Problems solved by technology

[0002] In recent years, bio-organic fertilizers have been widely used due to their functions of improving soil quality. At present, the main raw materials for the production of bio-organic fertilizers are various crop straws and livestock and poultry manure. Among crop straws, most crops such as corn and wheat Straw can be made into good feed. If it is made into fertilizer, the economic value is relatively low. Tobacco waste such as fresh tobacco leaves, low-quality dry tobacco leaves and tobacco stalks produced in the process of tobacco planting and processing is more special. On the one hand, it is not suitable for For processing feed, on the other hand, if it is directly returned to the field, it is easy to infect tobacco field diseases such as mosaic disease. Therefore, tobacco waste is usually burned in the field or piled up in the field. A big problem for post-tobacco farmers

Embodiment 1

[0022] The present embodiment utilizes the technology of tobacco waste production biogas and bio-organic fertilizer, comprises the following steps:

[0023] a. Pre-shredding: use a shredder to shred the tobacco waste into 20mm blocks or strips;

[0024] B, mixing auxiliary material: take the tobacco waste after 1000kg crushing, add 500kg excrement and 3kg microbial inoculum, described microbial inoculum comprises 50% Bacillus subtilis and 50% Bacillus licheniformis, stir after mixing;

[0025] c. Anaerobic fermentation: Put the mixed materials into a closed fermentation tank for anaerobic fermentation to obtain biogas, which is used for combustion, lighting or power generation;

[0026] d. Solid-liquid separation: solid-liquid separation of biogas residue and biogas slurry after biogas production;

[0027] e. Secondary ingredients: Weigh 1000kg of biogas residue, add 200kg of biogas slurry and 2kg of microbial inoculum, said microbial inoculum includes 70% of Bacillus subtil...

Abstract

The invention discloses a process for producing marsh gas and bioorganic fertilizer by utilizing tobacco waste. The process comprises the following steps of: a, primary crushing; b, auxiliary material blending; c, anaerobic fermentation; d, solid-solution separation; e, secondary feed proportioning; f, stacking and fermentation; g, magnetic concentration; h, drying; i, pulverization; and j, packaging. According to the process, through carrying out the anaerobic fermentation and aerobic fermentation after a microbial agent is added into the tobacco waste, the marsh gas which is higher in value and the high-quality bioorganic fertilizer are produced; the recycle of resources is realized; the waste is changed into the valuable; the difficult problem of the tobacco waste, which puzzles a tobacco grower for a long term, is really solved; and the process is better in economic benefit and social benefit.
