Description
Technical field
The utility model relates to the technical field of reactor, especially a kind of anaerobic combined reactor.
Background technology
Anaerobic biochemical treatment is when anaerobic isolation or anaerobic, carries out biochemical decomposition, organism is transformed into methane and carbon dioxide gas, represents with following formula by anerobe:
Organic anaerobic digestion process divides two stages to carry out, i.e. acid fermentation stage and the alkaline fermentation stage, in the acid fermentation stage, in waste water, complicated organism resolves into better simply organism under acid formers effect, as organic acid, alcohols, C02, NH3, H2S etc.
The mechanism of anaerobic digestion: the mud outward appearance after acid digestion, in yellow or lark, compares thickness and not easily dewaters, is still easy to corruption smelly.The methanogen found belongs to methanococcus, eight folded methanococcus and Methanobacteriums.The feature of Methanobacterium is: 1. more weak to the adaptability of pH value, and the scope of adaptation is 6.8 ~ 7.8, and best pH value is 6.8 ~ 7.2; 2. more weak to the adaptability of temperature, according to the subject range to temperature, methanogen can be divided into middle temperature (30 ~ 35 DEG C) and high temperature (50 ~ 60 DEG C) two classes; After methanogen is tamed in certain temperature, temperature increase and decrease pressure 2 DEG C just may destroy methane digestion, particularly high-temperature methane bacterium, and temperature increases and decreases 1 DEG C, just likely digestive process is destroyed, and therefore methanogen requires to keep homo(io)thermism; 3. the generation of methanogen all comparatively, generally about 4 ~ 6 days breeding generation; 4. methanogen is very strong, and often kind of methanogen can only metabolism substrate undetermined, and therefore, under anaerobic, organic substance decomposing is incomplete often.
But traditional anaerobic reactor has following characteristics: a, organic loading are low, take up an area large; B, biomass are little, and biological activity is low, and capacity of resisting impact load is weak; C, function singleness, only have biological degradation function or filtering function usually.
Utility model content
The technical problems to be solved in the utility model is: in order to solve the prior art Problems existing in above-mentioned background technology, a kind of anaerobic combined reactor is provided, the structure adopting upflow anaerobic sludge expanded bed to combine with anaerobic filter, can give full play to both advantages.
The utility model solves the technical scheme that its technical problem adopts: a kind of anaerobic combined reactor, comprise reaction box, vertical biogas generator is provided with in described reaction box, biogas is passed into bottom it from the top of reaction box by biogas generator, the nearly top of reaction box is provided with anaerobic filter and is positioned at the water outlet above anaerobic filter, the bottom of reaction box is provided with water-in and is filled with by water-in the digester that water formed, and forms upflow anaerobic sludge expanded bed between described anaerobic filter and digester.
Further, the anaerobic filter described in technique scheme is stacked up and down by several inverted-V-shaped frids and forms, and several inverted-V-shaped frids are mutually permanently connected by some pieces of web plates.
Further, the water inlet described in technique scheme is provided with into water divider.
The beneficial effects of the utility model are: this anaerobic combined reactor, and the structure adopting upflow anaerobic sludge expanded bed to combine with anaerobic filter, can give full play to both advantages, have the following advantages:
One, organic loading is high, takes up an area few;
Two, biomass is large, and biological activity is high, and capacity of resisting impact load is strong;
Three, there is the dual-use function of biological degradation and filtration;
Four, filler is conducive to the quick generation of granule sludge.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Label in accompanying drawing is: 1, reaction box, 2, vertical biogas generator, 3, anaerobic filter, 31, inverted-V-shaped frid, 32, web plate, 4, water outlet, 5, water-in, 6, digester, 7, upflow anaerobic sludge expanded bed.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The utility model anaerobic combined reactor as shown in Figure 1, comprise reaction box 1, vertical biogas generator 2 is provided with in reaction box 1, biogas is passed into bottom it from the top of reaction box 1 by biogas generator 2, the nearly top of reaction box 1 is provided with anaerobic filter 3 and the water outlet 4 be positioned at above anaerobic filter 3, the bottom of reaction box 1 is provided with water-in 5 and is filled with by water-in 5 digester 6 that water formed, and forms upflow anaerobic sludge expanded bed 7 between anaerobic filter 3 and digester 6.
Wherein, anaerobic filter 3 is stacked by several inverted-V-shaped frids about 31 and forms, and several inverted-V-shaped frids 31 are mutually permanently connected by some pieces of web plates 32.Water-in 5 place is provided with into water divider.
The cultivation of the methanogen in this anaerobic combined reactor is as follows with domestication step:
By the old mud in pond, the kind mud as far as possible used, with to process kind of waste water consistent, makes the environment residing for granule sludge consistent, drop in reaction box 1, dosage accounts for 1/10 of digester useful volume, then adds fresh sludge to water outlet liquid level, maintains 35 DEG C of temperature to 3 ~ 5 day; If mud is in acid, alkali adjustment pH value to 6.5 ~ 7.5 manually can be added; After mud maturation, then carry and join fresh sludge and proceed to commencement of commercial operation.Heat-up rate during sludge acclimatization need keep 1 DEG C/h, until reach 53 DEG C.After reason is that temperature is more than 38 DEG C, middle temperature methanogen is resisted, and mortality, mud is souring very easily; If continue the temperature of maintenance 1 DEG C/h, do not have dead mesophilic bacteria strain can send out high yet; If heat-up rate is too slow, be then warmed up to 53 DEG C, also difficulty is recognized and is carried out normal thermophilic digestion.
The Operation and management of this anaerobic combined reactor: a, normal operation and laboratory indexes: water ratio 94% ~ 96%; Organic content 60% ~ 70%; Organic substance decomposing degree 45% ~ 55%; PH=6.5 ~ 7.5; Lipid acid is about 2000mg/L; Total alkalinity is greater than 2000mg/L; Ammonia nitrogen 500-1000mg/L; B, normally run Con trolling index: fresh sludge dosing rate, digestion temperature all should strictly control; First should discharge spoil disposal after supernatant liquor, to keep digested sludge concentration to be not less than 30g/L, otherwise digestion is difficult to carry out; C, maintenance and management: must not leaking-in air, to ensure methanogen and normal activity; In pond, scum silica frost and sand setting should regularly be removed, and within best 3 ~ 5 years, remove once; Be in operation and must take into full account the problem of taking care, because biogas is flammable explosive gas, when the aerial content of methane reaches 5% ~ 16%, meet naked light namely to explode, therefore around forbid or electric spark, in pond during maintenance, the digestion gas in pond must be got rid of completely.
Major failure and method for removing: a, gas production rate are low or not aerogenesis during the running of this anaerobic combined reactor: general employing stops dosing, adds alkali and regulates pH value, improves the ways such as surge capability and solves; There is negative pressure in b, pond: air will enter in pond in a large number, check whether shore pipe gate is closed tight.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on specification sheets, must determine its technical scope according to right.
