Problems solved by technology

At present, there are mainly several ways for the resource utilization of kitchen waste oil. One is to use kitchen waste oil to extract stearic acid and oleic acid through industry and apply it to daily necessities, medicine, building materials, etc.; the other is to use kitchen waste oil To produce biodiesel, the third is to use kitchen waste oil to produce lubricating oil, etc. However, due to the complicated secondary processing technology and high cost of kitchen waste oil, although it has achieved certain application effects in actual production, it has not really been used efficiently. It seems that there are still quite a lot of waste kitchen oils that enter the human body again after being processed.

Embodiment 1

[0024] A method for composting kitchen waste oil, comprising the following steps:

[0025] (1) Sawdust and cow dung are pulverized;

[0026] (2) adding the sawdust and cow dung obtained in step (1) to kitchen waste oil for mixing, and mixing evenly to form a product to be fermented;

[0027] (3) Add 0.5wt% solid strains to the product to be fermented obtained in step (2), adjust the water content of the product to be fermented to 55%, and adjust the C / N ratio of the product to be fermented to 28:1, and then stacked into strips for aerobic fermentation, and fermented for 14 days to obtain decomposed kitchen waste oil compost.

Embodiment 2

[0029] A method for composting kitchen waste oil, comprising the following steps:

[0030] (1) sawdust and cow dung are pulverized, the particle diameter of sawdust after pulverization is 5mm, and the particle diameter of cow dung is 6mm;

[0031] (2) Add the sawdust and cow dung obtained in step (1) to the kitchen waste oil for mixing, and mix the sawdust, cow dung and kitchen waste oil in a ratio of 14:8:1 by volume, and mix evenly. to form a product to be fermented;

[0032] (3) Add 0.4wt% solid strains to the fermented product obtained in step (2), adjust the water content of the fermented product to 50%, adjust the C / N ratio of the fermented product to 30:1, adjust the When describing the C / N of the fermented product, use the amount of sawdust to increase the C content, or use the method of adding urea to increase the N content, and then pile up into a stack of 1.4 meters high and 1.5 meters wide. Oxygen fermentation, turn over once every 5 days, aerobic fermentation fo...

Embodiment 3

[0034] A method for composting kitchen waste oil, comprising the following steps:

[0035] (1) sawdust and cow dung are pulverized, the particle diameter of sawdust after pulverization is 12mm, and the particle diameter of cow dung is 10mm;

[0036] (2) Add the sawdust and cow dung obtained in step (1) to the kitchen waste oil for mixing, and mix the sawdust, cow dung and kitchen waste oil in a ratio of 11:7:1 by volume, and mix evenly. to form a product to be fermented;

[0037] (3) Add 0.6wt% solid strains to the product to be fermented obtained in step (2), adjust the water content of the product to be fermented to 60%, adjust the C / N ratio of the product to be fermented to 25:1, adjust the When describing the C / N of the fermented product, use the amount of sawdust to increase the C content, or use the method of adding urea to increase the N content, and then pile it up into a stack with a height of 1.0 meters and a width of 2.5 meters.

Abstract

The present invention relates to a kitchen waste oil composting method and a production process thereof, and the kitchen waste oil composting method comprises the following steps: smashing sawdust andcow dung; adding the sawdust and cow dung into kitchen waste oil for mixing evenly to obtain a to-be-fermented matter; adding a solid strain into the to-be-fermented matter, adjusting water content and C / N ratio, and piling into a strip stack pile for aerobic fermentation to obtain a decomposed kitchen waste oil compost. The beneficial effects are as follows: the kitchen waste oil composting method uses the kitchen waste oil for composting, the sawdust and the cow dung are added, composting time is shortened, the reuse of waste is realized, environmental pollution is reduced, people's healthis ensured, and the method is of great significance for development of circular economy.

Description

technical field [0001] The invention relates to a composting method, in particular to a composting method of kitchen waste oil. Background technique [0002] Composting refers to a kind of dark brown, loose texture and earthy smell product obtained by fermenting degradable organic matter in waste through the action of microorganisms under certain conditions and decomposing. Composting is generally divided into two types: aerobic composting and anaerobic composting. Aerobic composting is to degrade organic matter with the help of aerobic microbial life activities under the condition of good ventilation and sufficient oxygen. Aerobic composting has high composting temperature, also known as high-temperature composting. . [0003] my country has a glorious history in the application of composting technology, but due to the late start of research on modern composting technology, China's composting technology and technology still lag behind many developed countries such as Europ...
