Description
Technical field
The invention belongs to environmental technology field, relate to sewage disposal technology, relate in particular to device and the treatment process thereof of utilizing little algae to dispose of sewage.
Background technology
Water is the most basic natural resources that the mankind depend on for existence, is that other any resource institute is irreplaceable.China is the country of a lack of water, and water resources ownership per capita approximately is 25% of a world average level, and along with expanding economy, water shortage status also will be more and more serious.Therefore,, effectively save existing water resources, keep sustainable economic development, must adhere to optimizing the cycling and reutilization road of water and water in order fundamentally to solve water shortage problem.And the water surrounding that worsens has day by day more aggravated to utilize the deficiency of water resources, more and more becomes the important restraining factors of economy and social development.Thereby treasure water resources, and set up the water prevention and cure of pollution system, containment water environment degradation trend seems very urgent.
Simultaneously, China is one of the most serious country of environmental pollution in the world, the annual sewage discharge in the whole nation reaches 36,000,000,000 tons, and wherein only 10% sanitary sewage and 70% trade effluent obtain handling, and have the water outlet of half industrial sewage treatment facility not reach discharging standards approximately.Other raw sewerage directly enters rivers,lakes and seas, causes the water surrounding of China to suffer severe contamination and destruction.Some geographic drinking water sources are subjected to severe contamination, and people ' s health is caused serious harm.
The river,lake and reservior water pollution of China mainly comprises nutrition and Organic pollutants two aspects such as nitrogen phosphorus.The pollution in water body of total nitrogen, total phosphorus can cause the eutrophication of water body, causes " wawter bloom " or " red tide ", also causes serious harm for waters ecology, life production and HUMAN HEALTH.For the control of eutrophication, developed country takes the technological line of " high strength pollution treatment-natural, ecological recovers " mostly based on control nutritive salt, promptly controls external source and pollutes input and cooperate the ecological recovery measure, has obtained big effect in this respect.Contaminated river,lake and reservior water body is repaired and reduced the discharging of pollution in environment has been pressing for of socio-economic development and improvement of the ecological environment.
Sewage mainly adopts anaerobism or aerobic microorganism degradation technique except that the organism in the decontaminated water at present, therefore still contain excessive nitric acid, salt ammonia and phosphoric acid salt in the sewage of handling, so the problem of the further denitrogenation of water and dephosphorization becomes the difficult point and the emphasis of domestic and international research after the waste water second-stage treatment.If adopt physics or chemical process to remove these ions, the one, cost very Senior Two is to cause the waste of secondary pollution and these nutritive substances easily.The denitrification dephosphorization technique that the sewage work of China design is at present adopted mainly by the removal of polyP bacteria at the circulation realization phosphorus of anaerobic and aerobic, is realized denitrogenation by nitrifier and denitrifying bacteria.Existing each technology all comprising space or time go up anaerobism, anoxic, aerobic three kinds of states alternately, because every kind of bacterium has different needs to nutritive substance and growth conditions, and different microorganisms all will participate in the high-efficient denitrification and dephosphorization flow process of system, therefore will guarantee that all microorganisms are impossible, this system that just makes is difficult to reach efficient operation.And exist complex process equally, need artificial inflation or add organic carbon source, and cause the waste of nitrogen phosphorus nutrition.In recent decades, the secondary that utilizes little algae to handle to contain nitrogen and phosphorus and three grades of sewage because have less investment, cost is low and characteristics such as easy operation, more and more caused people's attention and obtained extensive studies.Many studies show that, many little algaes can effectively absorb and assimilate nutritive ingredients such as nitrogen in the water and phosphorus in process of growth, therefore have and handle the possibility that contains compositions such as nitrogen, phosphorus, can remove the organism in the decontaminated water simultaneously, the mechanism of algae purification water quality is to oxygen supply of water body by photosynthesis, increase the dissolved oxygen of water body, make aerobic bacteria can constantly carry out degradation of organic matter, algae then utilizes the organic CO that produces of degradation by bacteria
2In addition, little Trentepohlia in a class species diversity complexity, also do not obtain the Biological resources developed far away, combination that therefore can be by screening different little algae strains, little algae and little algae and little algae combine with bacterium and handle specific sewage.Big quantity research shows that also little algae is handled the sewage that contains inorganic nutrients compositions such as nitrogen phosphorus except being used for, and little algae also might be used for handling the organic sewage of high density.Because algae can carry out photosynthesis, therefore, the construction costs that biology-ecological water body is repaired is relatively low, need not consume energy or low power consuming, and running cost is cheap.Have, required little algae kind has the advantages that the source is wide, breeding is fast again, for example can be under certain condition, to its screen, directed domestication, enrichment culture.In addition, this treatment technology can not form secondary pollution not to the water body delivering medicament.At last, as the autotrophy photosynthetic organism, can be used for producing biomass when disposing of sewage, the latter then can be applied to feed, the fodder additives of animal or be used for extracting fine chemical product and the new bio energy.The little algae that breeds after the sewage disposal can also be as rich biological food in the water, and the latter then can be directly as the fresh food of economic fishery products or through gathering processing.So, the sewage disposal work of the very suitable China of this cheap practical technique.
Though can use open cultivation pool, be that the so-called efficient oxidation pool (HROP) is cultivated little algae and handled agricultural, industry and municipal effluent, but because after sewage treatment process finishes, from the treated water body, reclaim little algae complexity very, therefore limited little algae in Application of Sewage.Three kinds of methods of main at present employing are removed the little algae in the water body: sand filtration method, centrifuging and chemical flocculation, these methods or efficient are low, cost is high, or generation contains the mud of little algae in a large number and produces secondary pollution.Therefore after utilizing little algae to dispose of sewage handling problem become and utilize dispose of sewage a big bottleneck of practical application of little algae, the researchist has proposed the notion that the employing immobilization technology is disposed of sewage for this reason.So-called little algae immobilization is cultivated, both utilizing before little algae disposes of sewage, be fixed on the little algae that is growing in certain matrix and then carry out sewage disposal and be considered to a kind of more feasible method, because after employing immobilization cultured microalgae is disposed of sewage and can be removed sewage disposal from, the separation problem of algae, water.All relevant little algae immobilizations are at present cultivated the processing aspect and all are in laboratory stage, and the kind of little algae of being studied is very limited, and not overripened.
