Embodiment 1

[0016] Add 100kg of fresh cow dung with a moisture content of 81% and 100g of compound aerobic fermentation bacteria to a 0.6m 3 In the horizontal mixer, the mixer shell and the central shaft are insulated; the shell is connected to the positive pole, the central shaft is connected to the negative pole, and a 6.5KVA direct current is connected to it while stirring; after 1 hour and 15 minutes, the temperature of the material is raised from the original 32°C to 71°C, at this time, the material is forced to blow for 30 minutes, and the material drops from 71°C to 32°C. Stop blowing and continue heating, and blow blowing when heated to 71°C again. After reciprocating four times, the power was cut off to take a sample to measure the moisture content of the material, and the moisture content at this time was 61%. Released from the mixer and piled on the cement floor, the measured temperature was 32°C. After stacking for 12 hours, the thermometer showed that the middle and upper l...

Embodiment 2

[0018] Add 100kg of fresh chicken manure with a moisture content of 74% and 100g of aerobic fermentation bacteria to a 0.6m 3 In the horizontal mixer, the shell of the mixer is insulated from the central shaft; the shell is connected to the positive pole, the central shaft is connected to the negative pole, and a direct current of 6KVA is connected to it, stirring at the same time; after 1 hour and 15 minutes, the material is heated from the original 32°C to 70°C, At this time, the material is forced to blow, blowing for 30 minutes, and the material is lowered from 70°C to 32°C. Stop blowing and continue heating, and blow when heated to 70°C again. After reciprocating three times, the power was cut off to take samples to measure the moisture content of the material, and the moisture content at this time was 60.4%. Released from the mixer and piled on the cement floor, the measured temperature was 32°C. After stacking for 10 hours, the thermometer showed that the middle and up...

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...
