Environment-friendly kitchen waste disposer and waste disposal method

Abstract

The invention relates to an environment-friendly kitchen waste disposer and a waste disposal method by using the waste disposer. The environment-friendly kitchen waste disposer is embedded underground and comprises a waste accommodating layer, a water system heating layer, a heat complementing layer and a heat insulating layer, wherein a smashing device for smashing wastes and biodegradation complex bacteria and/or biodegradation enzymes for degrading the wastes are arranged in the waste accommodating layer; and smashed and degraded fluid is discharged into a septic tank or a blowdown pipe through a drainage outlet. The waste disposal method comprises the following steps: (1) placing the environment-friendly kitchen waste disposer underground; (2) smashing the kitchen wastes by using the smashing device; and (3) fermenting the biodegradation complex bacteria and/or biodegradation enzymes and the wastes for degradation; and 4, discharging or recycling part of or all of fermented humus to the septic tank. The environment-friendly kitchen waste disposer does not occupy area, does not exhaust odor to the atmosphere, and is free of noises and low in energy consumption and suitable for places, such as canteens, communities, hotels, dining mechanisms and the like where the kitchen wastes are centralized.

Description

technical field [0001] The invention relates to a treatment method for garbage, in particular to an environment-friendly treatment method for kitchen garbage. Background technique [0002] Food waste refers to food residues and processing waste generated in food processing, catering services, and unit catering activities. The amount of food waste in my country is very large, and it is showing a rapid upward trend. General large cities produce more than 3,000 tons of domestic waste every day, of which kitchen waste accounts for about 50%. How to efficiently and quickly dispose of kitchen waste has always been a common concern of the government and society. [0003] The hazards of food waste mainly include the following aspects: [0004] 1. Affect the urban appearance and living environment. In terms of sensory properties, food waste is greasy and wet, which affects people's visual and olfactory comfort and living hygiene. The high moisture content and organic components ...

[0006] 3. Hazards caused by waste edible oils and fats

Due to the characteristics of high oil, high salinity, and high nutritional content of food waste in my country, and the complex components contained in it, there are two problems in the anaerobic fermentation of biogas: one is that the food waste has more nutrients, and the hydrolysis acidification stage produces There are more acids, which is not conducive to the subsequent biogas production by methanogenic bacteria; second, the carbon-nitrogen ratio of food waste in my country is uncoordinated, the nitrogen content is high, and there are many impurity inhibitors, which are not conducive to the adoption of anaerobic biogas production technology.

However, the biochemical processor dissipates heat quickly in the atmosphere. During the fermentation process, processes such as deodorization, sewage discharge, and evaporation are required. The processing cycle is long, the energy consumption is large, and additional bacteria are required for each treatment. The cost is high and the land area is large.
