Emergency treatment method for kitchen waste

Abstract

The invention discloses an emergency treatment method for kitchen waste, which comprises the following steps of: accommodating the collected kitchen waste by using a receiving bucket, and dividing into two paths by using a first conveyor; sequentially conveying one path of solid materials to a sorting machine, a presser and a second conveyor to reach a container, and conveying to a landfill site for landfill; and collecting the other path of liquid materials by using a receiving groove, sequentially conveying to a first heater for heating through a sedimentation tank and an original basin, and conveying into a three-phase horizontal centrifuge, conveying the separated light liquid to an oil-separating basin, heating by using a second heater, and conveying to a vertical centrifuge for oil-water separation, conveying waste water to a waste water basin, and conveying oil to an oil storage tank. The emergency treatment method can perform emergency and rapid treatment on the kitchen waste through a simple and short treatment process, avoids the influence on municipal waste treatment when a normal treatment device is under the repair or maintenance condition, and has a rational and practical process.

Description

technical field [0001] The invention relates to a treatment method for kitchen waste. Background technique [0002] Kitchen waste refers to food waste and food residues in families, schools, government canteens, and catering industries, and is the main component of municipal solid waste. my country's food waste is large in quantity, high in quality, and mixed, and it is food waste with Chinese characteristics. At present, kitchen waste has become a major public hazard to society. [0003] If the kitchen waste is not handled properly, it will not only endanger people's health, but also seriously pollute the environment. The moisture content of kitchen waste is as high as 80-90%. The seepage water in swill water can easily pollute the ground water through osmosis. When the temperature is high, the organic matter rich in swill will quickly ferment and rot, resulting in Escherichia coli and other pathogenic microorganisms will directly endanger human health. If it is directl...

[0005] For this reason, someone has developed a processing method for producing feed from kitchen waste, such as the Chinese patent "Regenerated Feed Preparation Process of Kitchen Waste" with the patent application number 02160496.7, which includes the reception of kitchen waste and the transportation between processes , sorting and dehydration, crushing, sterilization, drying, and granulation; there are many researchers and literature reports on the treatment methods of these food wastes, but in some occasions, due to equipment failure or maintenance, the processing of food wastes Under the condition that the treatment equipment cannot be used, the city also needs an emergency food waste treatment method, and these technical researches basically have no
