Process for preparing livestock and poultry manure organic fertilizer by using energy chemical technology

Abstract

The invention provides a process for preparing a livestock and poultry manure organic fertilizer by using an energy chemical technology, which comprises the following steps: S1, carrying out solid-liquid separation on livestock and poultry manure, conveying liquid manure into an electrolysis reactor, and conveying solid manure into a fermentation reactor; S2, carrying out electrolytic treatment onthe liquid excrement; S3, detecting the moisture content of the solid feces, adjusting the moisture content of the solid feces through a spraying device, carrying out closed fermentation reaction, and stirring the solid feces at regular time; S4, sequentially settling the fermented solid excrement to the next fermentation layer, repeatedly conveying the solid excrement to the fermentation layer by the lifting device, repeating S3 until the fermentation of the fermentation layer at the lowermost layer is finished, and discharging a product and preparing an organic fertilizer by a fertilizer preparation machine; S5, collecting the gas generated in the whole fermentation process and treating the gas through a gas collecting device to generate biogas. In conclusion, the system has the advantages of novel structure, complete system, energy conservation, environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of manure treatment, and in particular relates to a process for preparing livestock and poultry manure organic fertilizer by using energy chemical technology. Background technique [0002] Livestock and poultry manure mainly refers to a type of rural solid waste produced in the livestock and poultry breeding industry, including pig manure, cow manure, sheep manure, chicken manure, duck manure, etc. In the early days of traditional animal husbandry production, individual farming was the mainstay. The number of individual livestock and poultry in the farm was small, and the feces and urine produced were relatively small. In the mid-1980s, on the one hand, due to the constraints of natural resources in my country, The development of animal product production can only be realized through the intensified use of resources. There is a trend towards intensification and centralization of animal husbandry production. S...

Problems solved by technology

[0003] At present, the effective treatment method for livestock and poultry manure is to prepare it into organic fertilizer for land application, but the preparation of organic fertilizer from livestock and poultry manure has cumbersome processing procedures, high energy consumption, and high cost, and the organic fertilizer prepared by ordinary processes Contains a large number of harmful germs, if applied directly to the land, it will cause land pollution and affect the growth of the work. Therefore, the present invention provides a process for preparing livestock and poultry manure organic fertilizer by using energy and chemical technology
