Description
Technical field
The present invention relates to a kind of waste water control way, be specially the method that a kind of high-effective microorganism thalline and zymin are disposed of sewage jointly
Background technology
Body eutrophication is the major cause of alga eruption.Nitrogen, phosphorus and organic carbon load are high in the water body, and accumulation surpasses the self-purification capacity of water body itself, breaks the stable eubiosis in the water body, cause algae and other planktonic organisms to breed rapidly, the water body dissolved oxygen content descends, water quality deterioration, fish and other biological mass mortality.At present, for polluted river channel and impounded body.Initial sewage disposal is adopted is extremely simple physics, chemical treatment facility, foreign material in the water are dammed through structures such as grids, and again through technologies such as flocculation sediments, sewage obtains preliminary treatment, but organism etc. can not get effective processing, treatment effect extreme difference in the water.Particularly along with industrial development, the composition of pollutent is day by day complicated in the sanitary sewage, and these pollutents cause the river black smelly after entering the ground water system.Science and technology development also makes sewage disposal technology constantly progressive simultaneously, and biological treatment now is because its good treatment effect and stronger practicality are widely used in wastewater treatment.In the water there be the existence form of nitrogen: ammonia, nitrite, nitrate and organonitrogen etc., efficient microbial strain contains various acidication enzymes, can rapidly larger molecular organics be cracked into the organic branch of small molecules, organonitrogen resolves into ammonia nitrogen, and efficient microbial strain passes through to the efficient absorption of ammonia nitrogen and the effect of nitrification and denitrification, with ammonia, nitrite, the nitrogen of nitrate form is decomposed into nitrogen, overflows from water.Excessive phosphorus is a principal element that causes algae outburst, and microorganism and bacterium are simple organisms in the water body, and its two basic characteristics are metabolism and breeding.And phosphorus is the essential composition of bacterial growth, be to constitute hereditary material DNA in the cell, and the key components of RNA, and DNA, duplicating of RNA pair cell is essential.
Administering the most popular technical scheme of polluted-water at present is to utilize extraordinary microorganism to administer water body, by different microorganisms the organic pollutant in the water body is decomposed to remove to sponge, a lot of about the technology report of this respect.Principle is by add efficient microbial strain in water body, process itself is process of growth absorbed nitrogen, phosphorus and organic carbon etc. efficiently, and the effect of process nitrification and denitrification, the nitrogen of the form of complexity is decomposed into the gasiform nitrogen molecule and escapes in the air, the mechanism of action of algae contention nutrient in realization and the water, thereby thoroughly interrupted the food chain of algae growth, made algae lack nutrition death, sunk under water; Efficient microbial strain continues the dead algae of degraded, makes water body become clear.The carbon (organic pollutant) and the combination with oxygen that are absorbed by bacterial cell membrane, sub-fraction becomes new cell paste, the overwhelming majority is decomposed into the digestible energy matter of bacterium under the enzyme effect, finally the form with carbonic acid gas discharges, thereby solves suspended solid and bed mud problem.
The stink of water body is produced by hydrogen sulfide, native smelly element and amine, and contaminated water body is taken off at the branch of efficient microbial strain, not only digests these odorous substances such as degraded hydrogen sulfide, quickens the circulation of ammonia, strengthens the speed that ammonia is converted into nitrogen; And can degrade and be deposited on the settling that the bottom produces native smelly element, utilize the ecological niche competition to suppress to produce the breeding growth of the unwanted bacteria of these materials in addition, thereby thoroughly solved the problem of stink.
Existence has thousands of different types of bacterium in the physical environment, and major part has kept unique digestion method of bacterium.Yet, for any bacterium, can only in some particular environment, could grow, as specific food or unique biological function.As a rule, natural bacterium does not have enough density to go to produce a complete or effect rapidly, " indigenous flora " at all just can't degrade dirt of special type.Therefore, we can introduce more microorganism and nutrition and develop and quicken the process that nature is repaired.
Efficient microbial strain water ecology recovery technique is the best approach of administering river course, lake view alga eruption.Can reach the effect for the treatment of both principal and secondary aspect of disease.Utilize the problem of the benign cycle solution body eutrophication of natural biology on the one hand, eliminate bed mud and pollutent on the other hand, the nutrition of cutting off source of pollution discharges, and adjusts biological growing environment, reaches pollution treatment purpose truly.
Microbiology shows, the help digest specific enzyme of food of all natural generation of all bacteriums.Enzyme resolves into the edible form of bacterium with food source.The product of " bacterium prescription " or " the diseaseful prescription of enzyme " (self-produced enzyme of all bacteriums in fact) relies on bacterium generation enzyme itself to carry out work.The product of only using " enzyme " food source can only be converted into simpler form but not complete digestion is so just shirked next level and caused more serious secondary pollution problem.So suitable microorganism strains is combined preparation to be used with enzyme, can make both mutual supplement with each other's advantages, and the research of this respect also has relevant report, application number for example: 200810029836.9 disclose a kind of microorganism water purifying assistant and preparation method thereof and application, this microorganism water purifying assistant is that aspergillus niger is activated, enlarge, collect after the fermentation culture and cultivate dry materials, pulverize promptly.Microorganism water purifying assistant of the present invention contains high active cellulase, zytase, dextranase, proteolytic enzyme, hydrolases such as amylase and lipase can quicken decomposition organic in the sewage, improve water treatment efficiency, be applicable to the water purifying treatment of pond, sewage work, landscape water body etc.Microorganism water purifying assistant of the present invention can cooperate with water body purification with microbial water-purifying agent, and compared with independent use microbial water-purifying agent, the adding of water purifying assistant has improved the speed of water body purification greatly, and decontamination effect improving is showing.
