Problems solved by technology

The analysis results show that the organic matter content of fully degraded food waste degradation products is as high as 76.3%, and contains more than 3.21% of nitrogen, phosphorus and potassium nutrients, but the seed germination index of its extract is low, so it can be used directly as an organic fertilizer There may still be certain risks

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

[0040] 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

[0042] 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 method for combined composting of kitchen degraded products. The method comprises the following steps: mixing fermentation raw materials including kitchen degraded products, traditional Chinese medicine dregs and sludge to obtain a mixture, and performing aerobic fermentation on the mixture, After the fermentation product is cooled to normal temperature, it is discharged and air-dried to obtain organic fertilizer. The present invention uses the degraded food waste as raw material, combined with traditional Chinese medicine slag and sludge for aerobic fermentation. The treatment is more convenient, and the peculiar smell is lower during the treatment process, and the amount of kitchen waste consumed is larger; on the other hand, the present invention can effectively solve the environmental problems caused by traditional Chinese medicine residue and sludge at the same time, and is more environmentally friendly; Composting by the inventive method has the characteristics of safety and high efficiency, and the heavy metal content of the prepared fertilizer meets the standards of the Ministry of Agriculture for organic fertilizers, is rich in nutrition, and has good seed germination.

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. ...
