Abstract
Provided is an optimization culture method of biomembrane microfloras. The technological processes are as follows: first, a biofilter is back washed; second, the back washing water flows into an optimization culture tank; third, the culture tank is subjected to aeration culture at intervals, and nutriments are added; fourth, after culture is carried out for a certain time, a small amount of source water is added; fifth, after a certain time, cultured optimized microfloras are added into the biofilter through a pump; sixth, biofilm culturing is carried out, after a certain time, source water is injected gradually and trial operation is performed. The method has a scientific and reasonable whole design, has a simple structure and convenient operations, and has stable and reliable performances, high efficiency and strong practicability. The method is a key way for optimization culture of biomembrane bacteria in a biofilter, and also provides microflora optimization service for the activated sludge process and industrial waste water treatment.
Description
Technical field
What the present invention relates to is the optimization cultural method of flora, and concrete is a kind of sewage treatment industry, the optimization cultural method of the Bacterium of biofilm that biological filter is used.
Background technology
Biological filter process is a kind of biomembrance process being derived by activated sludge process.Appearance and development along with it, all occupy and consequence at various sewage treatment areas.The form in filter tank is, the kind of filler is constantly being upgraded and improving at present, and on microbial film, the optimization of flora also becomes the important subject in this field.The optimization of Bacterium of biofilm mainly proposes for alleviating the aging problem of microbial film.
Affect the situation more complicated that flora is aging, wherein several major causes are unbalance due to nutritive props in the microbial biomass on microbial film and water; Aeration time and intensity are unreasonable; The reason such as in water carbon-nitrogen ratio and carbon-phosphorus ratio be unreasonable.Because aging flora can adsorb much impurity, vitality is poor, and when running into while being not suitable for environment, flora will occur loose, even occurs single bacterium, and then affects biomembranous biochemistry and absorption property.Aging due to bacterium, also can produce biomembranously extremely come off, the problem such as microbial film anti impulsion load reduction, sewage treating efficiency is reduced, power consumption and cost increase, and affect effluent quality effect.
Summary of the invention
The object of the invention is the problems such as the Bacterium of biofilm that exists for current biological filter agingly, biomembranous comes off extremely, microbial film anti impulsion load is low, processing efficiency is low and provide a kind of simple, practical, Bacterium of biofilm is optimized cultural method efficiently.
The technical scheme adopting is:
An optimization cultural method for Bacterium of biofilm, is characterized in that comprising following technological process: 1, biological filter backwash; 2, backwash water flows into and optimizes cultivation pool; 3, cultivation pool is interrupted aeration cultivation, adds nutrition; After 4 cultivation for some time, inject small part source water; After 5 for some time, by pump, cultured optimize microbial groups is squeezed into biological filter; 6, start biofilm, after for some time, progressively inject source water and enter trial run.
Principle of work
Enter in the backwash water of optimizing cultivation pool and both contained the microbial film coming off, also contain the cotton-shaped walk between microbial film and filtrate.Utilize backwash water source both to embody the microorganism speciality of optimizing bacterial classification; Also the best that has guaranteed bacterium forms structure and existence thereof, development and fecundity process; The nutritive substance that the flora domestication stage in early stage is also provided simultaneously to be needed is supplied with, and will deal with source water quality impact get involved in advance adaptive state for flora.The object of injecting a small amount of source water waste water before importing biological filter is to make the new optimize microbial groups of cultivating adapt to gradually following waste water speciality to be processed, prevents that when flora from importing biological filter, the sharply variation due to environment causes optimization to be tamed unsuccessfully.
The present invention compared with prior art has the following advantages:
1, the present invention utilizes to optimize training method, by manual intervention and physical environment optimal way, selects good quality strain, makes its growth rapidly, breeding, and then makes the biological filter after biofilm more have vitality.
2, due to the best assembly of predominant bacteria, the surperficial pod membrane mean thickness that makes to be wrapped in outside filtrate guarantees at 0.5-2.0um, and microbial film is tightr than traditional, difficult drop-off.
3, due to tight type and the activity of dominant microflora, improved the anti impulsion load to water, reached the treatment effect of expection, efficiency at least improves 15%-20%, again cultivates the domestication time can continue more than 1 year.
Global design science of the present invention, reasonable, simple in structure easy to operate, stable and reliable for performance, efficiency is high, practical.The present invention optimizes the crucial mode of cultivating biological filter microbial film bacterium, also can be activated sludge process and Industrial Wastewater Treatment flora Optimized Service.It should be noted that: do not changing under the prerequisite of the principle of the invention and design, the change of having done or distortion all belong to protection scope of the present invention.

Embodiment
Embodiment
Design a concrete and cultivate domestication pool, according to the Microflora of cultivating, select the pond of corresponding size.The bacterial origin major part of optimize microbial groups is backwash water and the small portion source of sewage water of biological filter.First backwash water enters domestication pool by gravity flow, carries out the limited aeration of discontinuity therebetween in domestication pool.Because backwash water has experienced air-blowing, water washing process in backwash process, powerful power can be peeled the part diaphragm on microbial film off, the bacterial classification of the anaerobism originally having on this diaphragm, anoxic and aerobic layer also exists, and has guaranteed continuation survival and the breeding of these bacterial classifications by the aeration of discontinuity.Pass through purge, originally be adsorbed on broken the taking out of of cotton-shaped walk between microbial film and filtrate, the main component of this walk is source water component, part microorganism in component is in the endogenous respiration phase and subtracts the proliferation period back segment that declines, the flora of this part in the aged stage (must remove) in addition part microorganism just completed adsorption process, the also increment animated period of these microorganisms just while entering cultivation domestication pool.Backwash water, by after discontinuity period of aeration, starts to add continuation fertility, breeding and the metabolism that nutrition source guarantees bacterial classification.Aeration condition is constant.Flora after for some time in domestication pool has possessed the advantage of optimize microbial groups, now starts to inject a small amount of source water waste water.Finally mixed solution is carried and squeezed into biological filter by pump, by sneaking into gradually Yuan Shui, complete the biofilm again of biofilter material.Flora optimization cultivation and biofilm complete.The concrete technology step of the present embodiment is: 1, biological filter backwash; 2, backwash water flows into and optimizes cultivation pool; 3, cultivation pool is interrupted aeration cultivation, adds nutrition; 4, after cultivation for some time, inject small part source water; 5, after for some time, by pump, cultured optimize microbial groups is squeezed into biological filter; 6, start biofilm, after for some time, progressively inject source water and enter trial run.
