Fang Jianli sewage treatment plants and regeneration water factory, seawater desalting plant etc., alleviate demand of the economic development to water resource to a certain degree.
Membrane bioreactor is that membrane separation technique is combined new water technology with biotechnology, and art is handled relative to traditional wastewater,
MBR has that effluent quality is good, floor space is small, sludge retention time and hydraulic detention time are sufficiently separated, it is swollen not to be afraid of sludge
The advantages of swollen, control easy to automate, but MBR membrane module is easy to pollute and blocked, causes system operation unstable
Calmly, the shortcomings of cleaning frequency is short, cleaning agent easily causes secondary pollution.It is well known that especially sludge is dense in MBR membrane cisternas
When spending higher situation, pollution and blocking are more serious, the increase pair while the normal operation in order to ensure MBR systems is had to
The intensity that the air-blowing of film surface is swept, causes energy consumption further to increase.Therefore, the mixed liquor sludge of reduction MBR film process units is dense
Degree, can effectively slow down the pollution and blocking of MBR films.While in order to keep the higher microorganism of biological respinse pool unit dense
Degree, makes MBR systems have the advantages that high capacity of resisting impact load, it is necessary to set device for separating mud and water before membrane cisterna, will divide
The activity sludge reflux separated out is in biological reaction pool.But, most of device of existing reduction sludge concentration is to need
One single device for separating mud and water is set between biological respinse unit and submerged membrane processing unit, in existing MBR systems
Or biological reaction pool structures are reconstructed extremely inconvenient, especially structures are compact, not enough sewage treatment plant standby.
Meanwhile, the space occupied by device for separating mud and water only just corresponds to rapid sedimentation tank, is utilized without sufficiently effective.
Utility model content
Problem to be solved in the utility model is to provide a kind of offer compact conformation, occupies little space, can be lowered into

Swash plate group is provided with above plate, dividing plate is provided between sedimentation basin and membrane biological reaction pond, the dividing plate upper end is provided with guiding gutter, described
It is provided with regulating reservoir in the first aeration tube, the membrane biological reaction pond and is provided with the second aeration tube, first aeration tube and second
Membrane module is set in aeration tube connecting fan, membrane biological reaction pond, and the membrane module connects water producing pipe, the water producing pipe connection circle
Piston is set in the bottom surface of the piston cylinder of tubular, the piston cylinder, and the piston connects piston rod, and piston rod stretches out piston cylinder
Upper bottom surface, is provided with sealing device, the other end connection drive device of the piston rod, institute between piston rod and piston cylinder upper bottom surface
State one end away from water producing pipe on the side wall of piston cylinder and outlet pipe is set, the upper bottom surface of the piston cylinder sets pressure-reducing valve, described
The junction of outlet pipe and piston cylinder sets check-valves.
The membrane biological reaction bottom of pond portion is provided with the second immersible pump, and second immersible pump described in aqueduct UNICOM by lacking
Oxygen pond.
The angle of the swash plate group and horizontal direction is 35 degree.
Membrane bio-reaction system of the present utility model, it is simple in construction, it is cheap, work well.Because anoxic pond is with sinking
Swash plate group is provided between the pond of shallow lake, when sewage flows through swash plate group, swash plate group helps to form good hydraulic flow state, and shale etc. is consolidated
The speed of body impurities sink down is significantly increased, and then reduces the sludge concentration for entering submerged membrane processing unit, extension membrane module
Use time.Due to being provided with piston cylinder and piston, when that need not rinse, piston cylinder without prejudice to works, and is pushed away when needing and rinsing
Piston enters membrane module by water back-pressure is produced, and produces larger reverse flow, membrane module is backwashed.
