Restaurant and kitchen waste integrated treatment method

Abstract

The invention discloses a restaurant and kitchen waste integrated treatment method which is characterized by comprising the following steps of firstly, carrying out liquid-solid separation on restaurant and kitchen waste and respectively carrying out recovery treatment on the separated solid and liquid, wherein the process of carrying out recovery treatment on the separated solid comprises the following steps of firstly grinding the separated solid into particle paste, carrying out dehydration and wiping treatment on the particle paste to obtain waste oil and waste residues containing a small amount of water, recycling the waste oil and drying the waste residues to obtain unconfined solid organic fertilizer particles; and the process of carrying out recovery treatment on the separated liquid comprises the following steps of carrying out oil-water separation and recycling oil obtained after separation, carrying out biochemical treatment on water obtained after separation and recycling the obtained clean water. By the method disclosed by the invention, the restaurant and kitchen waste can be effectively locally decomposed and treated into the recovered oil, the clean reuse water and a solid organic fertilizer and the secondary pollution cannot be caused to the surrounding environment. The restaurant and kitchen waste integrated treatment method has the advantages of good recycling and utilizing effect, energy saving, water source saving and comprehensive utilization.

Description

technical field [0001] The invention relates to an integrated treatment method for kitchen waste. Background technique [0002] The solid content of food waste is very low, and the daily food waste of each restaurant will have a large difference, which leads to the particularity of food waste treatment. Kitchen waste is produced in the kitchen (or food, food processing factory) where people have to rely on food for daily living, but it pollutes the place where the food is made. The main reason is that food waste contains a large amount of organic mixtures such as protein, fat, and plant fiber, which are rich in nutrients, and are easily corrupted to produce odor and liquid, polluting the surrounding environment. [0003] The management of urban kitchen waste treatment is an important task to develop the circular economy, protect the health of the people, and maintain the cleanliness and cleanliness of the city. In recent years, some first-tier cities in my country have suc...

AI Technical Summary

Problems solved by technology

The shortcomings of this food waste treatment equipment are: 1. The level of treatment technology is not thorough, and the water content of the solid part after treatment is high, and the relevant state departments still need to reprocess after recycling

2. The working environment is poor, and the processing technology is not comprehensive, especially the high-temperature fermentation, which not only wastes energy, but also produces peculiar smell, and there is a hidden danger of polluting the environment

3. The added value of recycled products is low, which affects the comprehensive utilization of kitchen waste
