Abstract
The utility model discloses an anaerobic fermentation system for kitchen waste treatment, belonging to the technical field of environmental protection equipment. The system consists of a feed regulation pool, a primary anaerobic fermentation tank, a secondary anaerobic fermentation tank, a biogas lifting type enhanced reactor, a comprehensive pool and a biogas collection device, wherein a material enters the primary anaerobic fermentation tank and the secondary anaerobic fermentation tank respectively through the feed regulation pool; the yielding water after secondary fermentation enters the biogas lifting type enhanced reactor through the comprehensive pool; and the biogas generated by the primary anaerobic fermentation tank, the secondary anaerobic fermentation tank and the biogas lifting type enhanced reactor enters the biogas collection device. The system disclosed by the utility model has the advantages of simple structure and good treatment effect.
Description
Technical field
The utility model relates to a kind of changing food waste processing and uses anaerobic fermentation system, belongs to the environmental protection equipment technical field.
Background technology
At present, food wastes is carried out the anaerobically fermenting processing have certain development prospect, but also few for the anaerobic treatment equipment of changing food waste feature development.
The utility model content
The utility model provides a kind of changing food waste to process and has used anaerobic fermentation system, and concrete technical scheme is as follows:
A kind of changing food waste is processed and is used anaerobic fermentation system, it is characterized in that, is comprised of charging equalizing tank, one-level anaerobic fermentation tank, B grade anaerobic fermentation tank, biogas-lift reinforced reactor, comprehensive pool and sludge gas collecting device; Wherein, material enters respectively one-level anaerobic fermentation tank, B grade anaerobic fermentation tank through the charging equalizing tank, and the water outlet of B grade anaerobic fermentation tank enters biogas-lift reinforced reactor by comprehensive pool; The biogas that one-level anaerobic fermentation tank, B grade anaerobic fermentation tank and biogas-lift reinforced reactor produce enters sludge gas collecting device.
Further, the water outlet of B grade anaerobic fermentation tank enters comprehensive pool, and mud is got back to equalizing tank, thereby realizes the separation of mud, water.
Described charging equalizing tank operation scheme is intermittent operation, and its effect is to regulate input speed (10m
3/ h-20m
3/ h) and feeding temperature (40 ℃-70 ℃), make charging evenly controlled.
Described one-level anaerobically fermenting is used for degrading main solid substance, and COD was degraded in this stage, and biogas began to produce in this stage, controlled 30-60 ℃ of temperature, and pH is 7-8, and fermentation time is 15-20 days.
Described B grade anaerobic fermentation tank is controlled 30-60 ℃ of temperature, and pH is 7-8, and fermentation time is 10-15 days, and COD continued to be degraded in this stage.
Described comprehensive pool, for the treatment of the precipitation of fermentor tank water outlet, the water inlet of biogas-lift reinforced reactor is regulated in concentrating of mud.
Biogas-lift reinforced reactor is used for continuing to reduce material COD, alleviates aerobic burden, simultaneously the generation biogas of maximum.
Sludge gas collecting device is used for the Collection and use of whole all biogas for the treatment of processes.
The method that the utlity model has is simple, the advantage that industry is workable.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 frame diagram of the present utility model
Embodiment
As shown in Figure 1, at first changing food waste pumps into the charging equalizing tank, and feeding temperature, pH etc. is regulated, and pumps into the one-level anaerobic fermentation tank after mixing.Through after one grade fermemtation, material enters the B grade anaerobic fermentation tank and continues fermentation.Water outlet after second order fermentation enters comprehensive pool, realize mud, moisture from, mud is got back to the charging equalizing tank and is again pumped into together the one-level anaerobic fermentation tank with charging, water outlet pumps into biogas-lift reinforced reactor and continues fermentation.Water outlet afterwards flows into Aerobic Pond, processes rear tube discharging up to standard.After the biogas that produces in each anaerobic fermentation tank overflows from the top, enter sludge gas collecting device, use safely after processed.Fermentor tank needs regular deslagging, the natural pond slag of discharge through dehydration after, as fertilizer field also.
All be furnished with liquidometer, thermometer, mechanical stirring, biogas stirring etc. in each anaerobic fermentation tank, be used for the Real-Time Monitoring to fermentation system in tank, tank deck is equipped with positive-pressure protecting device, guarantees safety.
Each anaerobically fermenting pot bottom is provided with water distributor, and charging is evenly distributed, and is provided with simultaneously the compressed biogas pipeline and is used for passing into compressed biogas, realizes that in fermentor tank, material fully mixes.
Being used for boiler after the biogas process dehydration of collecting in each fermentor tank, voltage stabilizing uses.
