Description
Technical field
This utility model relates to a kind of MBR sedimentation tank, belongs to technical field of sewage.
Background technology
MBR membrane bioreactor is activated sludge process and membrane separation technique to be combined, and replaces the sewage disposal new method of second pond in tradition conventional activated sludge method with membrane separation technique.Compared with traditional activated sludge process, it is good and stable that it has effluent quality, and excess sludge production is few, and floor space is little, be easily installed, and runs many advantages such as easy to operate.Meanwhile, in actual application, there is also some problems, such as easy pollution, energy consumption is high, and the life-span is relatively short.
The method controlling fouling membrane has a lot, and wherein, a kind of topmost method is to utilize continuous aeration that film surface is washed away.In order to reach to control the effect of fouling membrane, the air capacity required for aeration and the ratio processing the water yield are at least 20:1, thus causing that operation energy consumption is greatly increased.By the operation energy consumption of actual MBR engineering is analyzed discovery, aeration energy consumption at least accounts for about the 80% of total energy consumption.Additionally, aeration intensity is excessive, there is also the problems such as film silk fracture, thus have impact on the service life of MBR film.Therefore, under the premise effectively controlling fouling membrane, the focus that aeration rate is research how is reduced.
Summary of the invention
The purpose of this utility model is in that to overcome above-mentioned deficiency, it is provided that a kind of MBR sedimentation tank, and its simple in construction is easy to operate, can reduce aeration energy consumption while not affecting film service life.
The purpose of this utility model is achieved in that a kind of MBR sedimentation tank, it includes sedimentation tank body, this internal left side of described sedimentation tank is provided with former and later two MBR membrane modules being arranged in parallel, this internal right side of described sedimentation tank is provided with aerator, described aerator includes air inlet pipe and rectangular tube group, described air inlet pipe is connected with rectangular tube group, and described rectangular tube group is provided with multiple corundum-aerator, and the plurality of corundum-aerator is that matrix-style is arranged.
Described MBR membrane module includes fixed frame, described fixed frame is arranged with in parallel multiple hollow curtain type membrane, on front side of the plurality of hollow curtain type membrane, bottom is provided with the first aeration tube, the plurality of hollow curtain type membrane center top is provided with the second aeration tube, and the plurality of hollow curtain type membrane backside top is provided with outlet pipe.
Described sedimentation tank body right upper portion is provided with water inlet pipe.
On front side of described sedimentation tank body, bottom is provided with evacuated tube.
Described sedimentation tank inner body wall is provided with epoxide coal bituminous layer.
Compared with prior art, this utility model has the advantages that
This utility model one MBR sedimentation tank, its simple in construction, easy to operate, aeration energy consumption can be reduced while not affecting film service life.
