Background
The kitchen waste is mainly domestic waste generated in production and living consumption, and comprises food processing waste, edible residues, leftovers and the like generated in families, schools, dining halls, catering industries and the like. Because the kitchen waste has four high characteristics of high oil content, high water content, high salinity and high organic matter content, the kitchen waste is extremely easy to decay and deteriorate, emits foul smell, is extremely easy to generate pathogenic microorganisms, and can bring serious pollution to the environment. Meanwhile, with the improvement of the living standard of residents in China and the rapid development of the catering industry, the discharge amount of kitchen waste in China is increasing day by day, and the utilization and treatment of the kitchen waste become problems to be solved urgently.
At present, the treatment method of small household kitchen waste mainly comprises the following steps: directly crushing, performing solid-liquid separation after crushing, and performing microbial treatment to prepare the fertilizer. These methods still have some disadvantages in use, such as:
1. directly crushing and discharging into a sewer: cutting, grinding and crushing the bulk kitchen waste by a physical method to form a liquid state, and discharging the liquid state into a sewer. The crushed garbage is not digested and still pollutes the environment after being discharged into a sewer, even blocks the sewer, and grease in the garbage is easy to condense into blocks to reduce the drainage capacity, so that the load of an urban sewage treatment plant and a garbage landfill is increased.
2. And (3) performing solid-liquid separation after crushing: and (3) performing solid-liquid separation on the crushed kitchen waste, and discharging a large amount of water to obtain solid which can be used as an organic fertilizer. Solid-liquid separation reduces the content of floatable oil in the kitchen waste, but has little influence on solid-phase crude fat, thereby reducing the composting effect.
3. Preparing fertilizer by microbial treatment: and adding microorganisms into the kitchen waste for degradation and fermentation to prepare the organic fertilizer. The existing equipment has limited treatment capacity for high-oil and high-salt kitchen waste, and in order to ensure the activity of microorganisms, a user is required to separate oil water in advance and wash salt with clean water, so that the operation is troublesome.
In summary, the existing kitchen waste treatment device and method have the problems of incomplete treatment, poor treatment effect, inconvenience in operation and the like.
