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 have 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 processing.
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 processing, effect is good, efficiency high, biomembrance process especially therein to the removal efficiency of the Organic substance in water etc. that gives up compared with
In height, the processing procedure for being widely used in 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
It is widely used in because of each exclusive characteristic in engineering.
The A of Chinese patent CN 105174436 disclose a kind of biofilm aeration reactor, and it is by adding 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
Kind be aerobic microbiological it is another be anaerobe, using 2 groups of microbiological treatment water bodys, COD is significantly lower than a kind of microorganism
The sewage of processing, meanwhile, reactor is still as good as with traditional size, and processing 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 being stirred without using energy 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 the pond body of a rectangle, by influent stream dividing plate, go out to flow dividing plate, advection plate by instead
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 longer；
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, and reduction Treatment of Sludge is taken with disposal
With；
4) anti impulsion load, changes with stronger adaptability to water quality, water, and can handle the sewage of low concentration；
5) it is easy to operational management, reduces sludge bulking problem.
But there is also not enough for existing biofilm reactor：The water process of filler and its biomembrane on surface composition is constructed
Thing is easily blocked；Still need to be aerated into reactor when carrying out aerobic bacteria processing, energy consumption is big；Aerobic, anaerobic bacteria typically can not be simultaneously
Processing etc. need to be separated by depositing.
