Abstract
The utility model discloses an energy-saving sludge backflow device of a membrane bioreactor. The energy-saving sludge backflow device is characterized in that sludge in a membrane reaction region flows backwards to a facultative anaerobic region through a gas stripping device, so that a reflux pump device is omitted, and the purpose of saving energy sources is achieved.
Description
Technical field
The utility model discloses a kind of membrane bioreactor mud reflux, belong to the waste disposal plant field, particularly relate to a kind of energy-conservation membrane bioreactor mud reflux.
Background technology
In sewage treatment process, utilize aerobe method to handle pollutent, aerobic processes can produce excess sludge, and this part mud major part also has active, so the sludge quantity in the assurance aerobic processes that need reflux.Traditional sludge refluxes and to be back to aerobic area by power-equipments such as reflux pumps, and consequent electric energy and front-end investment be all than higher, and to reflux be step, and this certainly will cause idleness of equipment waste.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of energy-conservation membrane bioreactor mud reflux.
The technical scheme that the utility model adopts is: pipeline is extended mud bottom, film reaction district, other one is connected to the aerobic area that needs backflow, in pipeline middle part perforate, the pipeline that connects blower fan is put into the pipeline that extends the mud bottom, by the air lift principle, with the intermittent backflow of mud.
Compared with prior art, the beneficial effects of the utility model are: the utilization of innovation the air lift principle, the unnecessary air quantity that utilizes blower fan in the aerobic processes to produce reaches mud air lift effect by sludge return pipe.Need not to increase any power set, mud can be refluxed, this has saved front-end investment and working cost greatly.
Description of drawings
Fig. 1 is a kind of energy-conservation membrane bioreactor mud reflux;
Embodiment
8 one in returned sluge pipeline is extended 2 bottoms, film reaction district, and an other aerobic area 1. that is connected to the need backflow is put into returned sluge pipeline 8 tappings in the 8 middle part perforates of returned sluge pipeline with breather line 7, extends 1/3 place, returned sluge pipeline bottom internally.Start blower fan 5, just can pass through the air lift principle, control mud is intermittent to reflux; Switch by valve 6 control breather lines 7.
Below in conjunction with accompanying drawing the utility model is further specified.
As shown in Figure 1,
Sewage enters in the aerobic area 1, and oxygen compatibility pool 1 mainly carries out the denitrification denitrogenation reaction, and sewage enters into film reaction district 2 afterwards, and the membrane cisterna bottom is provided with microporous aeration device, carries out aeration, realizes nitration reaction, removes the ammonia nitrogen in the sewage, and decomposing organic pollutant; For satisfying the denitrification functions in film reaction district 2, be provided with returned sluge pipeline 8.By in blower fan 5, inserting breather line 7, control the switch of breather lines 7 in the middle of the breather line 7 by valve 6; Before the blower fan in starting outfit district 3, open valve 6, gas enters in the mud return line 8 by breather line 7, treat certain hour after, mud return line will suck film reaction district 2 bottom mud automatically, enter in the aerobic area 1.Film reaction district 2 water enter clear water zone 4 by film reaction system 9.
Claims (2)
1. an energy-conservation membrane bioreactor mud reflux is characterized in that: by air-lift device film reaction district mud is back to aerobic area, thereby reduces the reflux pump equipment configuration, reach energy-conservation purpose.
2. a kind of energy-conservation membrane bioreactor mud reflux according to claim 1 is characterized in that: utilize the wind surplus of the blower fan generation in the aerobic processes to reach the effect of air lift, and needn't increase blower fan newly.
