Embodiment 1

[0031] The organic fertilizer production method based on the perishable garbage in the farmer's market comprises the following steps:

[0032] (1) Removal of impurities, sorting and removing impurities in the garbage that cannot be made into organic fertilizers, such as metals, stones, etc.;

[0033] (2) Press filter to dehydrate the cleaned garbage, control the pressure of filter at 0.1-0.2MPa, press filter until the water content of the filter residue is 60%, and obtain the filter residue and filtrate;

[0034] (3) mechanically crushing the filter residue to obtain filter residue fragments;

[0035] (4) Add the filter residue fragments to the filtrate to ensure that the solid content is 30%. If the filtrate is insufficient to replenish water, add additives at the same time, stir for 1 hour at a temperature of 25 degrees Celsius, and stand for 2 hours to obtain a slurry; additives Including diatomaceous earth, starch-based plastics, and garbage base materials, the weight rat...

Embodiment 2

[0039] The organic fertilizer production method based on the perishable garbage in the farmer's market comprises the following steps:

[0040] (1) Removal of impurities, sorting and removing impurities in the garbage that cannot be made into organic fertilizers, such as metals, stones, etc.;

[0041] (2) Press filter and dehydrate the cleaned garbage, control the pressure of filter at 0.2-0.3MPa, press filter until the water content of the filter residue is 65%, and obtain the filter residue and filtrate;

[0042] (3) mechanically crushing the filter residue to obtain filter residue fragments;

[0043] (4) Add the filter residue fragments to the filtrate to ensure that the solid content is at 25%. If the filtrate is not enough to replenish water, add additives at the same time, stir at 40 degrees Celsius and pass oxygen treatment for 1.5 hours, and stand for 3 hours to obtain Slurry; additives include diatomaceous earth, starch-based plastics, and garbage base materials, with...

Abstract

The invention belongs to the field of garbage treatment, and specifically relates to a perishable garbage in farm product markets based organic fertilizer production method. The method includes the following steps: (1) performing junk removing, and sorting and removing junk in garbage that cannot make organic fertilizer; (2) performing pressure filtration dehydration on the junk-removed garbage sothat filter residues and filtrate can be obtained; (3) performing mechanical crushing on the filter residues to obtain filter residue debris; (4) adding the filter residue debris into the filtrate, and simultaneously adding an auxiliary agent, performing stirring for at least 1 hour under a temperature being 25-40 DEG C, and performing standing for 2-3 hours so that slurry can be obtained; (5) adding a compound microbial agent into the slurry, and performing fermentation to obtain a fermentation broth; and (6) concentrating and drying the fermentation broth, controlling water content to be at25-30%, and performing granulation so that the organic fertilizer can be obtained. The method is complete in garbage resource utilization and nutrient composition recycling, good in fertilizer efficiency of the obtained organic fertilizer, excellent in particle formability and good in slow-release effect of active ingredients.

Description

technical field [0001] The invention belongs to the field of garbage treatment, and in particular relates to a method for producing organic fertilizer based on perishable garbage in agricultural trade markets. Background technique [0002] Garbage from farmers’ markets is one of the important sources of urban waste. More than 95% of the garbage from farmers’ markets is cabbage leaves and fruit peels, mainly organic components. At present, the treatment of farmer's market waste is mainly based on ordinary composting. The composting method is to process urban waste according to the composting process to make fertilizer. Composting technologies can be roughly divided into three categories: simple composting, aerobic composting and anaerobic composting. There is still a certain gap between my country's garbage composting technology and industrialized composting technology in developed countries, and the composting rate is not high. The main advantage of the composting method is...
