Description
Technical field
The utility model relates to technical field of waste water processing, in particular to a kind of anaerobic reaction dress that water outlet heat recycles
It sets.
Background technique
China's water pollution problems is more serious at present, and it is important to pollute one for also paying close attention to and trying to solve as current people
Problem.In recent years, Anaerobic Digestion method, which develops to, is applied to processing high concentrated organic wastewater, as slaughterhouse water, meat add
Work waste water, sugar industry wastewater, alcohol industry waste water, packing industry waste water, sulphite pulp-making waste-water etc., than using aerobe
Object facture saves money.
Biological effluent treatment (biological treatment of waste water), to utilize the generation of microorganism
The effect of thanking removes a kind of method of Organic Pollutants in Wastewater, and also known as wastewater biological method of chemical treatment, abbreviation wastewater biochemical method is pressed
Its demand to oxygen is divided into aerobe facture and two kinds of Anaerobic biotreatment method.Aerobe facture is using aerobic
Organic pollutant in microorganism (mainly aerobic bacteria) Decomposition Wastewater, makes the processing method that waste water is innoxious.Its mechanism is,
After waste water is contacted with microorganism, dissolved organic matter in water through bacterium cell wall and cell membrane and be rapidly absorbed into bacterium
In vivo；Colloid and suspension organic matter are then attracted to phage surface, after being decomposed into deliquescent substance by the exoenzyme of bacterium,
Into in thallus.These organic matters are oxidized degradation by catabolic process in thallus, and the energy of generation is for bacterium life
Movable needs；A part of intermediate oxidation product becomes new cellular material by anabolism, enables bacterium growth and breeding.
The final product of processing is the stable inorganic matter such as carbon dioxide, water, ammonia, sulfate and phosphate.When processing, micro- life is supplied
Object is with elements such as sufficient oxygen and various necessary nutrient sources such as carbon, nitrogen, phosphorus and potassium, magnesium, calcium, sulphur, sodium；It should control simultaneously micro-
The life condition of biology, if pH is preferably 6.5~9, water temperature is preferably 10~35 DEG C etc..The active sludge of main method, biomembrane
Method, oxidation pond process etc..
From the aspect of cost, Anaerobic biotreatment method is most widely used.Anaerobic biotreatment method utilizes the micro- life of anaerobism
Object makes the method for purification of waste water with the organic pollutant in degrading waste water.Its mechanism is under the action of anaerobic bacteria by sludge
In organic matter decompose, finally generate the gases such as methane and carbon dioxide.Complete anaerobic digestion process can divide three phases: 1. dirty
Solid-state organic compound in mud is dissolved by means of the extracellular hydrolase secreted out of from anaerobic bacteria, and by cell wall into
Enter cell, under the catalysis of hydrolase, polysaccharide, protein, fat are hydrolyzed to monosaccharide, amino acid, fatty acid etc. respectively；2.
Under the action of acid-producing bacteria, the product of first stage is further degraded to better simply volatile organic acids, as acetic acid, propionic acid,
Butyric acid etc.；3. the volatile acid that second stage generates is converted to methane and carbon dioxide under the action of methane backeria.Influence factor
There are temperature, pH value, nutriment, organic poison, anaerobic environment etc..The advantages of anaerobic bio-treated, is the energy for the treatment of process consumption
Few, the removal rate of organic matter is high, and the sludge of precipitating is few and easy dehydration, can kill pathogen, be not required to add the nutrients such as nitrogen, phosphorus
Matter.But anaerobic bacteria breeding is slower, and it is sensitive to poisonous substance, environmental condition is required strictly, it is still necessary at aerobe for final product
Reason.In recent years, this method is commonly applied to the processing of high concentrated organic wastewater.
Major microorganisms in anaerobic digestion process include zymogenous bacteria (acidogenic bactria), hydrogen-producing acetogens, methane phase
Bacterium etc..Main fermentation and acid bacterium: fusobacterium, Bacteroides, Butyrivibrio, Bifidobacterium etc.；Hydrolytic process is relatively slow
Slowly, and it is (pH, SRT, organism kinds etc.) affected by many factors, the rate-limiting step as anaerobic reaction is returned sometimes；It is anti-to produce acid
The rate answered is very fast；Most of is anaerobic bacteria, and also having is largely facultative anaerobic bacteria；It can divide by function: cellulose-decomposing bacterium,
Hemicellulose decomposer, starch decomposer, protein decomposing bacteria, lipolysis bacterium etc..Main hydrogen-producing acetogenic bacteria is mostly:
Syntrophism zygosaccharomyces, syntrophism Bacillus, fusobacterium, dark Bacillus etc.；Majority is strict anaerobes or facultative anaerobic bacteria.Methane phase
The major function of bacterium is by the product of hydrogen-producing acetogens --- acetic acid and H2/CO2It is converted into CH4And CO2, make anaerobic digestion
Process is smooth；It can be divided mainly into two major classes: acetic acid auxotype and H2 auxotype methanogen, or produced for thermophilic acetic acid
Methane bacteria and thermophilic producing hydrogen and methane bacterium；In general, the type of acetic acid auxotype methanogen is less in nature, only
Methanosarcina (methane phase sarcine) and Methanothrix (methane phase der Pilz), but both methane-producing bacterias
In the majority in anaerobic reactor, especially the latter generally comes because acetic acid is main methane phase matrix in anaerobic reactor
The methane for saying 70% or so is the oxygenolysis from acetic acid；
In taxonomy, methanogen (Methanogens) belongs to archeobacteria (Archaebacteria), size,
It is similar to common bacteria (Eubacteria) in appearance, but in fact, its cell component is special, especially the structure of cell wall compared with
It is special；In the distribution of nature, can be generally considered as be inhabit in some extreme environments (as thermalwater, deep-sea volcanic crater,
Deposit etc.), but actually its distribution is extremely wide, such as sludge, cud, insect gut, wet trees, anaerobic reactor；It produces
Methane backeria is all strict anaerobe, it is desirable that oxidation-reduction potential has it in -150~-400mv, oxygen and oxidant very strong
Toxic action；The multiplication rate of methanogen is very slow, and the propagation generation time is long, up to 4~6 days, therefore, produces first under normal circumstances
Alkane reaction is the rate-limiting step of anaerobic digestion.
Influence of the temperature to anaerobe is especially pronounced；Anaerobic bacteria can be divided into Thermophilic Bacteria (or high temperature bacterium), mesophile
(mesophile)；Correspondingly, anaerobic digestion is divided into: thermophilic digestion (55 DEG C or so) and mesophilic digestion (35 DEG C or so)；Thermophilic digestion
Reaction rate be about 1.5~1.9 times of mesophilic digestion, factor of created gase is also higher, but methane content is lower in gas；When processing contains
When the waste water or sludge of pathogen and parasitic ovum, thermophilic digestion can obtain preferable hygiene effect, and sludge is de- after digestion
It is aqueous can also preferably.In anaerobic waste water biological treatment, its metabolism is vigorous at 37 DEG C or so for anaeration in normal temperature microorganism,
It is generally acknowledged that the activity in 20 DEG C or less methane backerias does not just have engineering significance.
And it is many in the low-temperature wastewater that practical anaerobic bio-treated engineering encounters, most of method is handled it
Main method is to rise to waste water temperature to 37 DEG C or so by the way that the measures such as steam are added, then carry out anaerobic organism reaction.By
Relatively good in the Insulation of anaerobic reactor, output water temperature varies less, probably at 35 DEG C or so.Anaerobic reactor it
After be typically provided an aerobic reactor, and requirement of the aerobic microbiological to temperature is not bery very high, general 10 DEG C to 15 DEG C just
It can satisfy its metabolic demand.In the prior art it is usually to flow directly to 35 DEG C of water outlet in aerobic reactor, largely effects on
Aerobic biological process ability in aerobic reactor, and waste the energy wherein contained significantly.There is presently no suitable
Technology the contained heat of these water outlets is used.
