Resource utilization method for kitchen garbage and refrigeration retain-freshness device

Abstract

The invention relates to a resource utilization method for kitchen garbage, which comprises the following steps: a user registers an account through a platform client to become a platform member; thekitchen garbage refrigeration retain-freshness device and the special garbage bag are distributed to each user; a user divides the kitchen garbage into pre-meal garbage and post-meal garbage, whereinthe pre-meal garbage is put into a first refrigerating cabinet, and the post-meal garbage is put into a second refrigerating cabinet; the recovery is carried out periodically or is called for throughthe platform client; the pre-meal garbage is sent to a feed processing factory or a breeding factory through a special cleaning truck, and the post-meal garbage is sent to a designated place for centralized treatment; recyclable materials, other garbage and harmful garbage can be recovered at the same time; after the garbage with qualified classification is received, the user scans the code to score points, and enjoys the platform reward feedback. The invention relates to the refrigeration retain-freshness device, which is a special device in the resource utilization method for kitchen garbage, and is a core component for achieving the function of the platform and the recycling of kitchen garbage. According to the resource utilization method for kitchen garbage and the refrigeration retain-freshness device, the problems of high energy consumption of classification, recovery, reuse and post-treatment of kitchen garbage with huge quantity and difficult treatment can be solved from the source.

Description

technical field [0001] The invention relates to a resource utilization method of kitchen waste, in particular to an Internet-based method for classifying and reusing urban waste from the source; the invention also relates to a refrigeration and preservation device for kitchen waste. Background technique [0002] In our country, the per capita annual garbage production is 440 kg, and it is increasing at a rate of 10%. In cities, the amount of garbage dumps over the years has reached 6.6 billion tons, occupying more than 3.5 billion square meters of land, and two-thirds of large and medium-sized cities Surrounded by garbage, 1 / 4 of the cities have extended the solution to the garbage crisis to the countryside, and the secondary pollution of urban garbage has led to the deterioration of the ecological environment in the urban-rural integration zone. [0003] According to the "Investment Analysis and Prospect Forecast Report of China's Waste Disposal Industry 2017-2021" by China...

Problems solved by technology

[0005] The reality is that we have not classified the garbage before and after the meal, and the garbage is directly processed at the end. Since the pilot implementation of garbage classification in my country in 2000, the results have been minimal. The received basically is mixed garbage, and occasionally it has been processed. The sorted garbage is mixed together during the transportation of garbage trucks, and it still goes directly to the terminal treatment, such as incineration and landfill. On the one hand, the process of incineration and landfill will produce harmful substances, seriously pollute the air, and affect the ecological environment. adverse impact on the environment

On the other hand, the recyclable resources are landfilled, resulting in waste of resources
