The microbial heterotopic fermentation bed is a device which is characterized in that a fecal sewage fermentation bed is arranged on one side of a livestock and poultry breeding area, and the fecal sewage is not fermented in the breeding area, and comprises a fermentation tank 15 and a sewage collecting tank 16 arranged on one side of the fermentation tank 15, a reciprocating material scattering spray pipe (shielded by a cross beam 17 in the drawing and not shown) and a cross beam 17 are arranged above the fermentation tank 15, a rake overturning machine 18 capable of reciprocating on the cross beam 17 is arranged at the bottom of the cross beam 17, a sewage pump 19 is arranged in the sewage collecting tank 16, and the discharge end of the sewage pump 19 is connected to the material scattering spray pipe. The working process comprises the steps of draining the excrement to the sewage collecting tank 16 through a pipeline, starting a sewage pump 19 in the sewage collecting tank 16 at regular time or at intervals, uniformly splashing the excrement to padding of the fermentation tank 15 through a material sprinkling spray pipe, fermenting or degrading the excrement in the fermentation tank 15 by aerobic microorganisms to degrade and digest excrement and urine, realizing zero pollution emission and obtaining the bio-organic fertilizer. In the fermentation process, the beam 17 reciprocates above the fermentation tank 15, and the rake-turning machine 18 positioned on the beam 17 also reciprocates on the beam 17, so that the manure is turned and mixed, the manure and fermentation microorganisms are fully contacted with oxygen, the fermentation efficiency is improved, and the fermentation rate is increased.
In this embodiment, the fermentation tank 15 and the dirt collecting tank 16 are both arranged in the fermentation shed, the material scattering spray pipe sprays the odor once every day and stirs the odor once at regular time, the odor generated by the microorganism heterotopic fermentation bed mainly has the odor generated by the evaporation of the moisture in the excrement in the fermentation tank 15 and carrying a small amount of odor, the odor generated in the dirt collecting tank 16 and a large amount of odor generated when the material scattering spray pipe sprays the excrement into the fermentation tank 15; through setting up the fermentation canopy. The odor can be enclosed in the fermentation shed, so that the odor generated in the fermentation tank 15, the sewage collecting tank 16 and the spraying process is prevented from diffusing outwards. The door opening 3 is convenient for a conveyer to enter the fermentation shed to convey and transfer fermented excrement and padding; the ceiling 1 of the fermentation shed is made of transparent materials, and the manure in the fermentation tank 15 can be irradiated by sunlight through the transparent ceiling 1, so that the evaporation of water in the manure is accelerated; every through-hole 5 is located the high position that is close to microorganism heterotopic fermentation bed top edge, and the height of the through-hole 5 of connecting pressure manifold 6 promptly is equivalent with fermentation tank 15's top height, has avoided through-hole 5 position to set up when too high, and the fresh air that gets into in the fermentation canopy directly gets into pressure manifold 6 through-hole 5 and is taken out the problem of fermentation canopy.
In the working process of the fan 7, external fresh air enters the fermentation shed from the door opening 3 and the air inlet pipe 4 at the top of the ceiling 1, so that the air in the fermentation shed is actively ventilated, and the aerobic fermentation of the livestock and poultry manure is met; meanwhile, the fan 7 pumps out odor in the fermentation shed, so that the centralized treatment is facilitated, and the pollution to the surrounding air is reduced. Meanwhile, the air pressure in the fermentation shed is lower than the air pressure at the periphery and the top of the fermentation shed when the fan 7 is started, so that the odor in the fermentation shed can be prevented from overflowing through the door opening 3 and the air inlet pipe 4.
The central axis of the air inlet pipe 4 is vertical to the heterotopic microorganism fermentation bed, and the air outlet of the air inlet pipe 4 is positioned right above the heterotopic microorganism fermentation bed. In the air exhaust process of the fan 7, fresh air entering the fermentation shed from the air inlet pipe is blown vertically to the microorganism heterotopic fermentation tank 15, then is diffused on the surface of the fermentation tank 15 and is pumped out from the through hole 5 of the side wall 2, so that the active mixing probability of excrement and air can be further increased, and the oxygen content in the fermentation process is ensured.
The device also comprises an odor cleaning tank 8 arranged on one side of the fermentation shed, an exhaust pipe 9 is arranged at the top of the odor cleaning tank 8, and an exhaust pipe 10 of the fan 7 extends into the lower part of the liquid level of the odor cleaning tank 8. The main components of the odor of the feces generated in the livestock and poultry breeding process are ammonia gas, carbon dioxide, methane or hydrogen sulfide and the like, different waste gas cleaning solutions are added into the cleaning tank, and the odor pumped by the fan 7 is introduced into the odor cleaning tank 8, so that the absorption and purification of the odor of the feces can be realized; if hydrochloric acid with low concentration is added into the odor cleaning tank 8, ammonia gas can be introduced into the hydrochloric acid with low concentration for adsorption; for example, hydrogen sulfide can be adsorbed by caustic soda solution; or the hypochlorous acid solution is directly adopted, so that the ammonia gas and the hydrogen sulfide gas can be simultaneously treated; the methane can be recycled for the second time, and the carbon dioxide belongs to harmless gas and does not need special treatment; the treated odor can be directly discharged to the outside through the exhaust pipe 9. Therefore, the odor cleaning tank 8 can realize the treatment of various feces and odors, and avoids the problem that the atmosphere is polluted by the existing open-type emission of odors. The odor cleaning tanks 8 can be respectively built at two sides adjacent to the door opening 3, and the exhaust pipes 10 of the two fans 7 can be uniformly connected into one odor cleaning tank 8.
The side wall 2 is provided with a ventilation opening 11 at a position close to the ceiling 1, and the ventilation opening 11 is provided with an adjustable grille 12 capable of adjusting the wind direction of the inlet wind. The arrangement of the vent 11 and the adjustable grating 12 can ensure that fresh air outside the fermentation shed is blown into the fermentation shed from the side wall 2, and the angle of the adjustable grating 12 is adjusted to ensure that the air in the vent 11 is vertical to the fermentation tank 15, so that fresh air enters each part in the fermentation tank 15, and the contact area between excrement or aerobic microorganisms and oxygen is further increased.
