Technical field
The utility model belongs to technical field of sewage, relates to sewage disposal and reuse technology, specifically relates to a kind of compound aerobic membrane bioreactor waste disposal plant.
Background technology
Sewage disposal and reuse are the important effective measure of China's development and utilization water resources, and membrane bioreactor (MembraneBioreactor, MBR) be the efficient water treatment hi-tech of one growing up for 20 end of the centurys, sewage is by after Membrane Bioreactor for Wastewater Treatment, the activated sludge sewage disposal process that the water quality of its water outlet is compared traditional improves a lot, wherein several representational indexs are: BOD5 is lower than 10mg/l, ammonia nitrogen is lower than 10mg/l, COD is lower than 30mg/l, and turbidity is less than 5NTU.Can, for middle water reuse, realize the abundant recycling of water resources through MBR water body after treatment.The principle of work of MBR is to utilize the organic pollutant that in reactor, the aerobic microbiological of activated sludge culture comes to exist in degradation of sewage, simultaneously, in reactor, also can produce nitrobacteria, these nitrifiers can convert ammonia nitrogen to nitrogen, reach the object of eliminating C source and N source.
As efficient Novel sewage treatment technology, compared with traditional biological process of wastewater treatment, there is effluent quality good, floor space is little, activated sludge concentration is high, and processing efficiency advantages of higher will have very wide prospect in biological degradation and the reusing sewage field of sewage.
Although MBR has the incomparable advantage of many other sewage treatment process, in the sewage disposal of sludge concentration, film pollution cleaning and high density, still there is the restriction of certain degree.Though the residence time that can effectively separate muddy water of MBR technique, but but mud is dammed completely in reactor, cause like this sludge concentration in reactor to increase, such increase will cause the pollution level aggravation of film, too much floc sludge will stop up the table hole of film, increase the operating pressure that water pump, cannot work too greatly until take out pressure.At this moment just need to clean film, no matter the cleaning charge of film is in adopting, to clean or outer way of cleaning, and cost is all quite high.Meanwhile, for the sewage of high density, even if MBR possesses good processing power, the water quality of water outlet also can reduce.
Utility model content
In order to address the above problem, the utility model provides a kind of compound aerobic membrane bioreactor waste disposal plant, thus the self-cleaning on acquiring a certain degree and blowdown, and the effect of raising water treatment quality.
The utility model is achieved by following technical solution.
A kind of compound aerobic membrane bioreactor waste disposal plant, comprise pneumatic pump, intake pump, go out water pump, film chamber, spillway, mud discharging mouth and reaction chamber, described spillway is positioned at reaction chamber upper end, described mud discharging mouth is positioned at reaction chamber bottom, described reaction chamber bottom is provided with distributed aeration opening and water-in, and be communicated with pneumatic pump and intake pump respectively, above aeration opening and water-in, there are some granular carriers, carrier top is set the biological filter screen of the biological filter screen of layer and upper strata successively, described upper strata biological filter guipure has centre hole, described film chamber is arranged in the centre hole of the biological filter screen in upper strata, described film chamber inner chamber with go out water pump and be communicated with, between the outer wall in film chamber and the centre hole of filter screen, leave spacing.
The inner side of the biological filter screen in described upper strata is downward-sloping; Described mud discharging mouth is downward-sloping funnel-form; The material that described carrier adopts density to be less than water is made, and surface irregularity.
The beneficial effects of the utility model are:
The compound aerobic membrane bioreactor waste disposal plant of one described in the utility model, by the biological filter screen of lower floor is set at the middle part of reactor, the further organism in degradation of sewage of the aerobic film forming on its surface, and the carrier of its below is intercepted, realize tentatively filtration; The biological filter screen in upper strata that is positioned at the inclination on reactor top, allows current and bubble that film chamber outside surface is formed and to be washed away, and reduces adhering to and the obstruction in aperture of impurity, reaches and reduces the effect that film pollutes; Upper strata biological filter has also adhered to aerobic microbiological on the net simultaneously, and these microorganisms reach further biodegradable effect to the sewage of low concentration after the biological filter screen of lower floor, effectively reduce the segregational load of film.
In addition, granular carrier surface also can form aerobic film by attached microbial, due to oxygen transmit effect, carrier granule has formed the system of a set of aerobic-anaerobic from outside to inside, this individual system can make internal layer microorganism because of anoxic automatically from carrier surface come off, sedimentation; Water inlet and the aeration of bottom are distributed water distribution and gas distribution, have effectively improved the contact area of sewage and air, realize and fully mix and contact in reaction chamber; The mud discharging mouth structure of bottom angled, can effectively discharge the microorganism losing vigor coming off from carrier granule, reaches the effect of controlling microorganism concn.
