Embodiment Construction

[0022] Below in conjunction with accompanying drawing, the present invention will be further explained and illustrated:

[0023] see figure 1 , figure 2 and image 3 , an ecological cycle system for large-scale pig farm manure treatment, including a manure collection unit, a solid-liquid separation unit, an anaerobic fermentation unit, a biogas utilization unit, and a biogas slurry utilization unit;

[0024] The manure collection unit includes a liquid collection tank 2, a septic tank 3, a sedimentation tank 4 and a liquid storage tank 5. After the feces and sewage 1 discharged from the farm pass through the liquid collection tank 2, the waste liquid flows into the sedimentation tank 4 after sedimentation. Stand-by in the liquid storage tank 5, the solid manure filtered out by the liquid collection tank 2 and the solid manure deposited in the sedimentation tank 4 are transported to the septic tank 3 for use;

[0025] The solid-liquid separation unit includes a solid-liquid...

Abstract

The invention discloses a large-scale piggery dung treatment ecological circulation system which comprises a dung collection unit, a solid-liquid separation unit, an anaerobic fermentation unit, a biogas utilization unit and a biogas slurry utilization unit. The dung collection unit comprises a slurry collection tank, a dung accumulation tank, a settling tank and a slurry storage tank, the solid-liquid separation unit comprises a solid-liquid separator and an organic fertilizer treatment device, the anaerobic fermentation unit is a multistage anaerobic reaction device and comprises a primary anaerobic reaction tank and a secondary anaerobic reaction tank, the biogas utilization unit comprises a biogas cabinet, a biogas purification device and a biogas power generation device, the biogas slurry utilization unit comprises a biogas slurry storage tank, a forestry irrigation device and a farmland irrigation device, and high-temperature oxidation resistant plastic soft protection layers are arranged above the dung accumulation tank and the slurry storage tank. Dung water is fermented to generate biogas and biogas slurry, organic fertilizers are generated after solid-liquid separation, the possibility of secondary pollution caused by waste gas is avoided, waste is effectively and sufficiently reused, and comprehensive utilization rate is increased.

Description

Technical field: [0001] The invention relates to a manure utilization system, in particular to an ecological cycle system for large-scale pig farm manure treatment. By adopting solid-liquid separation and anaerobic fermentation technology, manure and sewage are firstly separated into dry manure and manure, The dried manure is processed into organic fertilizer, and the manure is anaerobically fermented to produce biogas and biogas slurry. The biogas can be used to generate electricity, and the biogas slurry can be used to irrigate farmland and trees. Background technique: [0002] With the development of animal husbandry and the rapid increase of large-scale pig farms and pig breeding areas, the main problem is the treatment of a large amount of fecal sewage and wastewater. If the treatment is not good, it will cause environmental pollution, and in severe cases it will cause disaster. And the farmland near the pig farm, affecting the lives of farmers. If there is a way to ef...
