Kitchen garbage dehydration composting process and system

Abstract

The embodiments of the invention disclose a kitchen garbage dehydration composting process and system, and relates to the technical field of garbage disposal. The kitchen garbage dehydration composting process comprises the following steps: sorting is conducted according to quality, specifically, impurity removing is conducted on mixed garbage, and kitchen garbage is sorted out; solid-liquid separation is conducted on the kitchen garbage, specifically, the kitchen garbage is crushed and extruded to separate most of water to generate solid residues and organic waste liquid; the solid residue istransported and treated, specifically, the solid residue is transported through a compression vehicle, and the solid residue and garden waste are cooperatively composted; and the organic waste liquidis degraded, specifically, the organic waste liquid is degraded by utilizing biological hydrolysis equipment. According to the kitchen garbage dehydration composting process and system, the problemsthat leachate is easily generated in the compression transportation process of the kitchen waste organic wet garbage, and consequently the environment is polluted, and the problems of insufficient aeration and high back-end wastewater treatment pressure caused by high water content in the aerobic composting process can be solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of garbage treatment, and in particular to a process and system for dehydrating and composting kitchen waste. Background technique [0002] In the garbage classification regulations, kitchen waste is mainly divided into: kitchen waste and other kitchen waste, collective canteens of enterprises and institutions engaged in catering business activities, military forces, schools, etc., and enterprises engaged in catering business activities in food processing, catering service The food residues and food processing wastes generated in activities such as catering, unit meals, etc. are all food wastes with high organic content. , discarded vegetable leaves and other wet garbage. At present, the treatment methods of kitchen waste in my country mainly include anaerobic fermentation and aerobic composting. Anaerobic fermentation and aerobic composting can be carried out according to the comp...
