The vertical MBR membrane biological treatment tank provided by the invention utilizes vertically arranged tank body to let sewage form a downward pressure because of the action of gravity, and increases the ultrafiltration membrane driving pressure, thereby reducing energy consumption, and saving later use and maintenance cost.
Description
Technical field
The invention belongs to sewage-treatment plant, be specifically related to a kind of vertical MBR film biological treatment tank.
Background technology
Solid-liquid separating type membrane bioreactor is the class membrane bioreactor studying the most extensively and profoundly in water treatment field, is that a kind of membrane separating process replaces the water technology of secondary sedimentation tank in traditional activated sludge process；Membrane separation technique is organically combined by MBR with traditional biological treatment technology, MBR realizes the separation of sludge retention time and hydraulic detention time, substantially increase solid-liquid separation efficiency, and due to the increase of activated sludge concentration and the appearance of specially good effect bacterium (particularly dominant microflora) in mud in Aeration tank, improve biochemical reaction rate；Meanwhile, reduce excess sludge generation amount by reducing F/M ratio, thus substantially solve many outstanding problems that traditional activated sludge process exists.
Although MBR can solve the problem that a lot of problems that traditional activated sludge process is brought, but the separation process of the MBR membrane bioreactor in prior art must keep certain film to drive pressure, next to that MLSS concentration is the highest in MBR pond, keep enough oxygen transfer rates, aeration intensity must be strengthened, also have to strengthen membrane flux, alleviating fouling membrane, it is necessary to increase flow velocity, washing away film surface, the energy consumption causing MBR is higher than traditional biological treatment.
Summary of the invention
In order to solve the problem of above-mentioned prior art, the present invention provides a kind of vertical MBR film biological treatment tank that can utilize water body self gravitation strengthening membrane driving force.
The present invention is achieved through the following technical solutions:
A kind of vertical MBR film biological treatment tank, including vertical tank body, described vertical tank wall top is provided with water inlet pipe, and bottom is provided with conical flow guiding pipe, and conical flow guiding pipe bottom connects has MBR hyperfiltration membrane assembly, MBR hyperfiltration membrane assembly to be provided with outlet pipe；Vertical tank body can utilize certain discrepancy in elevation to make the water body pressure downward because action of gravity has, and the conical flow guiding pipe being provided with at vertical tank body lower part can reduce the contact area of MBR hyperfiltration membrane assembly and water body, thus increase the pressure of ultrafiltration membrane surface further, increase film and drive pressure, decrease energy consumption.
Further, it is provided with floating filler in described vertical tank body；Floating filler has bigger specific surface area, and biofilm effect is preferable, it is easy to overhauls and changes, it is simple to the operation and maintenance in later stage.
Further, described floating filler is two-layer equation spherical structure, and outer layer is latticed polyethylene spheres, and inner core is thread filler.
Further, described vertical tank base corner location is equipped with leg.
Further, described vertical tank body inner bottom part is provided with aeration tube.
Further, described aeration tube is provided with aeration opening.
Further, described vertical tank wall is provided with aerator, and aerator connects with aeration tube；Forcing ambient air can be pressed in aeration tube by aerator and then carry out aeration operation by aeration opening.
Further, described vertical tank body top has opening, and opening goes out to be provided with exhaust fan.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) this apparatus structure is compact, and floor space is less.
(2) this device utilizes vertical tank structure, it is possible to utilizes water body self gravitation effect to strengthen the skin covering of the surface driving force of MBR hyperfiltration membrane assembly, reduces energy consumption.
