Environmental-protection energy-efficient livestock and poultry night soil and organic waste rapid activation fermentation method

Abstract

The invention relates to an environmental-protection energy-efficient livestock and poultry night soil and organic waste rapid activation fermentation method, which belongs to the technical field of microbe aerobic fermentation. The method is characterized in that while stirring, direct current with certain intensity is energized to livestock and poultry night soil and organic waste, the anaerobic bacteria can be rapidly activated and rapidly grown, the aerobic fermentation shortens the starting time. Without addition of the fiber materials, aerobic fermentation can be carried out on the pure chicken manure, pig dung, cattle dung or organic waste; content of the nutrition of an organic fertilizer is high, the method has the advantages of high electric energy utilization and little heat waste, the moisture can be reduced by 3-5% in one hour, no three-waste is discharged according to the method, the method has deodorization effect, the processed ferment materials are piled to strip stacks, and can generate heat according to stain in 12 hours to the temperature of more than 65 DEG C. The organic fertilizer through aerobic fermentation increases the quality, and environmental pollution is reduced. The method is excellent for all-sized farms or sewage treatment stations.

Description

technical field [0001] The described quick activated fermentation method for livestock and poultry manure and waste is a processing method for pollutants that affect the environment: livestock and poultry manure, food factory and urban sludge reuse. Background technique: [0002] It has always been a headache to deal with livestock manure and sludge in food factories of large and medium-sized farms. The processing method of most plants is aerobic fermentation to make organic fertilizer or resell to organic fertilizer factory. The moisture content of the aerobic fermentation material must be below 65%. During the aerobic fermentation process, a large amount of auxiliary materials must be added, such as rice husk powder, straw powder, peanut shell powder, etc. The substance can be fermented in a short time only by water absorption and increasing the carbon-nitrogen ratio. The auxiliary materials such as rice husk powder that need to be added are seasonal and not available e...
