A kind of excrement and urine treating system take biogas engineering as tie
Technical field
The present invention relates to a kind of modern agriculture field, specifically a kind of excrement and urine treating system take biogas engineering as tie.
Background technology
The breeding technology, epidemic prevention technology and the food utilization efficiency that are conducive to improve the pig farm because of large scale of pig farm; level of management are also improved accordingly; disperse raising greatly to reduce production costs and boost productivity than traditional peasant household, thereby, the main developing direction of aquaculture become.Meanwhile, this batch production is concentrated and is raised live pig, also makes animal manure and rushes hurdle waste water concentrations, causes environmental pollution, and such as not science processing, be bound to serious environment pollution and water source also affect the normal production of self.
But the intractability of piggery wastewater is very large, the one, and water displacement is large, the 2nd, solid-liquid mixes, and organic concentration is high, and the 3rd, pig-breeding already is the meagre profit industry, be subject to the dual-pressure in nature and market, be difficult to bear the needed investment of general domestic sewage treatment process and operational management cost.
The utility model content
The purpose of this utility model is for current animal manure and rushes hurdle waste water and be difficult to the processing problem, a kind of excrement and urine treating system take biogas engineering as tie is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of excrement and urine treating system take biogas engineering as tie, it comprises manure pit 1, homogeneous pond 2 and anaerobic ferment devices 3, manure pit 1 is connected with homogeneous pond 2, homogeneous pond 2 is connected with anaerobic ferment devices 3, anaerobic ferment devices 3 is comprised of the compound anaerobic reactor of UBF, it is characterized in that anaerobic ferment devices 3 also is connected with settling tank 6 and methane purifying device 4, methane purifying device 4 is connected with biogas electricity generation apparatus 5.
The beneficial effects of the utility model:
(1) the utility model is saved oxygen supply equipment and power consumption, and working cost is low, and the sludge creation amount is less, and the mud that produces can also the as fertilizer sources utilization.It also has unique degradation capability to some hard-degraded substance and poisonous organism, can transform to remove the lower concentration toxic substance.
(2) the utility model uses piggery waste intermediate temperature anaerobic fermentation control technique, liquid natural pond, natural pond slag to hang down into the conveying technology principle, solves problem of environmental pollution, realizes resources circulation, regeneration.
(3) the utility model has been given full play to the Link role of biogas in production and operation, not only can produce the green organic agricultural-food with plant husbandry such as grain, vegetables, melons and fruits, can also solve problem of environmental pollution, has good economic benefit and social benefit.
Description of drawings
Fig. 1 is structure principle chart of the present utility model.
Among the figure: 1, manure pit, 2, the homogeneous pond, 3, anaerobic ferment devices, 4, methane purifying device, 5, biogas electricity generation apparatus, 6, settling tank, 7, natural pond liquid, 8, biogas.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in detail.
Such as Fig. 1.
The utility model provides a kind of excrement and urine treating system take biogas engineering as tie, it comprises manure pit 1, homogeneous pond 2 and anaerobic ferment devices 3, manure pit 1 is connected with homogeneous pond 2, homogeneous pond 2 is connected with anaerobic ferment devices 3, anaerobic ferment devices 3 is comprised of the compound anaerobic reactor of UBF, it is characterized in that anaerobic ferment devices 3 also is connected with settling tank 6 and methane purifying device 4, methane purifying device 4 is connected with biogas electricity generation apparatus 5.
The utility model system works method is as follows:
The pig manure that (1) will produce every day, urine enter manure pit 1 after collecting, and enter homogeneous pond 2 after removing inorganic foreign material, stir, and obtain mixed solution;
(2) mixed solution that step (1) is obtained is in the action of gravity oil removal matter of going down, and behind the liquefacttus, the anaerobic fermentation tank UBF anaerobically fermenting that pumps into again in the anaerobic ferment devices 3 obtains natural pond liquid 7, biogas 8 and natural pond slag;
(3) just the natural pond liquid 7 that obtains of step (2) enters settling tank 6 and carries out precipitate and separate, the biogas 8 that produces enters methane purifying device 4 and purifies, by biogas electricity generation apparatus 5 generatings, the waste heat that produces is used for heating of the compound anaerobic reactor of UBF, and the natural pond slag of generation then is directly used in the organic fertilizer of vegetables, grainfield, orchard, herbage.
Every day wash-down water, pig urine, remove the pig hair, particle foreign material and suspended solids enter manure pit 1,2 tops, homogeneous pond are provided with rotary type grid maker screening excrement slag, sewage after the slagging-off and argol enter 2 bottoms, homogeneous pond in the lump, the action of gravity oil removal matter of going down, sewage behind the liquefacttus pumps into the compound anaerobic reactor of UBF again and carries out anaerobically fermenting, the technique that adopts the compound anaerobic reactor of efficient UBF to ferment, mesophilic digestion (commonly used heating in winter), normal circumstances is taked 4h, morning and afternoon, each 2h used the proof submersible sand discharging pump charging, and natural pond liquid 7 enters settling tank 6 and carries out precipitate and separate.Settling tank 6 supernatant liquors water vegetable field, herbage, orchard sprinkling irrigation by pipe network.
Swine excrement is not as refuse and the rubbish environment that depollutes, but as intermediates, raw materials for production and resource as preciousness, by the anaerobically fermenting link, entering the Harmless that carries out anaerobically fermenting in the anaerobic ferment devices 3 processes, the result is 8 ℃ ~ 65 ℃ of temperature, pH value is in 6 ~ 8 the anaerobic environment, by a large amount of microorganisms, it mainly is zymogenic bacteria, hydrogen-producing acetogens, the oxygen consumption acetogen, food oxygen methanogen, the five large monoid bacteriums such as food acetic acid and methane producing bacterium, swine excrement in the anaerobic ferment devices 3 is decomposed, digestion, biogas is produced in reduction, natural pond slag and natural pond liquid.
Biogas is a kind of reproducible biological clean energy, its composition mainly is about 70% methane and about 30% carbonic acid gas, as geseous fuel, the calorific value that biogas is every cubic metre is about 5500 kilocalories, and every cubic metre of heat value only is 3300 kilocalories, so biogas is again a kind of new forms of energy, fresh fuel.Biogas is exported as generating through after purifying, and has solved pig farm part producing, living needs.
