Waste resource recycling equipment for southern Anhui spotted pig breeding

Abstract

The invention relates to the technical field of southern Anhui spotted pig breeding, and discloses waste resource recycling equipment for southern Anhui spotted pig breeding. A method comprises the following steps that firstly, a pig house is bred in the mode that padding is laid on the ground; the used padding is mixed with straw collected near a pig house or in a farmland of the pig house and other organic materials through mixing equipment for high-temperature aerobic composting; step 2, performing post-fermentation on the material subjected to high-temperature aerobic composting, recycling one part of the material as padding, and selling the other part of the material as organic fertilizer or applying the other part of the material to a hog house own farmland; thirdly, corn straw silage generated in the farmland serves as pig feed, crop straw and used padding are mixed, and high-temperature aerobic composting in the first step is carried out; and 4, removing large-particle impurities from the excrement generated by the hog house through a grating, and then carrying out solid-liquid separation treatment. Segmented and staged treatment is carried out, useful resources in the feces are recycled as far as possible, the treated sewage meets the farmland irrigation requirement, the investment is small, the operation cost is low, and the process is simple.

Description

technical field [0001] The invention relates to the technical field of breeding of southern Anhui pigs, in particular to a waste recycling and utilization equipment for breeding of southern Anhui pigs. Background technique [0002] At present, the waste treatment of large-scale farms is facing great environmental protection pressure. The traditional treatment method is usually direct return to the field. Although this method is simple to operate and low in cost, it has serious pollution; anaerobic fermentation is used for pigs. The method of recycling the waste from the house, anaerobic fermentation of pig manure to produce biogas, the biogas power generation is used for lighting, housing or other purposes, and the biogas slurry is discharged into the nearby fish pond or used for irrigation, and the biogas residue is returned to the field. The method greatly improves the recycling efficiency of pig house waste and reduces the production cost. However, in the actual operation...

Problems solved by technology

[0002] At present, the waste treatment of large-scale farms is facing great environmental protection pressure. The traditional treatment method is usually to return directly to the field. Although this method is simple to operate and low in cost, it pollutes seriously; through anaerobic fermentation The method of recycling the waste from the house, the pig manure is anaerobically fermented to produce biogas, the biogas is used for lighting, housing or other purposes, and the biogas slurry is discharged into the nearby fish pond or used for irrigation, and the biogas residue is returned to the field. This method greatly improves the recycling efficiency of pig house waste and reduces production costs. However, in the actual operation process of this method, the collection of pig house waste is still a big problem. The current method is usually manual Cleaning, which leads to increased labor costs, heavy workload, and poor working environment
