Embodiment Construction

[0019] 1. Adjust the humidity of rice husk, wheat bran and sawdust to 40%, and evenly spread the liquid with 30% concentration of a solution aid, which is composed of 40% urea, 35% ammonium bicarbonate and 25% starch by weight percentage . Natural composting or composting with the addition of an appropriate amount of microbial agents, concentrated within 20 days at a temperature of 25°C in summer and autumn, can be put into the next stage of fermentation.

[0020] 2. Get the above-mentioned pre-fermented organic matter and livestock and poultry manure to mix mechanically in a weight ratio of 1: 0.5, evenly spread the stabilizer powder of 2‰ of the above-mentioned material weight, and the stabilizer powder consists of 60% superphosphate and Composed of 40% fly ash, it will be formally fermented after being evenly premixed.

[0021] 3. During the formal fermentation process, when the pile is turned mechanically, the stabilizer powder equivalent to 5‰ of the fermented material i...

Abstract

The invention relates to a preparing technology of a fertilizer, especially a zymotechnique that can degrade organic offal. The disintegrant solution is added in the pre-fermenting process which improves the fermenting effects; the formula of the fermenting material is regulated, the environmental condition for microbial metabolism is improved, the stabilizer is added in the process, all the previous aspects have increased the fermenting efficiency substantially; the stabilizer is sprinkled in the turning over process for oxygen inletting and dehumidifying to prevent the evaporation of the nitrogen and increase the soluble fosforus. The invention can increase the digesting efficiency and it can increase the total nutrients (the major element of N+P2O5+K2O) of the digesting substances to more than 6%.

Description

technical field [0001] The invention relates to a fertilizer preparation process, in particular to a fermentation process for degradable organic waste. Background technique [0002] The traditional fermentation process, no matter natural compost fermentation, artificial or mechanical fermentation, uses aerobic microorganisms to convert various animal and plant wastes, one is various degradable organic wastes in agricultural production and life, such as feces and slops , straw, etc., and the second is that various degradable organic wastes in industrial production, such as papermaking black mud, sugar residue, wood chips, dregs, etc., are decomposed and converted into raw materials that can be used as agricultural fertilizers or directly as organic fertilizers. [0003] The invention with the publication number of CN 1160032 discloses a method for producing organic granular compound fertilizer with crop stalks, which includes taking the crop stalks...
