Description
Technical field
The utility model relates to a kind of membrane bioreactor of effectively disposing of sewage, and belongs 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 is 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, also have some large suspended substances, these microorganisms are attached on the film surface easily, this produces membrane module easily and pollutes, and large suspended substance also can stop up the film tube passage very soon, in case film is contaminated or obstruction, 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 utility model provides a kind of membrane bioreactor of effectively disposing of sewage, and this membrane bioreactor can slow down pollution and the obstruction of film to greatest extent, effectively purifying treatment sewage.
For achieving the above object, concrete scheme of the present utility model is:
A kind of membrane bioreactor of effectively disposing of sewage, comprise biological reaction tank, the membrane filtration pond, membrane module, the perforate membrane aeration tube, the Biological drilling aeration tube, described membrane module is positioned at the membrane filtration pond, described perforate membrane aeration tube is positioned at the below of membrane module, described perforate membrane aeration tube is connected with film aeration valve and the first air pump outside being positioned at the membrane filtration pond by pipeline, 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 with clarified water pump and water purification valve outside being positioned at the membrane filtration pond by pipeline, described water purifying valve door is connected with clear water tanks by pipeline, be separated by by weir divider between described biological reaction tank and the membrane filtration pond, be fixed with two parallel screen clothes in the upper surface of weir divider, between described two screen clothes the space arranged.
