Kitchen waste separation treatment system

Abstract

The invention discloses a kitchen waste separation treatment system. The system is composed of a kitchen waste solid-liquid separation device, a conveying unit and a post-treatment unit in sequence; the kitchen waste solid-liquid separation device is used for separating solid and liquid in kitchen waste; the conveying unit is used for collecting and conveying the solid and the liquid separated by the kitchen waste solid-liquid separation device to the post-treatment unit; and the post-treatment unit is used for conducting harmless treatment and resource treatment on the received solid and liquid. By means of the kitchen waste separation treatment system, meal materials can be treated in a centralized manner; meanwhile, solid-liquid separation can be completed, and after being independently packaged, solid matter is subjected to harmless treatment and resource utilization, energy is generated, and finally the solid matter becomes organic fertilizer to return to farmland; after liquid matter is treated, water with the quality reaching the standard above the IV class can be obtained and discharged on site, water is supplemented to inland rivers, and the surrounding water ecology is improved; and by means of application of the system, environment pollution can be avoided, and the kitchen waste treatment difficulty and treatment cost are greatly reduced.

Description

technical field [0001] The invention relates to the field of kitchen garbage treatment, in particular to a kitchen garbage separation and treatment system. Background technique [0002] Kitchen waste refers to food waste and food residues from families, schools, public canteens and catering industries, and is the main component of municipal solid waste. With a population of 1.3 billion, China is the most populous country in the world. The huge amount of daily food consumption coupled with some unhealthy traditional eating habits leads to an astonishing waste every year. In recent years, with the rapid development of my country's economy, the retail sales of the catering industry have grown at a rate of 20% per year, and kitchen waste will also become larger and larger like a snowball. Calculated on the basis of 1 ton of kitchen waste produced per 10,000 people per day, there are as many as 130,000 tons of kitchen waste in the country every day, and 50 million tons of kitche...

AI Technical Summary

Problems solved by technology

In addition, the current treatment methods of urban waste are usually incineration and landfill. Since the moisture content of kitchen waste is usually as high as 80%, the calorific value can reach 2100-3100 kJ / kg. If it is incinerated together with other waste, it will not meet the requirements The calorific value requirements of waste incineration power generation will instead lead to insufficient combustion of the incinerator and produce dioxins; if it is landfilled with domestic waste, it will also be unsuitable for disposal due to the high water content of kitchen waste, and a large amount of organic matter will be wasted. Kitchen waste needs to be handled separately

[0004] At present, the processing system of kitchen waste is mainly based on foreign technology. Due to the differences in eating habits between the East and the West, the use of waste disposal machines designed for families in Western countries in Chinese families will have the problem of incomplete disposal of residual waste

Some pointed out that garbage can be compressed to solve the problem of under-loading in garbage transportation, and some manufacturers have also begun to independently develop products, such as a kitchen garbage shredder developed and produced by a company in Zhejiang Province. The inertial force crushes the garbage, and then cuts and grinds again through the relative movement of the tooth plate and the tooth field. The crushed garbage is washed away with the sewer. However, due to the immature technology in the equipment developed by domestic imitation, the product quality varies. Qi, consumers are also difficult to choose

Generally speaking, these processors have a single specification. When installing, it is necessary to consider whether there is enough space when the home kitchen is decorated, and whether the circuit pattern is allowed. Moreover, the remaining materials in the kitchen are mostly rich in oil, protein and polysaccharides.

[0005] Organic matter is a great waste in terms of environmental protection and resource recycling; in the survey, it was found that the existing waste disposal systems in the market should not input too much kitchen waste at one time during work, otherwise it will easily cause Clogged sewers, thus increasing the pressure on sewage treatment plants and natural rivers to biodegrade
