The invention provides a process for preparing livestock and poultry manure organic fertilizer by using an energy chemical technology, which comprises the following steps: s1: carrying out solid-liquid separation on the livestock and poultry manure, conveying the liquid manure to an electrolytic reactor, and conveying the solid manure to a fermentation reactor; s2: carrying out electrolytic treatment on the liquid manure; s3: detecting the water content of the solid manure, adjusting the water content of the solid manure through a spraying device, carrying out closed fermentation reaction and stirring regularly; s4: the fermented solid manure is sequentially settled to the next fermentation layer, the lifting device repeatedly conveys the solid manure to the fermentation layer, S3 is repeated until the fermentation of the lowest fermentation layer is finished, and the solid manure is discharged and made into organic fertilizer through a fertilizer making machine; s5: and collecting and treating the gas generated in the whole fermentation process by a gas collecting device to generate the biogas. In a word, the invention has the advantages of novel structure, perfect system, energy saving, environmental protection and the like. |
