Example Embodiment

[0025] Example 1:

[0026] A method for continuously producing solid and liquid organic fertilizers from pig manure. The solid-liquid separation unit, solid fermentation unit, drying unit and liquid fermentation unit of pig manure are set up. The process is: solid-liquid separation unit → solid fermentation → drying unit → Solid products; solid-liquid separation unit solid→liquid fermentation unit→liquid product; solid-liquid separation unit, solid-state fermentation unit and drying unit are connected horizontally in series, and the feeding device continuously sends pig manure to the screw press, and the screw press treats the pig manure Continuously squeeze, the separated solid pig manure continuously enters the solid fermentation suffocation and stirs to disperse, the solid fermentation suffocation feeder continuously adds the special compound microbial inoculant for the harmless treatment of livestock and poultry manure, and the stirring driving device drives the stirring shaft...

Abstract

The invention discloses a method for continuously producing solid and liquid organic fertilizers by using livestock and poultry feces. The process of the method comprises a solid-liquid separation unit-solid fermentation-a drying unit-a solid product and a liquid fermentation unit-a liquid product. The method specially comprises the following steps of continuously entering solid livestock and poultry feces separated by delivering the livestock and poultry feces into a worm press into a fermentation chamber of a solid fermentation machine for continuous biochemical treatment, and adding thereby trace elements to obtain a solid fertilizer product; entering liquid obtained through solid-liquid separation and liquid which flows out of the solid fermentation machine into a liquid fermentation tank without being subjected to multi-stage continuous biochemical treatment through a fermentation accessory ingredient, and adding the trace element to obtain a liquid fertilizer product. The method disclosed by the invention has the advantages of reasonable process, high automation degree, short production period, 10-20 hours fermentation time, processing cost reduction and no secondary pollution, thoroughly solves the problems of pollution of feces generated due to large-scale livestock and poultry breeding on the environment and demand of crops on organic fertilizers, realizes the recycling treatment and has good economic benefit, social benefit and ecological benefit.

Description

technical field [0001] The invention belongs to the technical field of machine fertilizer processing and the technical field of circular economy, and relates to a method for producing organic fertilizer by biological fermentation, in particular to a method for continuously producing solid and liquid organic fertilizer from poultry manure. Background technique [0002] With the rapid development of the breeding industry, a large amount of livestock manure is produced. Untreated livestock manure seriously pollutes groundwater, surface water, soil, crops, etc., causing environmental pollution and endangering people's health. The development of pollution-free, green and organic agriculture, the use of microorganisms to ferment organic materials, and the industrial production of organic fertilizers have become a major trend. The rational use of livestock and poultry manure can not only change the situation of environmental pollution, but also effectively use resources to provide ...
