A vibrator is fixed on the upper surface of the membrane module. The controlling system is controllably connected with the vibrator. The membrane bioreactor provided by the invention has a simple structure. According to the invention, the biological reaction tank and a membrane filtering tank are integrated, such that land occupation is reduced. An aeration device is combined with stirring blades, such that oxygen utilization rate and reaction efficiency are improved. The vibrator is combined with the aeration device, such that membrane flux is maintained at a good level, and membrane pollution and blockage are retarded.
Description
Technical field
The present invention relates to a kind of membrane bioreactor, belong to effluent treatment plant.
Background technology
Membrane bioreactor (MBR) is a kind of new type water treatment technology that is combined with biological processing unit by film separation unit, replace second pond with membrane module, in bio-reactor, keep the high reactivity sludge concentration, reducing sewage treatment facility takes up an area, and by keeping low sludge loading reduce mud amount, because fenestra is very tiny, this is so that film has efficient crown_interception, make microorganism be trapped in the bio-reactor fully, compare with traditional biochemical water technology, the MBR processing efficiency is high, effluent quality good and stablize; Facility compact, floor space are little; Easy realization is controlled automatically, operational management is simple.Since the eighties, this technology more and more comes into one's own, and becomes one of focus of research.In actually operating, because content of microorganisms is higher in the biological reaction tank, these microorganisms easily are attached on the film surface, and this easily produces membrane module and pollutes, in case film is contaminated, the filtration efficiency of sewage will reduce, even causes the damage of membrane module.In the present various types of films bio-reactor of developing, the pollution of film and obstruction are difficult problems always, therefore how to slow down to greatest extent the pollution of film and stop up the project of the always development research of worker that also is this technical field.
Summary of the invention
In order to improve existing technical disadvantages, the invention provides a kind of membrane bioreactor, this membrane bioreactor can slow down pollution and the obstruction of film to greatest extent.
For achieving the above object, concrete scheme of the present invention is:
A kind of membrane bioreactor, comprise biological reaction tank, membrane module, Controlling System, the perforate membrane aeration tube, the Biological drilling aeration tube, described membrane module is positioned at described biological reaction tank, described perforate membrane aeration tube is positioned at the below of membrane module, described perforate membrane aeration tube is connected by pipeline film aeration valve and the first air pump outer with being positioned at biological reaction tank, described Biological drilling aeration tube is positioned at the bottom of the pond of biological reaction tank, described Biological drilling aeration tube is connected by pipeline bio-aeration valve and the second air pump outer with being positioned at biological reaction tank, described membrane module is connected by pipeline clarified water pump and the water purification valve outer with being positioned at biological reaction tank, described water purifying valve door is connected with clear water tanks by pipeline, upper surface at described membrane module is fixed with vibrator, described Controlling System and this vibrator control linkage.
The stirring rake that is fixed in rotating shaft is arranged in described biological reaction tank, and the output terminal of the motor that described rotating shaft is outer with being positioned at biological reaction tank is connected.
