Embodiment 1

[0036] An embodiment of the combined composting method of kitchen degradants in the present invention comprises the following steps: the traditional Chinese medicine dregs are pulverized, squeezed and pulverized to make the water content between 15% and 80%; the sludge is air-dried to make it contain The amount of water is less than 80%; 10kg of food degradation products, 10kg of traditional Chinese medicine residue and 30kg of sludge are mixed to obtain a mixture, and the mixture is subjected to aerobic fermentation for 35 days by using a composting reactor (VTD-100, 100L), and the fermentation temperature is 49 ℃~75℃, water content is 55~65%, oxygen content is above 10mg / L·min, the fermentation product is cooled to normal temperature, and then the material is air-dried to obtain organic fertilizer. The basic physical and chemical properties of the raw materials are shown in Table 1.

Embodiment 2

[0041] An embodiment of a combined composting method of food degradation products according to the present invention. The difference between this embodiment and Embodiment 1 is that the fermentation raw material also adds a microbial agent whose mass percentage is 1% of the original fermentation raw material (purchased from Guangdong Academy of Agricultural Sciences, trade name VT).

Embodiment 3

[0043] An embodiment of a combined composting method of food degradation products according to the present invention. The difference between this embodiment and Embodiment 1 is that the fermentation raw material also adds a microbial agent whose mass percentage is 2% of the original fermentation raw material (purchased from Guangdong Academy of Agricultural Sciences, trade name decomposing agent).

Abstract

The invention discloses a kitchen degradation product combined composting method, which comprises the following steps: mixing fermentation raw materials including kitchen degradation products, traditional Chinese medicine residues and sludge to obtain a mixture, performing aerobic fermentation on the mixture, cooling a fermentation product to the normal temperature, discharging, and air-drying toobtain an organic fertilizer. The kitchen waste degradation product is used as a raw material and is combined with the traditional Chinese medicine residues and the sludge for aerobic fermentation, onone hand, the used raw material is the kitchen waste degradation product, compared with direct utilization of the kitchen waste for aerobic fermentation, the treatment is more convenient, the peculiar smell in the treatment process is lower, and the consumed kitchen waste amount is larger; on the other hand, environmental problems caused by traditional Chinese medicine residues and sludge can beeffectively solved at the same time, and the method is more environmentally friendly. The method for composting has the characteristics of safety and high efficiency, the heavy metal content of the prepared fertilizer conforms to the organic fertilizer standard of the Ministry of Agricultural Industry, the fertilizer is rich in nutrition, and the germination condition of seeds is good.

Description

technical field [0001] The invention belongs to the field of kitchen waste recycling and relates to a combined composting method of kitchen degradation products. Background technique [0002] A large amount of organic domestic waste is produced in life, and kitchen waste, as the main component of organic domestic waste, produces a huge amount, and has high water content, is perishable and smelly, easy to biodegrade, and rots and deteriorates quickly. Statistics show that Chinese cities generate no less than 60 million tons of food waste every year. If these food wastes are not dealt with in a timely and effective manner, it will cause serious harm to environmental sanitation and physical health. [0003] Kitchen waste, commonly known as swill, also known as swill, swill, etc., is mainly produced in the catering industry, canteens and households. It mainly refers to the highly perishable domestic waste produced by people's eating behavior. , High content of inorganic salts. ...
