Production method and device of three-phase biological bacterium organic fertilizer

Abstract

The invention relates to a production method and a device of a three-phase biological bacterium organic fertilizer, which is characterized in that biogas fermentation, an anaerobic bacteria species propagation and fermentation integration continuous and rapid fermenting device and a three-phase rapid fermentation technology are used for processing city industrial organic waste materials, crops straws and human and animal night soil in a harmlessness manner to produce the high efficiency biological bacterium organic fertilizer. According to the invention, in a first phase, the animal dung with high carbon-nitrogen ratio is used for propagation and fermentation to produce secondary liquid strain; the secondary liquid strain with high carbon-nitrogen ratio is used as a main nitrogen source for high temperature aerobic fermentation in a second phase, and a third phase anaerobic fermentation is carried out after the second phase high temperature aerobic fermentation. The characteristics of high water content, high nitrogen and low carbon of human and animal night soils are used for rapidly decomposing by employing biogas fermentation to produce a lot of humic acid, amino acid and available nitrogen, rapidly available phosphorus, and rapidly available potassium. A biogas broth is used for propagation and fermentation of biological bacterium, the biological bacterium propagation technology and production equipment are simplified, a lot of fermentation raw materials can be saved, biological bacterium propagation efficiency is accelerated, and beneficial biological bacterium survival rate can be increased.

Description

technical field [0001] The invention relates to a special equipment and process for the integration of biogas fermentation, strain expansion and fermentation, especially the use of three-stage fermentation method to transform industrial organic waste, crop straw, etc. Industrial organic waste, crop straw, and human and animal manure are mainly treated in a harmless manner for efficient resource utilization. Background technique [0002] In recent years, there have been more and more research results on the production of bio-organic fertilizers from industrial organic waste, crop stalks, and human and animal manure. For example, the Chinese Invention Patent Specification Publication No. CN1336353A provides a kind of "Full Price Nutritional Special Fertilizer" that utilizes human and animal manure, industrial Examples of bio-organic fertilizers produced from organic waste and crop stalks, its disadvantages: [0003] (1) Most of the fermentation processes used are not perfect,...

AI Technical Summary

Problems solved by technology

[0003] (1) Most of the fermentation processes used are not perfect, the strain propagation process is complex and costly, and the production cycle is long;

[0004] (2) Microorganisms cannot be effectively used to decompose cellulose and lignin to improve the utilization rate, and the ecological environment and conditions for microbial production are not considered comprehensively;

[0005] (3) There are too few beneficial bacteria in the bio-organic fertilizer produced, the fertilizer efficiency is not high, and it cannot be commercialized and applied;

[0006] (4) The fermentation temperature is low, the fermentation period is long, and the output is low, so it cannot be produced in a large-scale continuous flow operation;

[0007] (5) Sewage discharge, heavy odor, and environmental pollution
