Description
Technical field
The invention belongs to sewage treatment area, it is related to a kind of water-treatment biological membrane reactor.
Background technology
In recent years, as China's economy is developed rapidly, the sustainable growth of simultaneous population, a large amount of pollutants are discharged into
In the earth's surface aquatic ecosystem such as rivers and lakes, river basin ecological environment is caused to be destroyed, it is serious to restrict the sustainable of economic society
Development, influences the quality of life of people.The continuing to develop to be had become with engineer applied of sewage disposal technology maintains social economy
The necessary component of sustainable development.Various sewage treatment process based on physics, chemistry and biology principle continuously emerge,
Wherein biologic treating technique is most widely used, and has become the prevailing technology of municipal sewage and organic industrial sewage treatment.
There is economic, effective, environment-friendly, non-secondary pollution due to biological prosthetic, and the money of pollution can be realized
Sourceization is utilized, and is reliable method.In biological renovation method, algae, aquatic animal and water plant, or based on aquatic
Though the artificial swamp or land system of plant have certain effect, its efficiency is low, it is poor to take up an area many, repairing effect.And use micro-
Biological method treatment, effect is good, efficiency high, especially biomembrance process therein to the removal efficiency of the Organic substance in water etc. that gives up compared with
Height, has been widely used in the processing procedure of water and waste water.With the breakthrough of supporting technology and material, in recent years
Biomembrane process has obtained the very big concern of numerous researchers and engineers and technicians, and development is quite rapid, to biomembrane feature
Understanding and fundamental research constantly deepen, existing actual process becomes better and approaching perfection day by day, while occurring in that the biology of various new
Membrane reactor technique and various group technologies, have gradually formed a set of more complete biomembrance process biologic process for treating sewage system
Row.
The type of known existing biofilms reactor has with technology：Ordinary biofilter (aerobic), high-loading logical filter
(aerobic), tower biological filter (aerobic), anaerobic biofilter (anaerobism), activated biofiler (aerobic), aerobe rotating disk
(aerobic), anaerobic organism rotating disk (anaerobism), submerged bacteria filter (aerobic), micro-pore film biological reaction device (aerobic), biological stream
Change bed (aerobic), gas stripping type biofilm reactor (aerobic), mechanical agitation bed (aerobic, anaerobism), anaerobic organism film expanded bed (to detest
Oxygen), MBBR (aerobic, anaerobism), complex biofilmreactor, activated sludge-biofilm reactor, sequence
Batch biofilm reactor, upflow anaerobic sludge blanket process-anaerobic biofilter, apposition growth Wastewater Stabilization Ponds, these technologies are all
In being widely used in engineering because of each exclusive characteristic.
The A of Chinese patent CN 105174436 disclose a kind of biofilm aeration reactor, and it passes through to add 2 groups of microorganisms
Filler makes water process reach a new standard, and two kinds of microbe stuffings can select aerobic microbiological, also may be selected one
It is anaerobe to plant as aerobic microbiological is another, and using 2 groups of microbiological treatment water bodys, COD is significantly lower than a kind of microorganism
The sewage for the treatment of, meanwhile, reactor is still as good as with traditional size, and treatment is substantially increased while floor space is not expanded
Effect.
The B of Chinese patent CN 102015551 provide a kind of biofilm reactor containing helical structure, biomembrane reaction
Device has helical structure wherein, for forming the spiral froth flow passage from air supply pipe to outlet so that pass through
The foam for causing air supply pipe to be supplied flows and improves oxygen transfer rate by increasing the residence time of foam.The biomembrane
The advantage of reactor is that microorganism is attached to the helical structure and biomembrane is formed on the helical structure, so that real
Microbial suspension growth and two kinds of conditions of attached growth of microorganisms, and the energy under conditions of not using energy to be stirred are showed
The concentration of oxygen in water is enough effectively improved, and can effectively improve and keep the concentration of microorganism.
The A of Chinese patent CN 102951735 disclose a kind of combined type baffling water-treatment biological membrane reactor, with water inlet
Mouth, delivery port and drain, its feature exist：In a pond body for rectangle, by influent stream dividing plate, going out to flow dividing plate, advection plate will be anti-
Device is answered to be separated into relatively independent anoxic zone, aerobic zone and advection area.The invention aerobic zone and anoxic distinguish independent control, can
Reduction is interfered, and more preferably, technique is easy to operation to treatment effect, may be used on the even industry of eutrophication water, breeding water body
Waste water it is biological prosthetic.
Specifically, biofilm reactor has the advantages that following aspects：
1) microbial variation, biological food chain length, and the microorganism that the generation time that can survive is more long；
2) microbial biomass is more, and disposal ability is big, and purification function is significantly improved；
3) sludge settling property is good, it is easy to which separation of solid and liquid, excess sludge production is few, reduces Treatment of Sludge and takes with disposal
With；
4) anti impulsion load, changes with stronger adaptability, and can process the sewage of low concentration to water quality, water；
5) it is easy to operational management, reduces sludge bulking problem.
But existing biofilm reactor there is also deficiency：The water process of the biomembrane composition on filler and its surface is constructed
Thing is easily blocked；Carrying out stilling need to be aerated in reactor when aerobic bacteria is processed, energy consumption is big；Aerobic, anaerobic bacteria typically can not be simultaneously
Depositing need to separate treatment etc..
Therefore, study it is a kind of can effectively purify waste water and do not block, energy consumption is small, low cost water-treatment biological membrane reactor
Have important practical significance.
