Problems solved by technology

Feeding pigs with untreated food waste can easily lead to disease transmission and cross-infection between humans and animals. This form of food chain hides a huge risk of pathogen transfer and spread
"Waste oil" contains toxic substances such as aflatoxin and benzene, which will return to people's dining tables through illegal channels, and will cause chronic diseases and even cause cancer when eaten by people, causing great harm to people's health.
Food waste contains a lot of leftover soup and rancid water, which are easy to leak during collection and transportation, affecting the urban environment
Food waste is directly landfilled, which will cause serious pollution of groundwater

Embodiment Construction

[0024] Such as figure 1 Shown, the processing steps of the kitchen waste treatment method of the present invention are as follows:

[0025] 1. Receiving and conveying: unload the kitchen waste to the receiving bin, and convey it to the broken bag sorting system through the spiral receiving and conveying system, in which the liquid material is conveyed to the liquid storage tank through the pipeline.

[0026] 2. Broken bag sorting: In the broken bag sorting system, the food waste delivered is first broken through the bag breaking device to break the plastic bags wrapped in the food waste, and the wrapped materials are released, and then the plastic bags are separated by the sorting device. , plastic bottles, cloth strips, cans and other sundries are sorted out, and the solid content rate is 30%; after the sorting is completed, solid-liquid separation is carried out, and the separation of solid materials and liquid materials is realized through a screen, which can be Take the f...

Abstract

The invention relates to a kitchen waste treatment method and equipment. The method comprises the following steps of bag breaking separation, breaking pulping, sand removing, pyrolysis, three-phase separation. The steps are sequentially carried out, and normal-temperature anaerobic fermentation is carried out on water obtained through three-phase separation to generate marsh gas; and the marsh gas is used for fuel of a steam boiler in the pyrolysis process so as to generate heat to be supplied to a pyrolysis system. An efficient treatment method for treatment of kitchen waste separation, pulping, separation and resource utilization is provided. Treatment processes are combined, and through combination of technical advantages of kitchen waste separation, puling, oil and slag resource utilization, water up-to-standard releasing, and resource utilization, the aim of kitchen waste treatment is achieved.

Description

technical field [0001] The invention relates to the fields of environmental protection and waste comprehensive utilization, in particular, a treatment method for sorting, pulping and separating food waste, and a method for harmless treatment and resource utilization of separated oil, water and slag. Background technique [0002] Food waste has complex components and is difficult to deal with, requiring effective sorting and separation. Food waste contains a large amount of organic matter. Effective recycling and utilization not only realize the harmless and reduction treatment of food waste, but also realize the resource utilization of food waste, which reduces the pollution to the environment and protects the environment. people's health. [0003] With the continuous improvement of economic development and people's material living standards, the amount of kitchen waste is increasing day by day. Food waste is fed to pigs without treatment, or is recycled by unscrupulous ...
