Description
Technical field
The invention belongs to waste water treatment process, and in particular to a kind of novel upflow anaerobic sludge blanket reactor.
Background technique
Up-flow anaerobic sludge blanket（Upflow Anaerobic Sludge Blanket, abbreviation UASB）Reactor is lotus
Blue Wageningen agriculture university Leuinga et al. is succeeded in developing between 1973-1977.China started upstream in 1981
The research work of formula anaerobic mud bed reactor.UASB technique has obtained the application of large-scale popularization in China at present, especially
It is even more to have obtained sufficient application in terms of high concentrated organic wastewater processing.From the point of view of current engineering practice, UASB technique by
It is in granular form state in its anaerobic sludge, it is allow to maintain higher sludge concentration in reactor compared to conventional anaerobic technique,
Therefore handling it, organic volumetric loading is higher, and impact resistance ability is stronger.
Although the practice effect of current UASB technique is fine, but improved place in need.UASB Waste at present
The mixing and stirring of water and anaerobic grain sludge are realized by the Gas Stirring of hydraulic mixing and the anaerobism generation of water inlet.
Mainly stirred by the gas that anaerobism generates, but the gas that anaerobism generates must be limited, especially when organic volume is negative
When lotus is low, the gas of generation is less, and the stirring action generated is also just weaker.Can waste water be sufficiently mixed directly with anaerobic sludge
Influence the treatment effect of UASB technique.Now in order to strengthen being sufficiently mixed for waste water and anaerobic sludge, the method for use is to increase
Add interior reflux, such as EGSB technique, is exactly to flow back by the way that increase is interior, i.e., it is useless to strengthen by strong water inlet hydraulic mixing
Water and anaerobic sludge are sufficiently mixed.But energy consumption is high for hydraulic mixing, and mixed effect is also not highly desirable.
Summary of the invention
The object of the invention is to provide a kind of novel upflow anaerobic sludge to solve the defect of above-mentioned UASB technique
Bed reactor.
The technical scheme is that：A kind of novel upflow anaerobic sludge blanket reactor, including reactor body, water inlet
Device, mud discharging device, effluent collection device, distribution device, three phase separator, reaction zone, settling zone, it is characterized in that three phase separation
The gas of device separation discharge enters moisture trap by pipeline and carries out gas-water separation, enters filter later and filters out in gas
Impurity enters distribution device after entering back into booster fan pressurization.Distribution device discharges the gas of pressurization, and the gas of release exists
Stirring action can be played during rising, and coming into full contact with and mixing for waste water and lonely granule sludge is reached with this.
UASB reactor in the process of running, can continue to generate gas.In order to which extra gas to be discharged, it is equipped on exhaust line
Safety valve, when its pressure is more than the setting value of safety valve, safety valve action discharges excessive gas.
Core of the invention thinking is exactly by gases such as the methane, the carbon dioxide that generate UASB reactor, and it is appropriate to do
After pretreatment, into after booster fan adherence pressure, the gas distribution pipe release of UASB reactor is entered back into, the stirring by gas is made
With to realize being sufficiently mixed for waste water and anaerobic grain sludge.Due to being that the gas generated by UASB reactor itself carries out
Stirring, the environment in reactor will not be impacted.After the gas pressurized of UASB reactor, reinjecting reactor can compare
Strong more of the gas agitating effect of existing UASB.Therefore can be provided for reactor higher superficial gas upflow velocity and
Stronger shearing force, and the two conditions attain full and complete satisfaction, and are also easier to, faster realize the granulating of anaerobic sludge.
Waste water enters reaction zone by water feed apparatus, and makes the bottom that reactor body is uniformly distributed in into water.Waste water is reacting
Area and the raw anaerobic reaction of anaerobic grain sludge hybrid concurrency, the gas that anaerobism generates are entered by the exhaust line of three phase separator
Moisture separation removal in gas is entered filter later, filters out the impurity of gas by moisture trap, into booster fan,
After being pressurized by blower, the gas of pressurization enters distribution device and is discharged again.During release, mistake of the gas in rising
Disturbance is formed in journey, to realize that waste water is more fully mixed with anaerobic grain sludge.Gas enters air water point by three phase separator
From device, filter, booster fan, reactor distribution device discharges again, enters back into three phase separator, is thusly-formed closed cycle.
Gas is constantly generated since waste water is reacted with anaerobic grain sludge, pressure increase in pipeline can be made, when line pressure reaches certain
After value, extra gas is discharged by safety valve.After the waste water of reaction zone is cleaned, into settling zone precipitation and separation,
Clear waste water is discharged by effluent collection device.And excess sludge is discharged by mud discharging device.
Novel upflow anaerobic sludge blanket reactor of the present invention, by after the gas boosting that generates anaerobism, then
It is filled with reactor, by the stirring repeatedly of gas, being sufficiently mixed for waste water and anaerobic grain sludge may be implemented, strengthen mass transfer effect
Fruit improves treatment effect.Higher superficial gas upflow velocity and stronger shearing force can be provided for reactor simultaneously, more had
Conducive to the granulating of anaerobic sludge.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, waste water enters reaction zone 12 by water feed apparatus 2, and make to be uniformly distributed in reactor body 1 into water
Bottom.Waste water passes through three-phase separate in reaction zone 12 and the raw anaerobic reaction of anaerobic grain sludge hybrid concurrency, the gas that anaerobism generates
Exhaust line from device 6 enters moisture trap 8, by moisture separation removal in gas, enters filter 9 later, filters out gas
The impurity of body, into booster fan 10, after being pressurized by blower, the gas of pressurization enters distribution device 3 and is discharged again.It is releasing
During putting, gas forms disturbance during rising, to realize that waste water is more fully mixed with anaerobic grain sludge.Gas
Body enters moisture trap 8, filter 9 by three phase separator 6, increases blower 10 and reactor distribution device 3 discharges again, later
Three phase separator 6 is entered back into, closed cycle is thusly-formed.Gas, meeting are constantly generated since waste water is reacted with anaerobic grain sludge
Make pressure increase in pipeline, after line pressure reaches certain value, extra gas is discharged by safety valve 7.By reaction
After the waste water in area is cleaned, into 11 precipitation and separation of settling zone, clear waste water is discharged by effluent collection device 5.It is remaining dirty
Mud is discharged by mud discharging device 4.
