Description
Technical field
The present invention relates to sewage microbiological treatment technical field, more particularly to a kind of NAS solidified carriers microbe generator
And the technology of the generator treated sewage.
Background technology
Sewage microbiological treatment technology, which mostly uses greatly, at present periodically launches microbial bacterial agent or the micro- life of activated sludge process culture
Object, the method for periodically launching microbial bacterial agent have that duration is bad, system is unstable, is easy to run off, is subject to be damaged, operate and answer
Miscellaneous, the problems such as Meteorological is larger.Activated sludge process is a kind of Aerobic biological process method of sewage, by the Clarke of Britain
(Clark) it about invented and applied in Mancunian Lao Lunsi sewage experiment station in 1913 with Gage (Gage).Nowadays, active
Sludge and its derivative improved process are the most widely used methods of treated sewage.It can utilize the nutritive salt culture in sewage micro-
Biology, and by microorganism species degradable organic pollutant, there are the adaptability that concentration of wastewater changes not to receive by force, easily for this method
The destruction of malicious sewage, debugging operations are complicated, generate excess sludge, the problems such as operating cost is higher.
Activated sludge process is continuously mixed sewage and various micropopulations under conditions of artificial oxygenation,
Form micropopulation.Using the organic pollution in microorganism species degradation sewage, and pass through anaerobism, aerobic link reduction water body
In chemical oxygen demand (COD), biochemical aerobic (BOD), total phosphorus, total nitrogen and ammonia nitrogen etc..Contain a large amount of disease in residual active sludge
The harmful substances such as bacterium, heavy metal, belong to high-risk waste, and when processing need to carry out sludge dehydration and safe disposal, time-consuming and laborious.
It is solid that nonactive sludge (non-activated sludge NAS) is had developed for above-mentioned problem inventor
Change carrier microorganisms generator, having long-term in the case where not adding any substance and material can sustainedly and stably provide height
Concentration microorganism species make polluted-water obtain the effect of the organic pollutant degradation of continuous and effective.
Invention content
The object of the present invention is to provide a kind of solidified carrier microbe generator and using generator treated sewage technology,
With long-term in the case where not adding any substance and material can sustainedly and stably provide high concentration microorganism flora, make dirt
Dye water body obtains the organic pollutant degradation of continuous and effective；Can be applied to lake, polluted river water administer, waste water of livestock poultry,
The processing of industrial wastewater, sanitary sewage；Activated sludge culture microorganism is utilized when can substitute traditional activated sludge process treated sewage
Key link, activated sludge is not generated in sewage disposal only, achievees the effect that sludge zero discharge.
The present invention above-mentioned technical purpose technical scheme is that：
NAS solidified carrier microbe generators, including the shell of tubbiness, the shell upper end are equipped with lid, the shell
Interior bottom is fixedly connected with the first aeration tube through lid, characterized in that is equipped with through-hole through the shell；The inner walls
Microorganism solidified carrier is filled between the first aeration pipe outer wall；
The microorganism solidified carrier is to utilize pottery mud and diatomite in mass ratio 50:1 1-5cm fired after mixing
Porous ceramic film material, a concentration of 1 × 10 will purified from nature by absorption, covalent bond, embedding skill means7CFU/ml's
It is Blastocystis, actinomyces, genus lactubacillus, photosynthetic bacteria, gemma Pseudomonas, nitrifier, denitrifying bacterium, nitrite-oxidizing bacterium, slender
The assembly of born of the same parents bacterium and transferase cures in carrier.
Further：Utilize the method for NAS solidified carrier microbe generator treated sewages, characterized in that including following
Step：
Solidified carrier microbe generator is placed in polluted-water by S1；
Aerator is arranged in S2, solidified carrier microbe generator lower end, forms aerobic zone；
After sewage flows through solidified carrier microbe generator, haptoreaction is carried out with the microorganism of release by S3.
By using above-mentioned technical proposal, more traditional activated sludge process or periodically add microorganism species treated sewage and
Speech, instead of traditional link by activated sludge culture microorganism or the regular link for launching microorganism species, effectively
Avoid activated sludge generation and follow-up microorganism addition launch, ensure that microorganism species required concentration and duration,
Stability can be effectively treated the sewage that pollution concentration changes greatly, realize the zero-emission of activated sludge, save
Handle human and material resources, the financial resources cost of activated sludge.
Further, second aeration tube is located at below carrier microorganisms generator, and second aeration tube away from
It is 40-200cm with a distance from the bottom of aerobic zone.
In conclusion the invention has the advantages that：
One, can without the other consumptive materials of any addition to polluted-water provide it is long-term, continue, stablize it is a variety of
Microorganism species for organic pollutant degradation；
Secondly, adapt to during microorganism species are provided different pollution concentrations sewage and the short time it is toxic
Sewage, and can effective degradation of contaminant；
Thirdly, do not generate activated sludge in sewage disposal only, achieve the effect that sludge zero discharge.
