Affiliated technical field
The utility model relates to a kind of field of environment protection wall biosynthesis waste disposal plant.
Technical background
Can be divided into biological pollution in the occurring in nature environmental pollution, physical contamination and chemical pollution three major types, wherein particularly the organic chemistry pollution toxicity is heavy in chemical pollution, and it is wide to distribute, and quantity discharged is big, and ecotope is constituted greatly harm.But, also existing a large amount of dependence picked-up organism in physical environment is the microorganism that nutrition is survived, they can decompose, the most of organism of oxidation, not only be translated into stable new compound, and can toxic organic compound be converted into the inorganic nothing of toxicological harmless effect, discharge microorganism growth active energy simultaneously by metabolism, and a part of organism changed into the essential nutritive ingredient of organism, form new cellular material.
Biologic process for treating sewage is exactly to utilize this specific function of microorganism to realize the purpose of purifying waste water.The biological treatment of sewage is divided into aerobic treatment and anaerobic treatment two classes, the main removal that aerobe is handled to as if sewage in the organic pollutant of dissolving and colloidal, the main removal of anaerobic biological treatment is to liking the mud that produces in high concentrated organic wastewater and the sewage disposal etc.In aerobe is handled according to the microbial growth state, can be divided into two kinds of suspension growth and apposition growths, the former is representative with the activated sludge process, microorganism is that the active sludge form with suspended state exists, and the latter is representative with the biomembrance process, and microorganism is to exist with the form of mucous membrane shape attached to carrier surface.

Its principle of biomembrance process is by the aeration oxygen supply, activating microorganisms, make microorganism cells firm be adsorbed on carrier surface, and grow thereon and breed.In the microorganism cells outside the born of the same parents of outer stretching, extension polymer, make microorganism cells form the mucous membrane of fibrous winding arrangement, be called microbial film, when effluent stream during through the microbial film of carrier surface, microorganism is by the absorption to organic nutrient substance, dissolved oxygen is to the diffusion of microbial film inside, in a series of bio-oxidation Decomposition of the inner generation of microbial film.Biomembranous outermost layer forms is biostrome based on aerobic type microorganism, it is the main body of differentiation degradation of contaminant, and in the deep of aerobic layer because diffusion has restricted the penetrating power of dissolved oxygen, often form anaerobic layer, because the effect hydrogen sulfide of anerobe, materials such as ammonia and organic acid easily deposit.But anaerobic layer is compressed to certain limit under the competent condition of dissolved oxygen, and the RCOOH of formation is converted into CO under the effect of heterotrophic bacterium
2, and H
2O, and NH
3And H
2S is converted to various stable salts under the effect of autotrophic bacteria.Along with the microbial film sticking power that increases of anaerobic metabolism product weakens, aging coming off finished microorganism and changed from generation to generation, and new microbial film is born again, goes round and begins again to reach the purpose of defecate and purify sewage.Bio membrane process is stable, anti-shock loading, economical and energy saving, no sludge bulking, have certain nitrification and denitrification function, can realize that closed operation prevents peculiar smell.Also exist simultaneously biofilm carrier and select the problem of difficulty, because biofilm carrier is the core of bio membrane process, it directly influences the treatment effect and the operation control of this technology.At present, the most smooth surface of the rigid carrier of domestic common employing, microbial film poor adhesive force, biofilm cycle length, microbial film thickness are difficult to defectives such as control; The flexible carrier flow-shape is undesirable, easily cohered by microbial film and produce that caking, microbial film easily stop up, inner anaerobism influence treatment effect, wash problems such as difficulty.These traditional biofilm carriers exist certain defective just, have limited the application of bio membrane process in the wastewater treatment in China field.
