Description
Technical field
Flap anaerobic reactor (ABR) system for multiple spot backflow, belongs to sewage treatment technology.
Background technology
Along with environmental pollution gradually pay close attention to by people, increasing water pollutions technology is developed.The seventies in last century, from the external upward flow sludge reaction bed (English abbreviation UASB) introduced, once by spread.But find in practice, this equipment has a problem not to be solved all the time.Be exactly that sectional area is large, current lift velocity is slow, and the residence time is long, and water distribution is uneven, and water easily walks short circuit in a reservoir, and the water of partial volume is immobilising, can not play a role, and cause reaction not exclusively, processing efficiency is low.If the process water yield is large, the residence time is long, then device height can be caused too high, and complex structure, cost is high.
Folded plate type anaerobic reactor (English abbreviation ABR) is a kind of follow-on UASB technology, ABR technique is provided with upper and lower traverse baffle in the reactor and forms the compartment of connecting successively in water (flow) direction, thus make the different compartments along its length of microbial population wherein realize producing being separated of acid and methanogenic phase, in single reactor, carry out two-phase or multiphase operation.That is, ABR technique can realize two-phase or multiphase treating processes of integration in a reactor.
On structure construction, ABR is more simpler than UASB, the triphase separator that Structure of need is comparatively not complicated, the aerogenesis of each compartment can collect separately to analyze the degradation effect of each compartment, microorganism to organic decomposition approach, mechanism and microorganism type wherein, also can by the aerogenesis in reactor together centralized collection.
Current are along in flap reactor (ABR), constantly seethe up and down, reactor becomes multistage and to turn back form, highly corresponding step-down, extend reaction scheme, increase the reaction times, like this, under the condition of constancy of volume, the sectional area of reactor can be relatively smaller, after flow velocity improves, optimize uniformity of water distribution, anaerobic reaction is effective.But these change the requirement that still can not meet waste water treatment, the micro-polluted water that concentration is more and more higher is also more and more higher to the efficiency requirements of wastewater treatment.And still can stay dead angle in the upper and lower three dimensional angle of this flap, also there is the phenomenon that reaction is incomplete, adjustment means are few, directly have influence on anaerobic reaction efficiency and result.
Utility model content:
In order to solve common flap anaerobic reactor (ABR), water distribution is not too even, and backflow has dead angle, the problem that flow cannot adjust, flap anaerobic reactor (ABR) system that the utility model provides a kind of multiple spot to reflux, the feature of this system is by each lattice sewage (mud) of water pump forced refluence ABR, adds discharge in space, improves hydraulics, optimize inside reactor uniformity of water distribution, flexibly, arbitrary combination, improves the reaction efficiency of ABR in adjustment.
The technical solution of the utility model is as follows:
A kind of flap anaerobic reactor system of multiple spot backflow, comprise the first reaction chamber I, the second reaction chamber II, the 3rd reaction chamber III and settling tank IV that are connected successively by reaction chamber wall, it is characterized in that, with the bottom of settling tank bottom each reaction chamber of common flap anaerobic reactor, be separately installed with branch drain, converge main 5 by a underflow each branch drain is linked into an integrated entity, each branch drain is installed underflow control valve 4, converge on main 5 at underflow and backflow recycle pump 3 is installed; On the pipeline of the rising pipe 6 of reflux cycle pump 3, be divided into some exit branch, be positioned at the top of the first reaction chamber and the second reaction chamber; Exit branch is equipped with recycle pump exit branch control valve.
The flap anaerobic reactor system of above-mentioned multiple spot backflow, also comprises: the rising pipe 9 of connection first reaction chamber and the second reaction chamber is equipped with on the top between the first reaction chamber and the second reaction chamber; The rising pipe 10 of connection second reaction chamber and the 3rd reaction chamber is equipped with on top between the second reaction chamber and the 3rd reaction chamber; The rising pipe 11 of connection the 3rd reaction chamber and settling tank is housed on the 3rd top between reaction chamber and settling tank; On the top of settling tank, clear liquid rising pipe 7 is housed.
Above-mentioned valve random combine, can pump to the sewage (mud) in any reaction chamber in other reaction chamber arbitrarily.Backflow sewage (mud) adds discharge in reaction chamber, improves hydraulics, optimizes the inner uniformity of water distribution of reaction chamber, and flexibly, arbitrary combination, improves the reaction efficiency of ABR in adjustment.
The gas separated in sewage, as H
2, CO
2, CH
4, H
2s etc., effuser maintains the form of existing regulation and stipulation.
The flap anaerobic reactor system of described multiple spot backflow, due to after ABR reactor, devises settling tank, using the underflow of settling tank as reflux medium, can participate in reactor.In addition, adjusted by valve, the water level height in each space can be regulated.
Sewage enters the first reaction chamber of ABR system, enters the second reaction chamber in turn, and the 3rd reaction chamber, finally enters settling tank, carries out solid-liquid separation, and supernatant liquor is discharged from settling tank top.In order to strengthen this system response effect, open backflow water pump, according to the Inlet and outlet water parameter of each reaction chamber, microbial, microorganism concn comparative analysis, determine the sewage source of backflow water pump, backflow sewage whereabouts and the backflow water yield, continuous adjustment backflow source, quantity of reflux, return time, backflow whereabouts, reach overall ABR system response effect optimum.
Can also according to water change of water quality, adjustment backflow source, quantity of reflux, backflow whereabouts, time of flow targetedly, the efficiency change of continuous adaptive response device.
Advantage of the present utility model: add discharge in space by backflow sewage (mud), improve hydraulics, optimize inside reactor uniformity of water distribution, adjustment flexibly, arbitrary combination, changes microorganism concn, increases underflow and admittedly contains, performance reactor function that can be maximum, improves the reaction efficiency of ABR.
System internal reflux water pump PLC controls, and valve adopts motorized valve, can realize reflux operation full automatic control.
