N2N regional ecological circular agricultural system based on biogas technology

Abstract

The invention discloses an N2N regional ecological circular agricultural system based on the biogas technology, and belongs to the field of ecological circular agriculture, the N2N regional ecological circular agricultural system based on the biogas technology comprises two centers, one platform, three systems and five industries, the two centers are centered on agricultural waste harmless treatment and organic fertilizer production, the one platform is an intelligent agricultural platform based on the Internet of Things, the three systems are a waste collection, storage and transportation system, a field consumption system (organic fertilizer distribution system) and a commerce and trade logistics system, and the five industries are ecological breeding, ecological planting, energy environmental protection, agricultural product processing and ecological leisure agriculture. Compared with the prior art, the scheme provided by the invention adopts three regional circulations, the rural energy structure is optimized and improved, and the self-separation of biogas, biogas slurry and biogas residues in the biogas fermentation process is realized by designing an ingenious structure, so that the manpower and material resource cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of ecological cycle agriculture, and in particular relates to an N2N regional ecological cycle agricultural system based on biogas technology. Background technique [0002] Since the late 1990s, using household biogas as a link, the southern "pig-biogas-fruit" ecological agricultural model has been practiced, and has achieved very remarkable results. It has been identified as one of the three major ecological agricultural models to be promoted; However, with the great changes in agricultural production and rural life, the development of ecological agriculture based on biogas technology is also facing some problems: First, the biogas fermentation process is unreasonable. The wet fermentation process is adopted, and the material concentration is low, only about 1-4%. operation; structural defects of the fermentation device, low gas production efficiency, and high energy consumption for fermentation; second, th...
