Problems solved by technology

[0002] In the face of the pollution caused by agricultural production, biogas digesters have been built in many places to solve the pollution of organic matter. However, the biogas residue and biogas slurry discharged by large and medium-sized biogas projects have caused secondary pollution due to ineffective utilization.
Some projects treat the biogas slurry again and discharge it up to the standard. Although this avoids secondary pollution, it causes a lot of waste of resources
Usually, biogas slurry can be directly applied to farmland as a fertilizer. Although this can achieve good results, it is easily affected by the seasonality of crop planting and transportation is troublesome. No one wants to do this
Therefore, many biogas residues and biogas slurry sewage that have not been further t

Embodiment 1

[0014] a. Preparation of biogas slurry and straw mixture. Mix biogas slurry and straw powder at a ratio of 1:0.46, 10 tons of biogas slurry requires 4.6 tons of straw powder, and mix for 5 minutes to make a mixture of biogas slurry and straw with a water content of 70%.

[0015] b. Moisture regulation of cow dung. Preliminary dehydration of fresh cow dung by using solar energy in the pre-set site, generally 7-10 days in high temperature season, adding straw powder or chaff in low temperature season for water regulation, or fermenting and dehydrating in step c Part of the material is returned to adjust the moisture content of the fresh cow dung to below 70%. Before the fresh cow dung is dehydrated by solar energy, it should be sprayed with microbial agents to achieve the effect of deodorizing, inhibiting flies and killing maggots.

[0016] c. Fermentation. The fermentation stage is divided into primary fermentation and secondary fermentation:

[0017] One ferment. Mix the p...

Embodiment 2

[0021] a. Preparation of biogas slurry and straw mixture. Mix biogas slurry and straw powder at a ratio of 1:0.56, 10 tons of biogas slurry requires 5.6 tons of straw powder, and mix for 6 minutes to make a mixture of biogas slurry and straw with a water content of 60%.

[0022] b. Moisture regulation of cow dung. Preliminary dehydration of fresh cow dung by using solar energy in the pre-set site, generally 7-10 days in high temperature season, adding straw powder or chaff in low temperature season for water regulation, or fermenting and dehydrating in step c Part of the material is returned to adjust the moisture content of the fresh cow dung to below 70%. Before the fresh cow dung is dehydrated by solar energy, it should be sprayed with microbial agents to achieve the effect of deodorizing, inhibiting flies and killing maggots.

Embodiment 3

[0028] a. Preparation of biogas slurry and hulled bran mixture. Mix the biogas slurry and hulled chaff at a ratio of 1:0.5, 10 tons of biogas slurry requires 5 tons of hulled chaff, and mix for 6 minutes to make a mixture of biogas slurry and hulled chaff with a water content of 65%.

[0029] b. Moisture regulation of cow dung. Preliminary dehydration of fresh cow dung by using solar energy in the pre-set site, generally 7-10 days in high temperature season, adding straw powder or chaff in low temperature season for water regulation, or fermenting and dehydrating in step c Part of the material is returned to adjust the moisture content of the fresh cow dung to below 70%. Before the fresh cow dung is dehydrated by solar energy, it should be sprayed with microbial agents to achieve the effect of deodorizing, inhibiting flies and killing maggots.

Abstract

The invention relates to a method for preparing straw dairy manure organic fertilizer, comprising the steps of mixing a certain amount of straw powder or rice chaff, and the like, with swamp liquid; preparing into swamp liquid straw mixture with proper water content; evenly mixing the prepared swamp liquid straw mixture, the dairy manure with proper water content and zymogeneous bacteria agent; sequentially firstly fermenting, periodically piling, secondly fermenting, periodically piling, dehydrating, and stopping fermenting; and processing, packing or finish machining to prepare the organic fertilizer. The method harmlessly processes the swamp liquid and prepares the organic fertilizer therewith, not only solves the river pollution problem caused by randomly discharging the swamp liquid, but also can use the organic fertilizer for crops.

Description

technical field [0001] The invention relates to a method for processing straw cow dung organic fertilizer. Background technique [0002] In the face of the pollution caused by agricultural production, biogas digesters have been built in many places to solve the pollution of organic matter. However, the biogas residues and liquids discharged by large and medium-sized biogas projects have caused secondary pollution because they have not been effectively utilized. Some projects treat the biogas slurry again and discharge it up to the standard. Although this avoids secondary pollution, it causes a lot of waste of resources. Usually, biogas residue and slurry can be directly applied to farmland as fertilizer. Although this can achieve good results, it is easily affected by the seasonality of crop planting and transportation is troublesome. No one wants to do this. Therefore, many biogas residues and biogas slurry sewage that have not been further treated and greatly exceeded the...
