Small distributed kitchen garbage composting device and using method thereof

Abstract

The invention discloses a small distributed kitchen garbage composting device and a using method thereof. The small distributed kitchen garbage composting device comprises an air pump and a small fermentation bag, an air outlet port of the air pump communicates with an air inlet pipe, a cross pipe is installed on the surface of the bottom side of the small fermentation bag, the center of the crosspipe communicates with the air inlet pipe, a gas flow meter penetrates through the surface of the gas inlet pipe, a gas outlet pipe is communicated with the position, opposite to the cross pipe, of the surface of the top side of the small fermentation bag, and a collecting tank is communicated with one end of the gas outlet pipe. According to the small distributed kitchen garbage composting device and the using method thereof, a static composting system is adopted, the area occupied by composting is reduced, pathogenic bacteria and worm eggs in kitchen garbage can be effectively killed, the harmless purpose is finally achieved, the efficiency is high, the cost is low, and the environment-friendly purpose is achieved.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a small-scale distributed kitchen waste composting device and a method for using the same. Background technique [0002] Kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. The main sources are household kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. Kitchen waste contains extremely high moisture and organic matter, which is easy to perish and produces stench. Illegal collection and recycling of kitchen waste will It poses a threat to the environment and the health of residents. Kitchen waste is composed of starch, cellulose, protein, lipids and inorganic salts. It has the following characteristics: [0003...

AI Technical Summary

Problems solved by technology

[0003] (1) The moisture content is high, and the moisture content of kitchen waste is about 80%, which also brings troubles to garbage collection, transportation and treatment;

[0004] (2) It is perishable, and the organic matter content in kitchen waste is as high as 95%; it is easy to cause corruption and odor, and it is easy to breed germs, thereby causing the spread of diseases;

[0005] (3) There are many nutrients. In addition to a large amount of organic matter, kitchen waste is also rich in nitrogen, phosphorus, potassium, calcium and various trace elements. The above characteristics indicate that kitchen waste has high utilization value. However, if Failure to deal with it in time or improper treatment will cause certain harm. Therefore, kitchen waste must be properly treated or utilized to achieve the unity of social, economic and environmental benefits;

[0009] At present, composting technology has been widely used in the treatment of excess sludge, livestock and poultry waste, urban waste, kitchen waste, yard waste, etc. Traditional composting has many shortcomings, such as high requirements for waste classification and aerobic decomposition process. The odor produced in the compost will pollute the environment, and the high cost of composting or poor quality will affect the sales of composting products
