Problems solved by technology

Although returning to the field is an effective way to reduce the amount of biogas slurry, due to the complex composition of the biogas slurry, the use of returning to the field is also affected by many factors such as land carrying capacity and seasonal changes, resulting in that the biogas slurry cannot be fully absorbed. Further harmless treatment
[0004] Livestock and poultry manure will pollute the soil, environment, and air. The following problems will exist in the treatment of livestock and poultry manure: ①Livestock and poultry manure contains a large number of bacteria, fungi, sporophytes, and some of them also contain viruses and parasites, which are harmful to livestock and poultry. If the treat

Abstract

The invention belongs to the technical field of comprehensive utilization of biomass and livestock and poultry manure, and particularly relates to a poly-generation method employing coupling of biomass with livestock and poultry manure. The poly-generation method comprises the following steps: burning straws to generate power so as to provide heat, pretreating the straws and the livestock and poultry manure, respectively hydrolyzing and acidifying the straws and livestock and poultry manure, feeding the straws and livestock and poultry manure having been hydrolyzed and acidified into a CSTR anaerobic fermentation tank, allowing the hydrolyzed and acidified straw and livestock and poultry manure to undergo medium-temperature anaerobic fermentation in the CSTR anaerobic fermentation tank so as to obtain biogas and biogas slurry, subjecting the biogas slurry to solid-liquid separation before preparation of an organic fertilizer from the biogas slurry, and subjecting the biogas to drying, gas-water separation, desulfurization and filtration before preparation of natural gas from the biogas. According to the invention, the straw and the livestock and poultry manure are coupled and recycled to generate electricity, heat, cold, biogas and organic fertilizer, so harmless utilization of resources is realized.
