Abstract
A two section type dynamic membrane bioreactor belongs to the technical field of organic waste water treatment devices. The utility model is mainly composed of a shell body, a water inlet, a water outlet, a membrane assembly and an aeration device, wherein the water outlet is arranged at the upper part of the shell body, the water inlet is arranged at the lower part of the shell body, the membrane assembly is arranged at the upper part of the inner part of the shell body, the aeration device is installed below the membrane assembly, the middle part of the inner part of the shell body is provided with a perforated plate, a plurality of sloping plates are uniformly arranged below the perforated plate and the inner part of the shell body has an upper part and a lower part. The membrane assembly is composed of bolting silk and an iron wire mesh, wherein the iron wire mesh is coated by the bolting silk; thereby, a sealed cavity is formed. The aeration device is a small air pump. When the utility model is used, the utility model has the advantages that high concentration organic waste water can be treated with high efficiency, organic waste water which has difficulty in degradation is effectively treated, membrane pollution is slowed down, the backwashing operation is reduced and the structure is reasonable.
Description
Technical field
The utility model relates to a kind of treatment facility of organic waste water of processing organic waste water equipment, especially high-concentration hardly-degradable.
Background technology
The bioreactor of dynamic membrane of using all is that a baffle plate is set in reactor at present, and baffle plate is divided into two portions with reactor, and two portions all communicate up and down.Membrane module at one end is housed, and the other end water inlet is at the feed-water end aeration, for mixing sludge provides oxygen and plays and impel the effect of mixed solution round-robin.When reactor water outlet pressure head is excessive, at the empty aeration of membrane module bottom, clean, to destroy the cake layer of Dynamic Membrane, reduce membrane resistance, and then reduce the water outlet head.When reactor water outlet pressure head is excessive, at the empty aeration of membrane module bottom, clean, to destroy the cake layer of Dynamic Membrane, reduce membrane resistance, and then reduce the water outlet head.
The shortcoming of said apparatus is: mixed solution is not enough to washing away of Dynamic Membrane, causes that easily film pollutes because film cleaning reaction device need shut down, after cleaning the decubation of Dynamic Membrane effluent quality relatively poor.And the reactor of above-mentioned structure only be fit to be handled the organic waste water of the easy degraded of lower concentration, is intractable for the organic waste water of the difficult degradation of high density.
Summary of the invention:
Above-mentioned prior art causes the film pollution easily and to the unmanageable defective of high concentration hard-degraded organic waste water, the utility model provides a kind of two-part bioreactor of dynamic membrane that can solve membrane pollution problem and can efficiently handle high density, organic wastewater with difficult degradation thereby in order to overcome.
The purpose of this utility model is achieved through the following technical solutions:
This two-part bioreactor of dynamic membrane, mainly form by housing, water-in, water outlet, membrane module and aerating apparatus, wherein, water outlet is on the top of housing, and water-in is in lower part of frame, membrane module is on the intravital top of shell, it is characterized in that aerating apparatus is installed in the below of membrane module, be provided with porous plate at the intravital middle part of shell, several swash plates are evenly arranged in the below of porous plate, go to upper and lower two portions in the housing.
Described membrane module is made up of bolting silk and wire netting, and bolting silk is wrapped in the wire netting outside, forms a sealed hollow.
Described aerating apparatus is a small air pump.
Described housing is cylindrical.
The utility model is placed on membrane module in the reactor, sets out the mouth of a river in the lower end of membrane module, utilizes flexible pipe to draw reactor, like this, utilizes the pressure reduction water outlet of reactor liquid level and water outlet.Because more about about 100 microns of the aperture of bolting silk has a lot of mud outflow reactors; Utilize the big mud of particle to be dammed, form sludge blanket, filtered about 2 hours, just form the Dynamic Membrane that forms by cake layer and gel coat on the bolting silk surface.Along with the prolongation of time, the aperture of bolting silk can become littler and littler, thereby improves the water quality of water outlet.The below of membrane module is provided with aerating apparatus, and purpose is to increase the washing away and disturbance of film, and effectively decelerating membrane pollution reduces backwash operation, increases the stability of reactor, effective decelerating membrane pollution.
Working process: in use, reactor is intake from lower water inlet, and waste water is hydrolyzed acidifying in the bottom, and waste water is carried out pre-treatment, hardly degraded organic substance is resolved into small molecules be easy to the organism that decomposed by aerobic bacteria, and can play the effect that reduces organic concentration.Bottom mud is filtered by porous plate after sloping plate deposition, and water outlet enters top by aerobic treatment.The top mixing sludge filters water outlet through membrane module under the effect of pressure reduction between liquid level and the water outlet.The aerating apparatus of membrane module below provides oxygen for the top mixed solution on the one hand, promotes mixed solution to flow on the other hand, and the mobile increase by bubble and mixed solution is washed away and disturbance film, reaches the purpose of effective decelerating membrane pollution.
Use the utility model, but can handle efficiently high concentrated organic wastewater, effectively handle the organic wastewater with difficult degradation thereby decelerating membrane pollution, reduce backwash operation, and have advantages such as rational in infrastructure, that effect is remarkable.
