Description
Technical field
The present invention relates to technical field for the treatment of of organic waste, in particular to passing through organic wastewater through continuous anaerobic fermentation reaction processes such as acidifying, neutralization, methanation and separation, the sludge quantity that process organic waste water is produced reduces, and obtain the good process water of water quality, promote a kind of high-level efficiency bio-hydrogen, the methane device of hydrogen and methane recovery amount simultaneously.
Background technology
When organic substance is in anaerobic environment, under certain temperature, humidity and potential of hydrogen condition, by the anaerobic fermentation effect of microorganism, biogas (biogas) can be produced.
The generation of biogas is the epochmaking ring of nature substance metabolism, and biogas main component is methane (methane, the CH of 50 ~ 80%
4) and 20 ~ 50% carbonic acid gas (CO
2), in addition also containing a small amount of carbon monoxide (CO), hydrogen sulfide (H
2s), hydrogen (H
2), oxygen (O
2) and nitrogen (N
2) etc. gas, due to containing high density inflammable gas methane (CH
4), therefore biogas can do fuel, biogas originates from the anaerobic fermentation process of organic waste water, produce the organism of biogas mainly from (garbage) more than kitchen, farm animal excrement (manure), organic waste water (organicwastewater), mud (sludge), agricultural waste (agriculturalwaste) or city waste (MSW) etc., and through anaerobically fermenting (AnaerobicFermentation) or be called " anaerobic digestion (anaerobicdigestion) " produce biogas energy processing mode be called methanation (methanation).
Tradition method for processing organic wastewater, be illustrated in figure 1 a kind of flowing-type anaerobically fermenting organic waste-water treating apparatus, this device mainly adopts flowing-type to design, organic waste water is entered fermenter T1 continuously, after staying for some time, the Digestive system of process is discharged together with microorganism mixed solution, and anaerobically fermenting react the methane that produces and carbonic acid gas and can be discharged to collect by end face and use.This kind of device, after Digestive system discharges together with microorganism mixed solution, the microbial bacteria concentration in fermenter T1 reduces, and methane phase efficiency is low.
Fig. 2 is a kind of return-flow type anaerobically fermenting organic waste-water treating apparatus, it mainly improves aforesaid method, the microorganism sludge will discharged together with Digestive system, after utilizing a settling bath T3 that microorganism sludge is precipitated, allows its backflow be mixed into fermenter T2 with waste water again.This kind of device, returns in fermenter T2 by precipitation foldback, thus can guarantee the residence time of anaerobion, make it again decompose as the matrix of anaerobion, improve digestibility (mud decrement rate), add the yield of methane.
Figure 3 shows that filtering type anaerobically fermenting wastewater treatment equipment, waste water mainly enters by bottom fermenter T4 by it, through some filtering layers T5, waste water rises to upper strata by bottom and flows out, filtering layer T5 is except filtering suspended substance, also there are many micropopulations in filtering layer T5, effectively can reach treatment effect rapidly, and produce methane and carbonic acid gas.This kind of device, is mainly retained in below filtering layer T5 by filtering layer T5 by anaerobion, promotes the residence time of anaerobion.
The anaerobic fermentation process of general generation methane has to pass through two main phase: the first stage is acidifying phase (acidificationphase) of sour generation phase, is organism complicated in waste water is converted into VFA (as acetic acid, propionic acid, butyric acid and alcohols etc.) by acidifying bacterium (acidogenicbacteria) and facultative bacteria (facultativebacteria); Subordinate phase is then for producing the methane fermentation phase (methanefermentationphase) of methane, aforementioned acetic acid and propionic acid metabolic reaction are produced methane and carbonic acid gas by the methanobacteria (methanogenicbacteria) utilizing acidization to produce, and sludge content in Digestive system is reduced.
Learn according to Research Literature, produce in methane factor at numerous anaerobically fermenting that affects, wherein:
1. temperature restriction: general anaerobically fermenting can occur between 50 ~ 60 DEG C, temperature claims thermophilic fermentation between 45 ~ 60 DEG C, mesophilic digestion is called between 25 ~ 45 DEG C, low temperature fermentation is called lower than 25 DEG C, leavening temperature is then called normal temperature fermentation with natural temperature change, usual leavening temperature is higher, and ferment effect is better.
2. biogas microorganism growth is slow: anaerobically fermenting utilizes fermenting bacteria decomposing organic matter, fill part and nutritive salt needed for anaerobic fermentation bacterial growth is provided, the biological sludge concentration in fermenter can be improved, to accelerate the carrying out of fermenting, and make up methanation bacteria growing shortcoming slowly, therefore the backflow of mud or filtration treatment are the method improving sludge retention time in fermenter.
3. need the long period to process: methanation (methanation) process, have to pass through about 0.5 ~ 2 day acidifying phase first stage (acidificationphase) (HRT) and about 2 ~ 7 days subordinate phase methane fermentation phases (methanefermentationphase) (HRT), make single groove process first stage acidifying phase (acidificationphase) and the time of subordinate phase methane fermentation phase (methanefermentationphase) longer, and cannot to process continuously.
4. organic concentration is too high: because the pH value of the VFA Digestive systems such as acetic acid, propionic acid, butyric acid and alcohols that acidifying phase first stage (acidificationphase) produces is between 5.0 ~ 6.5, and methane fermentation phase (methanefermentationphase) preferred concentration pH value is between 7.2 ~ 7.6, the processing efficiency making process acidifying phase first stage (acidificationphase) and subordinate phase methane fermentation phase (methanefermentationphase) produce methane reduces.
5. the nitrogen concentration of organic waste water is too high: concentrated waste also easily affects anaerobically fermenting efficiency, such as with Pig dung and urine water in anaerobically fermenting treating processes, Pig dung and urine must at least first dilute with the water of 3 times amount, makes its ammonia nitrogen concentration lower than 1, below 500ppm; General ammonia nitrogen concentration, 1, between 500 ~ 3,000ppm, can produce restraining effect for anaerobic bacterium, then produce murder by poisoning more than 3, more than 000ppm.
