Culture waste utilization method based on fermentation technology

Abstract

The invention discloses a culture waste utilization method based on a fermentation technology, belongs to the field of fermentation, and particularly relates to a culture waste utilization method based on a fermentation technology. The method comprises the following steps: fermenting culture waste to form an organic fertilizer for utilization, and in the process, adding pre-aerated particles intosolid waste after dehydration of the culture waste; during high-temperature composting, water in the hot-melt water ball is in contact with the gas dispersing powder after hot melting of the hot-meltwater ball to generate a large amount of carbon dioxide, on one hand, when the carbon dioxide does not completely overflow to the outside, the concentration of the carbon dioxide in the compost is relatively high, anaerobic bacteria can be effectively stimulated, and the activeness of the anaerobic bacteria is improved; on the other hand, after carbon dioxide completely overflows, the gas containing channel communicated with the outside is formed in the compost, and the outside air can enter the compost so that the survival requirement of aerobic bacteria on oxygen is met, the synchronous action of the aerobic bacteria and anaerobic bacteria can be realized, the time required by composting is remarkably shortened, and the efficiency of preparing the organic fertilizer from the livestock wastes is further improved.

Description

technical field [0001] The invention relates to the field of fermentation, more specifically, to a method for utilizing farming waste based on fermentation technology. Background technique [0002] The solid livestock and poultry manure, feed residues and breeding bedding produced by the solid-liquid separation of pig farm wastewater are organic solid wastes. Long-term stacking will pollute the soil, groundwater and breed a large number of germs. If the temperature is high, it will be accompanied by an unpleasant smell. Environmental damage is serious. However, this kind of organic waste has high nitrogen and phosphorus content, and it can be made into bio-organic fertilizer by using biological methods to ferment compost. Bio-organic fertilizer is an environmentally friendly fertilizer, the main source of which is animal manure and plant residues. Organic fertilizers are also known as "farm fertilizers". Those that use organic matter (compounds containing carbon) as ferti...

Problems solved by technology

[0003] Generally, livestock manure is used as organic fertilizer, and ordinary farmers generally use it directly, but livestock manure will carry some bacteria, such as coliform bacteria, nematodes and other germs and pests, etc., and it is easy to infect crops if it is not treated directly, and people eat it Infected crops pose certain safety hazards to human health, so they need to be treated, usually through composting to form orga
