PH is down to 6.5 hereinafter, adjusting pH to 7.5-9.0 with lye.
In above-mentioned steps A, the nutrition salt component composition and relative scale are by weight are as follows: NaHCO38-32 parts,
K2HPO46.5-26 parts, NaCl1.5-6 parts, MgSO40.15-0.6 parts, FeSO40.15-0.6 parts;Using the nutrition of this composition
Salt can solve the single problem of black smelly water constituent, and the hot housing for nitrifying bacteria community in indigenous microorganism and seed sludge provides
Necessary nutriment accelerates the building of functional flora, wherein NaHCO3Inorganic carbon source needed for can provide nitrobacteria growth,
Promote its mass propagation.
In above-mentioned nutrient solution prescription, the inorganic carrier used is in the common inorganic carrier such as zeolite powder, diatomite, calcium carbonate
One or more of combinations, preferred zeolite powder;The addition of inorganic carrier can provide place for attached growth of microorganisms, to mention
High flora concentration, and why preferred zeolite powder, be because zeolite powder can not only as carrier for flora apposition growth, also have
There is excellent suction ammonia ability, the nitrifying bacteria community of its surface attachment will be supplied to degrade after ammonia nitrogen absorption, the training of nitrifying bacteria community can be improved
Treatment effeciency after supporting efficiency and investment application;In addition, there are also the works of suspended matter in absorption black and odorous water for the presence of inorganic carrier
With further purifying water body environment.
In the building process of above-mentioned compounding process and follow-up function flora, certain proportion waits administering in nutrient solution
Black smelly water is added to committed step, and the building process of functional flora can be made to be in former black and odorous water aquatic environment always, made
Functional flora, which is treated, administers the good adaptability of water body holding, is particularly advantageous to improve the nitrifier more sensitive to environmental change
Adaptability of the group when cultivating and adding application, make its always can under former black and odorous water condition of water quality efficient degradation ammonia
Nitrogen, and make its strain composition with the dynamic equilibrium shape of incubation and the former black and odorous water aquatic environment variation holding survival of the fittest
State;Therefore, no matter for which kind of black and odorous water, the step for being added wait administer black smelly water, may insure constructed functional flora
Always there is good applicability and specific aim, it can be made to adapt to the application environment corresponding to it respectively.
It is above-mentioned for prepare nutrient solution process, and the building of the process and entire functional flora in open environment into
Row is not required to the operation such as sterilizing, and there is no need to special installations, can be met using the simple culture vessel with aerator and be wanted
It asks, equipment cost is cheap, such as has ready conditions, and the dedicated culture device such as fermentor, fermentation vat can also be used.
In above-mentioned culture vessel, the biologic packing material of arrangement can be soft cellulose filler, semi soft packing, shield formula filler,
The sewage treatment fields such as biological cotton net commonly fix filler;Inorganic carrier and biologic packing material are used cooperatively, on the one hand can
The cell concentration of slow growth, nitrobacteria with apposition growth characteristic is greatly increased, enhancing adds application effect, another party
Face, the strain being attached on fixed biologic packing material can guarantee that the bacterium amount in culture vessel is in higher level, Bu Huiyin always
Adding and adding and causing being greatly decreased for bacterium amount when the later period is applied helps to carry out making when supplement culture after each
Functional flora restores rapidly optimum state.
In B. seeded process, since community construction process is amplified step by step, so initial nutrient solution volume accounts for and expects
The ratio of total volume of culture cannot be excessively high, it is generally preferable in 20-40%;The ratio of indigenous microorganism sample and seed sludge is 2:
1~5:1, flora source is based on indigenous microorganism, supplemented by seed sludge;Using indigenous microorganism as flora source, institute
The functional flora of building treat administer water body adaptability it is good, biological safety is good;Supplemented by seed sludge, main reason is that connecing
Kind sludge belongs to inoculating microbe, and adaptability is limited, but its activity and strain concentration are higher, therefore is conducive to accelerate the whole of flora
Body constructs process and improves overall activity.
In C. level-one culture, being carried out using the increased mode of ammonia-nitrogen content gradient, each gradient is kept for multiple periods, and
And do not add any organic carbon source, it is therefore intended that culture environment is gradually changed into the environment of low organic carbon, high ammonia nitrogen, is quickly washed in a pan
The heterotrophism miscellaneous bacteria that can not adapt to the environment in indigenous microorganism and seed sludge is eliminated, makes nitrifying bacteria community therein black smelly wait administer
It is gradually adapted in water environment and behavior of high-strength ammonium of degrading, mass propagation becomes dominant microflora.
In D. second level culture, the supernatant liquor of level-one nutrient solution volume 50-80% is discarded, is because by macrocyclic
Level-one culture may have accumulated the metabolite for largely having inhibiting effect to microorganism growth in culture solution, need to discharge it
Culture solution;Meanwhile culture solution spreading cultivation to estimated total volume of culture, the nitre of dominant microflora will be had become by being equivalent in level-one culture
Change flora and be used as strain, fast-propagation to the total amount for meeting requirement, this process can further promotion functions microorganism
Expand numerous, superseded miscellaneous bacteria.
In above-mentioned steps B-D, adjusting lye used in pH is the sodium carbonate of any concentration, sodium bicarbonate aqueous solution or both
Mixed solution (mass ratio is unlimited when mixing), which is not only able to adjust the weak base that needs to nitrifying bacteria community of culture solution pH
Property environment, basicity needed for supplementing, additionally it is possible to play the role of the inorganic carbon source of supplement, promote nitrifying bacteria community growth and breeding, therefore be
Construct most suitable lye when the functional flora based on nitrifying bacteria community.
In above-mentioned steps B-D, adjusting ammonium salt used in ammonia nitrogen is the cheap ammonium salt such as ammonium sulfate, ammonium chloride or ammonium carbonate, carbon
Sour hydrogen ammonium etc. can provide the combination of one or more of ammonium salt of inorganic carbon source and nitrogen source simultaneously, mass ratio when multiple combinations
It is unlimited.
In above-mentioned steps B-D, the terminal that each cultivation cycle terminates is reached by ammonia nitrogen and nitrite nitrogen removal rate
Determined to 90% or more, this decision procedure is different from existing the relevant technologies, and existing majority is using degradation of ammonia nitrogen as mesh
Bacteria group culture and microbial inoculum technology of preparing all only using ammonia nitrogen degradation situation as criterion, but the accumulation of nitrite nitrogen is not only
Bacteria group culture is caused to inhibit, the culture solution containing nitrite nitrogen, which is added, also will cause secondary pollution into water body, therefore this hair
It is bright that cultivation cycle terminal is determined by ammonia nitrogen and nitrite nitrogen dual indexes.
The building process of above-mentioned functional flora, strain composition keep excellent with incubation time and the variation of raw water body aquatic environment
Win the bad dynamic balance state eliminated, ultimately form the metastable efficient functional flora to raw water body with adaptability,
The advantage of the above method also resides in, can also be with the culture of flora for the function strain that traditional biological technology can not be separately cultured
Process advantages growth reduces the cost of Spawn incubation to utmostly play the processing capacity of indigenous microorganism.
