Description
Technical field
The invention belongs to biologic packing material aeration tank technical fields, are related to a kind of fixed HMBR technique aeration of biologic packing material
Pond.
Background technique
Biologic packing material is installed in the aeration tank of common membrane bioreactor (CMBR), is run after a certain period of time, on filler
Certain thickness biomembrane can be grown, the membrane bioreactor of this form is referred to as combined film bioreactor (HMBR).
Compared with CMBR, not only there is suspended biomass (activated sludge) in the aeration tank of HMBR, also while there is the micro- life of adhesion
Object (biomembrane).Test result shows compared with CMBR, and since biomass significantly improves, HMBR has preferably biodegrade
Ability.In addition, HMBR also has good control membrane fouling ability compared with CMBR, the cycle of operation of membrane module is greatly prolonged.
The biologic packing material used is Mobile biological filler, and filler is in fluidized state in aeration tank, and the denitrogenation dephosphorizing ability of HMBR is simultaneously
It is undesirable.
Summary of the invention
The purpose of the present invention is to provide a kind of biologic packing material fixed HMBR technique aeration tank, beneficial effects of the present invention
It is the denitrogenation dephosphorizing ability height of aeration tank, dredging effect is good.
The technical scheme adopted by the invention is that include aeration tank, if the aeration tank in be equipped with dry plug training wall, training wall and
Membrane module, the self priming pump outside membrane module connection are equipped between pool wall, membrane module lower section is equipped with aeration head, and aeration bottom of pond portion is equipped with
Sludge pipe, fixed type biological filler is installed in aeration tank, and raw water is pumped into aeration tank by grid by raw water.
Further, there are two the effects of aeration: one is to provide the dissolved oxygen that Institute of Micro-biology needs；Second is that rising bubble can rush
Brush film wire surface, effectively control fouling membrane, in addition, bubble can generate gas stripping when rising, when mixed liquor flows through biologic packing material,
Since biologic packing material is fixedly mounted, the hole between filler is smaller, is easy retention, gathers a large amount of microorganism, the resistance to mass tranfer of oxygen
Larger, the dissolved oxygen concentration in the effect of oxygen transfer resistance, mixed liquor can gradually decrease, final that anoxic even anaerobism shape is presented
State can be alternately present aerobic zone, anoxic zone and anaerobic zone along water flow flow direction, and aerobic zone is located at aeration tank locating for membrane module
Region, by the Dissolved Oxygen concentration Control of the area top mixed liquor in 1mg/L when operation, anoxic zone is located at biologic packing material fixed bed
Top, anaerobic zone is located at the lower part of biologic packing material fixed bed, due to being alternately present for aerobic zone, anoxic zone and anaerobic zone, instead
It answers device that can carry out the nitration reaction under aerobic condition and inhales phosphorus reaction and anti-nitration reaction and anaerobic condition under anoxia condition
Under release phosphorus reaction.
Detailed description of the invention
Fig. 1 is aeration tank system structure diagram.
In figure, 1. aeration tanks, 2. training walls, 3. membrane modules, 4. self priming pumps, 5. aeration heads, 6. sludge pipes, 7. biologies are filled out
Material, 8. grids, 9. raw water pumps.
Specific embodiment
The present invention is described in detail With reference to embodiment.
Aeration tank of the present invention is as shown in Figure 1, include aeration tank 1, if being equipped with dry plug training wall 2, training wall 2 in aeration tank 1
Membrane module 3 is equipped between pool wall, membrane module 3 connects external self priming pump 4, is equipped with aeration head 5, aeration tank 1 below membrane module 3
Bottom is equipped with sludge pipe 6, and fixed type biological filler 7 is installed in aeration tank 1, and raw water is pumped into aeration tank by raw water pump 9 by grid 8
In 1.
Training wall 2 is installed in the aeration tank of HMBR 1, biologic packing material 7 is fixedly mounted between training wall 2 and pool wall.
Membrane module 3 is mounted on the side of aeration tank 1 at pool wall, and aeration head 5 is arranged in lower section.There are two the effects of aeration: first is that mentioning
The dissolved oxygen needed for Institute of Micro-biology；Second is that film wire surface can be washed away by rising bubble, fouling membrane is effectively controlled.In addition, on bubble
Gas stripping can be generated when rising, flows the arrow direction along figure of the mixed liquor in aeration tank 1.Mixed liquor flows through biologic packing material 7
When, since biologic packing material 7 is fixedly mounted, the hole between filler is smaller, is easy retention, gathers a large amount of microorganism (activated sludge
And biomembrane), the resistance to mass tranfer of oxygen is larger.Dissolved oxygen concentration in the effect of oxygen transfer resistance, mixed liquor can gradually decrease,
It is final that anoxic even anaerobic state is presented.Therefore, aerobic zone, anoxic zone and anaerobic zone can be alternately present along water flow flow direction.
Aerobic zone is predominantly located in figure 1 right area of aeration tank locating for membrane module 3, and when operation can be by the molten of the area top mixed liquor
Oxygen concentration control is solved in 1mg/L or so.Anoxic zone is predominantly located at the top of 7 fixed bed of biologic packing material, and anaerobic zone is predominantly located at life
The lower part of 7 fixed bed of object filler.Due to being alternately present for aerobic zone, anoxic zone and anaerobic zone, reactor can carry out aerobic condition
Under nitration reaction and inhale and release phosphorus reaction under phosphorus reaction and anti-nitration reaction and anaerobic condition under anoxia condition.Therefore,
Compared with the HMBR of installation fluidisation state biologic packing material, the HMBR of installation fixed type biological filler has better denitrogenation dephosphorizing energy
Power.
The above is only not to make limit in any form to the present invention to better embodiment of the invention
System, any simple modification that embodiment of above is made according to the technical essence of the invention, equivalent variations and modification,
Belong in the range of technical solution of the present invention.
