with right The protection domain seeking book is as the criterion.
