Description

Food waste and kitchen waste co-processing system and processing method thereof
Technical Field
The invention relates to the technical field of garbage treatment, in particular to a system and a method for cooperatively treating food waste and kitchen waste.
Background
The food waste is mainly generated from the leftovers in restaurants, dining halls and other catering industries, and has the characteristics of extremely high water content (about 85-90 percent), high content of grease and salt, easiness in eating, easiness in smelling and the like.
The kitchen waste mainly refers to waste leftovers and leftovers in daily cooking of residents, and has high water content (about 60-80%).
At present, both types of waste are treated separately;
the anaerobic digestion process is adopted for the main body treatment process of the food waste,
because domestic food waste has high water content and is generally mixed with kitchen waste for composting, the food waste is rarely treated by composting independently, and the application of the food waste in the field is restricted by overhigh salt content.
The feed treatment technology mainly adopts a physical means to heat the food waste at high temperature, dry, sterilize and remove salt and the like, and can finally generate available substances such as protein feed additives, reclaimed water, methane and the like. The technical product is a feed for the breeding industry, has potential homologous pollution, is closely related to human health, has larger safety risk and is not recommended.
The biochemical microbe treating technology includes selecting high temperature composite microbe strain with high life activity and proliferation capacity, high temperature high speed fermentation of meat, expired food, food refuse and other organic waste in biochemical treating apparatus to degrade and convert various organic matters completely and to prepare microbe fertilizer bacterial preparation and biological protein feed. As the process needs to mix a large amount of other organic matters (such as bran, bran and the like) in the food waste, the reduction effect of the technology is poor, the product market is not easy to solve, and in addition, the process has higher operation energy consumption.
From the viewpoint of the advanced foreign kitchen waste treatment technology, the kitchen waste treatment is mainly based on biochemical treatment, wherein the treatment process combining anaerobic treatment and aerobic treatment is generally accepted and adopted.
