Process for preparing fertilizer from kitchen garbage

Abstract

The invention discloses a process for preparing a fertilizer from kitchen garbage. The process comprises the following steps: S1, collecting the kitchen garbage; different types of kitchen garbage are classified and then collected and stored in different containers; s2, performing classified inspection on the kitchen garbage; and different types of kitchen garbage are subjected to turning and sorting treatment, so that residues which cannot be treated are sorted out. According to the technology for preparing the fertilizer from the kitchen garbage, the kitchen garbage is classified, turned and sorted, the situation that the fertilizer preparation effect is poor and even a treatment machine is damaged due to residual foreign matter is avoided, the kitchen garbage is soaked and cleaned to reduce salt contained in the kitchen garbage, then the kitchen garbage is subjected to oil-water separation to obtain kitchen garbage recycled materials, and the kitchen garbage recycled materials are recycled. The method has the advantages that the process operation is simple and convenient, the salinization of the soil in the subsequent use process of the fertilizer is prevented, the social environment is protected, and the purpose of turning the kitchen garbage into wealth is achieved.

Description

technical field [0001] The invention relates to the technical field of kitchen waste treatment, in particular to a process for making fertilizer from kitchen waste. Background technique [0002] Kitchen waste refers to the waste generated in the daily life of residents and activities such as food processing, catering services, and unit meals, including discarded vegetable leaves, leftovers, leftovers, fruit peels, eggshells, tea dregs, bones, etc. The main sources are home kitchens, restaurants, restaurants, canteens, markets and other industries related to food processing. As we all know, the kitchen waste in people's daily life is organic matter and can be recycled. In rural areas, people can use kitchen waste to feed poultry, but in cities, because people do not feed poultry, they can only dump and discard kitchen waste in daily life, wasting social resources. [0003] Kitchen waste is an item that people produce every day. People have always hoped to turn these wastes ...

In rural areas, people can use kitchen waste to feed poultry, but in cities, because people do not feed poultry, they can only dump and discard kitchen waste in daily life, wasting social resources

[0003] Kitchen waste is an item that people produce every day. People have always hoped to turn these wastes into treasures. At present, there is no complete and mature treatment method. The common way is to fill the kitchen waste. Buried or incinerated, some of them are processed by stacking and fermentation, and finally produced into low-quality fertilizers. For example, the patent application No. 202110765127.2 discloses a process for processing kitchen waste into organic fertilizers. Garbage is collected as incoming materials, and the kitchen waste is recycled and processed through a complete and mature processing method of the system, and the kitchen waste is finally produced into high-quality organic fertilizers, which optimizes the original landfill or incineration of kitchen waste, and finally The treatment method of high-temperature fermentation and composting fermentation has achieved the purpose of turning kitchen waste into treasure; however, due to the use of high-temperature fermentation and composting fermentation, the process chain is long, it is easy to cause secondary pollution, and it is difficult to guarantee the treatment effect. Complicated and costly to participate
