In in bottom deposit, it is unfavorable for the organic component that muddy water is sufficiently mixed in contact degrading waste water, anaerobic sludge is easy to run off simultaneously,
Need to arrange sedimentation tank 7A, nor make full use of the pH that the basicity after anaerobic treatment adjusts original waste water, reduce the consumption of alkali
Amount.
Content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus providing a kind of multistage change flow velocity anaerobic reaction
Device, is applied to the bad organic wastewater anaerobic treatment of biochemical, by multistage change flow velocity design, can ensure that inside reactor muddy water
Mixture is sufficiently mixed, and improves anaerobic biological removal efficiency to greatest extent, reduces the loss of anaerobic sludge.
The technical scheme providing according to this utility model, multistage change flow velocity anaerobic reactor includes retort, in retort
It is sequentially provided with tank, three phase separator, upflow anaerobic sludge blanket reactor and water-distributing device from top to bottom, it is characterized in that：Cloth
The water inlet end of water installations connects the water side of water pump by water inlet pipe, and the water side of tank connects subsequently aerobic system by drain pipe
System；The water inlet end that two grades of return ducts connect water pump is passed through in the water side of upflow anaerobic sludge blanket reactor, and upflow type anaerobic is dirty
Connect the water inlet end of water pump by one-level return duct before the water inlet end of mud bed reactor.
Further, two grades of return ducts are provided with secondary valve door, secondary valve door can control two grades of return ducts unlatching and
Close.
Further, one-level return duct is provided with one-level valve, one-level valve can control one-level return duct unlatching and
Close.
Compared with the prior art this utility model has advantages below：
This utility model structure is simple, compact, reasonable, can guarantee that muddy water conversion zone upflow velocity flexibly controls, muddy water
Mixing is full and uniform, and mud does not produce deposition, improves reaction effect；Can guarantee that mud-water separation area upflow velocity is extremely low, maximum
Limit retains anaerobic sludge；Need not supporting sedimentation tank, floor space is little, and cost of investment is low；Anaerobic treatment water outlet can be made full use of
Basicity, reduces original waste water and adjusts the consumption to alkali for the pH, operating cost reduces.

Specific embodiment
The embodiment combining in accompanying drawing is further described by this utility model below：
As shown in Fig. 2 this utility model mainly includes retort 3, in retort 3, it is sequentially provided with tank 6, three from top to bottom
Phase separator 5, upflow anaerobic sludge blanket reactor 4 and water-distributing device 2.
The water inlet end of water-distributing device 2 connects the water side of water pump 1 by water inlet pipe, and drain pipe is passed through in the water side of tank 6
Connect follow-up aerobic system.
The water inlet end that two grades of return ducts 8 connect water pumps 1 is passed through in the water side of upflow anaerobic sludge blanket reactor 4, two grades
Return duct 8 is provided with secondary valve door 10, and secondary valve door 10 can control the opening and closing of two grades of return ducts 8.Increase by two grades to return
Flow tube enables region upflow velocity 1.0 ~ 2m/h between one-level return duct and two grades of return ducts, and mud mixture is complete in this region
Full suspended state, improves muddy water contact area and time further, improves removal effect.Control up flow type by increasing return duct
Anaerobic mud bed reactor bottom flow velocity, the upflow velocity enabling region on two grades of return ducts is held at less than 0.5m/h,
Enable three phase separation effect to greatest extent, retain anaerobic sludge, sedimentation tank need not be set.
By the water inlet end of one-level return duct 7 connection water pump 1 before the water inlet end of upflow anaerobic sludge blanket reactor 4, one
Level return duct 7 is provided with one-level valve 9, and one-level valve 9 can control the opening and closing of one-level return duct 7.Increase one-level to return
Flow tube enables the highly following upflow velocity 5 ~ 8m/h of one-level return duct it is ensured that in the little situation of the bad gas production of biochemical
Under, mud mixture is fully thoroughly mixed state in this region, is unlikely to sludgd deposition phenomenon, reduces removal effect.
Operation principle of the present utility model is：During work, original waste water is first and many before squeezing into retort by intake pump
After level becomes flow velocity anaerobic reactor water side and the recirculation water mixing of water inlet end, by water-distributing device water distribution uniformity, up flow type is detested
The water of oxygen sludge bed reactor water side and water inlet end passes through two grades of return ducts and the backflow of one-level return duct, secondary valve door and one-level
The opening and closing of Valve controlling return duct, control the flow velocity of the internal zones of different of upflow anaerobic sludge blanket reactor to become
Change, the highly following upflow velocity of one-level return duct controls in 5 ~ 8m/h, between one-level return duct and two grades of return ducts, region rises
In 1.0 ~ 2.0m/h, two grades of upflow velocities of region between return duct and rhone control less than 0.5m/h flow speed control, degrade
Waste water afterwards is realized gas-liquid-solid three-phase in three phase separator and is separated, and discharges upflow anaerobic sludge subsequently into rhone after collecting
Bed reactor, enters follow-up aerobic system.
