Abstract
The utility model discloses a membrane biological reactor MBR. The membrane biological reactor comprises a reaction tank, wherein the reaction tank is divided into a degradation region and a membrane filtering region through a guide plate; a guide hole is formed at the upper part of the guide plate; a stereoscopic elastic filler is arranged in the degradation region; a suspension filler and a membrane assembly are arranged in the membrane filtering region; and the membrane assembly is connected with a suction pump. The service life of a membrane can be effectively prolonged and larger membrane flux of a system is kept at the same time so as to guarantee the processing effect and efficiency.
Description
Technical field
The utility model belongs to field of Environment Protection, is specifically related to a kind of MBR membrane bioreactor.
Background technology
The MBR membrane bioreactor is the high efficiency technical technique of binding film isolation technique and biological treatment, can effectively carry out mud-water separation, and have the unrivaled advantage of traditional waste water treatment process: can realization response device hydraulic detention time HRT and fully the separating of SRT; Floor space is little; System is nitrated good, and hardly degraded organic substance has obtained further fully degraded; Excess sludge production is extremely low etc.But also there is very large deficiency in traditional reactor: the one, and it is short work-ing life that film pollutes the film that causes; The 2nd, membrane flux is low.These shortcomings have had a strong impact on promoting the use of of MBR membrane bioreactor.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, and a kind of MBR membrane bioreactor is provided.
Technical scheme: in order to achieve the above object, the utility model is specifically finished like this: a kind of MBR membrane bioreactor, comprise a reaction tank, and this reaction tank is divided into degraded district and membrane filtration district by flow deflector, and flow deflector top has pod apertures; Degraded is provided with 3 D elastic filler in the district, is provided with floating stuffing and membrane module in the membrane filtration district, and membrane module links to each other with reaction tank suction pump outward.
Wherein, more abundant for filler is mixed with sewage, described degraded district and bottom, membrane filtration district can be provided with aeration tube, and the outer gas blower of aeration tube and reaction tank links to each other.
Beneficial effect: the utility model is compared with conventional apparatus, has following advantage:
(1) flow deflector is separated into two districts, and the microorganism in the degraded district is with the aerobic decomposition of pollutent, and what the membrane filtration district processed is to process through the degraded district, the sewage of flow deflector predefecation, and SS concentration reduces;
(2) filler has been installed with the membrane filtration district by the degraded district, for microorganism provides carrier, has improved volumetric loading and impact resistance;
(3) minimizing of film pollution makes system keep larger membrane flux, guarantees treatment effect and efficient;
(4) reduce film and cleaned energy consumption, improved the work-ing life of film.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
As shown in drawings, the disclosed MBR membrane bioreactor of the utility model comprises a reaction tank 1, and this reaction tank 1 is divided into degraded district 3 and membrane filtration district 4 by flow deflector 2, and described flow deflector 2 tops have pod apertures; Be provided with 3 D elastic filler 5 in the degraded district 3, be provided with floating stuffing 6 and membrane module 7 in the membrane filtration district 4, and membrane module 7 link to each other with suction pump 8; Degraded district 3 and 4 bottoms, membrane filtration district are equipped with aeration tube 9, and aeration tube 9 links to each other with gas blower 10.
During the utility model specific works, sewage enters reaction tank 1 by degraded district 3, with after 3 D elastic filler 5 fully contacts, enter membrane filtration district 4 by the pod apertures on the flow deflector 2, contact with floating stuffing 6 in membrane filtration district 4, and under suction pump 8 effects, treated sewage is extracted out by membrane module 7, discharges reaction tank 1.
