Organic waste resource pretreatment system and method

Abstract

The invention provides an organic waste resource pretreatment system and method. The organic waste resource pretreatment system comprises a sorting module and a treatment module, the sorting module comprises a material receiving pool, a sorting machine, a mechanical sorting area, a recycling bin and a cutting machine, and the treatment module comprises a cooking machine, a presser, a pulverizer and an insect feed bin. According to the system, organic waste such as food waste, kitchen waste, food market waste, vegetable and fruit waste, food processing leftovers and expired food can be treated, sorting and cutting of the organic waste are achieved through the sorting module, pollution-free conversion from the organic waste to insect feed is achieved through the treatment module, plastic, glass and the like are sorted out and recycled, treated byproduct grease can be used as biodiesel or chemical raw materials, separated soup is reused, and therefore recycling and harmless pretreatment of the organic waste is achieved, the treatment efficiency is high, and the investment cost is low.

Description

technical field [0001] The invention relates to the technical field of organic waste treatment, in particular to a pretreatment system and method for organic waste resource utilization. Background technique [0002] With the rapid development of the economy, people's living standards are also constantly improving, which has led to the vigorous development of the catering industry, and thus produced a large amount of organic waste, including catering waste, kitchen waste, vegetable waste, fruit and vegetable waste, food processing Leftovers, expired food, etc. Improper disposal of these organic wastes will cause great pollution to the environment and waste of resources. [0003] The most traditional garbage disposal method is incineration. The garbage is dehydrated and dried and then directly incinerated. This treatment method is the most harmful to the environment and has been basically banned at present. Another common treatment method is to send organic waste, etc. to farm...

AI Technical Summary

Problems solved by technology

[0002] With the rapid development of economy, people's living standard is also constantly improving, which drives the vigorous development of the catering industry, and thus produces a large amount of organic waste, including Catering waste, kitchen waste, vegetable waste, fruit and vegetable waste, food processing scraps, expired food, etc. Improper handling of these organic wastes will cause great pollution to the environment and waste of resources

[0003]The most traditional garbage disposal method is incineration, which dehydrates the garbage and then incinerates it directly. This treatment method is the most harmful to the environment and has been basically banned at present; another The more common way to deal with it is to send organic waste to the farm as feed, such as pig feed, but if the waste contains germs, it will be easier to cause large-scale plague, which will bring direct losses to the breeding industry, and may even Can cause illness in people who eat meat

In addition, organic waste can also be used for retting to make organic fertilizer, but the processing time is too long, usually more than 2 months, and the air in the processing site will also smell very bad

At present, the more advanced organic waste treatment method is to use liquid oxygen fermentation technology to ferment organic waste to form combustible gas, and the slag can be used as fertilizer. This treatment method can realize waste utilization to a large extent, but the cost is relatively high, and The treatment process will produce a large amount of sewage, which requires secondary treatment of sewage, and improper treatment will cause secondary pollution
