This invention is suitable for all kinds of waste water, comprises deodorizing, purification and the harmless treatment of city domestic sewage, trade effluent, livestock-raising field waste water; The purification of water quality of city river, blowdown pipe network, man-made lake, swimming pool, boat paradise, aquafarm etc.; Purify the water pollution in rivers, lake.
The product of this patent invention belongs to biotechnological formulation, contain definite chemical composition, microorganism used therefor all belongs to the probiotics useful to the mankind, therefore, people, animal, plant are perfectly safe, without any side effects, antioxidant that contains on the contrary and several physiological active substances are to the animal in the processing environment, useful coordination and the promoter action of plant.
In sewage treatment process, according to the nutritional condition in the external world, carry out the adjusting of bacterium internal energy, when extraneous nutritive deficiency, the bacterium internal energy reduces, and surface charge reduces, and the bonding force between the bacterium forms the suede grain greater than repulsive force, forms zoogloea; When external nutrition is enriched (sewage mixes the initial stage with active sludge, and F/M is bigger), the suede grain of formation disperses again, and then decomposes the various organic substances in the sewage.The beta-hydroxy-butanoic acid of bacterium cylinder accumulation is discharged into liquid phase simultaneously, also can make aggegation mutually between bacterium, forms the suede grain, and the viscous substance that the microorganism process of ingesting discharges also can promote aggegation.
Microorganism absorption pollutent mainly is the ion exchange by cytolemma, one netted peptidoglycan structure is arranged on the gram-positive bacteria cell wall, and there are teichoic acid or teichuronic acid to connect, phosphatide on it or carboxyl make cell walls electronegative, to the stronger absorbing power of positively charged ion tool in the sewage, and with positively charged contaminant ion generation permutoid reaction, pollution substance can be entered in the cell.Some active groups on the cell walls also have stronger complexing action, with particularly some macromolecular material complexings of pollution substance, make pollutant sediment at cell surface, and then, process body secretion exoenzyme etc. makes pollutent take place to transform or degraded.
The physiologically active substances such as coenzyme that produce in the composite bacteria metabolic process and discharge pathogenic former in the water body, as the equal certain restraining effect of tool such as Aeromonas hydrophila, Edwardsiella, mould, also can with the actinomycetes symbiosis in the water, make in the waters profitable strain propagation, suppress other pernicious bacterias breedings.
The entire sewage treating processes is actually with coagulation-deamination-biochemical treatment process and finishes.After microorganism ammonia nitrogen conditioning agent is thrown in, under the aeration situation, form a large amount of zoogloeas, various organic suspension things in the active adsorption sewage, and simultaneously it is decomposed, by a series of effects such as oxidation, ammonification, nitrated, denitrification, phosphorus decomposing, sulfurations, various organism and harmful pollutants can be decomposed into carbonic acid gas, nitrate, vitriol etc., reduce organic content and ammonia-nitrogen content in the water body, other chemical ingredients of Jia Ruing also has deamination simultaneously, also can improve the water quality of water body when decomposing mud.
Beneficial microorganism in the microorganism ammonia nitrogen conditioning agent at first is a decomposer to the decomposition of fermenting of organic and other pollutents in the water body, makes it innoxious.Then, the synthesis type microorganism utilizes its degradation production again, as NH

4, CO
2Deng, carrying out organic synthesis, larger molecular organics matter that is synthesized and microorganism coprecipitation become mud in the bottom, reach solid and liquid separation state, thereby reach the purpose of water purification.
Using this technology, at first is to make that beneficial microorganism quantity heightens in the water body, forms good waters micro-ecological environment.Then be planktonic organism and zootic increasing such as red worm, nematode, finally reach healthy and have the purpose that the fine water of vitality forms.Present technique is purified waste water is to recover and fortified water inherent oneself detergent power at all, forms health and is rich in the good water area ecological environment of vitality.
Probiotics is in finishing the water purification process, and the physiologically active substance of generation and antioxidant etc. all have good effect to animal, plant.The safety and Health of purifying waste water that utilizes this technology to produce can be used as farming, woods, herds, secondary, fishing and other every profession and trade water, improves the regeneration rate of water.
Advantage of the present invention is:
1. at the organic pollution materials that causes the water pollution major cause, filter out the strong microorganism of multiple specificity, water body is carried out the comprehensive regulation;
2. developed the compound cultivation technology of bacterial classification, made microorganism growth and breeding under same culture condition of multiple different genera;
3. utilize the composite curing technology, multiple composition is fixed on the special carrier, and made microorganism and metabolite mass-energy thereof in a relatively long time, play consistently effect, can be applicable to the processing of mobile sewage;
4. when water body is purified, can also effectively decompose mud, eliminate the root that causes water pollution;
5. applied widely, be suitable for all kinds of waste water, comprise deodorizing, purification and the harmless treatment of city domestic sewage, trade effluent, livestock-raising field waste water; The purification of water quality of city river, blowdown pipe network, man-made lake, swimming pool, boat paradise, aquafarm etc.; Purify the water pollution in rivers, lake;
6. the product of this patent invention belongs to biotechnological formulation, contain definite chemical composition, microorganism used therefor all belongs to the probiotics useful to the mankind, therefore, people, animal, plant are perfectly safe, without any side effects, antioxidant that contains on the contrary and several physiological active substances are to the animal in the processing environment, useful coordination and the promoter action of plant.
