Method for collecting, separating, storing, transporting and reutilizing kitchen waste

Abstract

The invention discloses a method for collecting, separating, storing, transporting and reutilizing kitchen waste. Specifically, the method comprises the following steps that: the on-site solid-liquid separation is carried out on the kitchen waste in a restaurant; oil-water separation is carried out on the kitchen waste on a special mobile kitchen waste disposal car for separating swill-cooked dirty oil and waste water, and then the on-site purifying treatment is carried out on the waste water, and the water quality after treatment reaches the emission standard for national GB8978-1996 town primary and secondary sewage treatment plants. The equipment adopted by the method belongs to standardized products commonly used in industry, is reliable in running, is mature in technology, is simple in structure, is convenient to maintain, and is low in cost. The method provided by the invention can be used for collecting, separating, storing and transporting the kitchen wastes, and carrying out harmless minimized and resourcing treatment on the kitchen wastes in thousands of restaurants in cities and towns in a timely and standardized manner, is particularly suitable for relevant departments of the government to conduct standardized and scientific management on the kitchen waste, and has good industrial practicability, novelty and creativity.

Description

technical field [0001] The invention relates to a method for harmless volume reduction and resourceful treatment of kitchen waste; in particular, it relates to a method for collecting, separating, storing, transporting and resourceful treatment of kitchen waste, belonging to the field of environmental protection and chemical engineering. technical background [0002] With the continuous improvement of people's daily life, the amount of kitchen waste is increasing. Standardized and low-cost unified recycling, utilization and management of food waste can make it harmless, reduce and recycle, and put an end to " Putting "gutter oil" on the dining table and maintaining people's food hygiene and health is a major concern in today's society and has great environmental and social significance. [0003] There have been many reports on methods or equipment for food waste treatment; in CN202028601U, "a zero-emission food waste treatment device" is disclosed, and "the process of dehydr...

Problems solved by technology

[0003] There have been many reports on methods or equipment for food waste treatment; in CN202028601U, "a zero-emission food waste treatment device" is disclosed, and "the process of dehydration, drying, and evaporation of food waste" is disclosed. The above method requires a large amount of energy, and has the disadvantages of high energy consumption and high processing cost; similarly, in CN202028604U, "a kind of high-efficiency pretreatment equipment for food waste" is disclosed, and "preheating and hydrolysis of food waste , water evaporation, sterilization, oil extraction, and powder drying process", which has the disadvantages of long process, high energy consumption, and high cost; Garbage trucks have a very limited amount of garbage to process. Usually, the treatment of kitchen waste includes: separation of solid waste and swill, harmless and volume-reducing treatment of solid waste (such as high-temperature sterilization Post-bacteria feed, or organic fertilizer...etc.), and waste water purification standard treatment (usually long-term anaerobic fermentation, aerobic fermentation, air flotation, sedimentation...etc. ) after discharge and other three processes; the above three processes are indispensable, only when the waste residue and waste water are all harmless and reduced, and meet the discharge standards stipulated by the state, the above-mentioned "Mobile Kitchen Waste Treatment Device" It can be called a real special vehicle for the harmless treatment of kitchen waste; the national standard width of the general car body is 2.4 meters, and the length is 10-20 meters; Each restaurant next to it collects food waste; therefore, the device of CN201849886U "Mobile Food Waste Disposal Device" cannot make the food waste carry out all the steps of the harmless reduction treatment of food waste on the narrow body plate.
