Biological enzyme kitchen waste treatment equipment

technical field

The invention relates to the technical field of waste treatment, in particular to a biological enzyme kitchen waste treatment equipment for kitchen waste.

Background technique

Kitchen waste refers to food residues, residues and food processing wastes generated in the daily life of residents and in food processing, catering services, unit meals and other activities. Compared with other wastes, kitchen waste contains high moisture content, salt and oil. The characteristics of high content are that it is perishable and deteriorated, emits foul odor, breeds mosquitoes, and spreads germs. If it is not treated in time, it will affect the appearance of the city, damage the ecological environment, and even affect the health of citizens. important part.

In China, the proportion of kitchen waste in urban domestic waste is increasing year by year. Statistics show that the proportion of kitchen waste in China's urban domestic waste is roughly 40%-50%. In the past five years, China's major cities have actually generated an average of no less than 60 million tons of kitchen waste each year. Disposal of food waste has become a common concern around the world.

Commonly used treatment methods in the prior art are as follows:

Landfill method: Kitchen waste in many regions of my country is sent to landfills together with other household wastes for landfill treatment. Landfilling is the main method of innocuous disposal of domestic waste in most countries. Because kitchen waste contains a large number of degradable components, the stabilization time is short, which is conducive to the restoration and use of landfill sites, and the operation is simple and fast, so it is widely used. According to statistics, in 2017, in the harmless treatment of urban waste, 60% of the domestic waste was carried out by landfill method. However, the landfill method requires a large area and high investment, and the leachate in the garbage can easily cause the pollution of the surrounding soil and groundwater. At the same time, people's awareness of the availability of kitchen waste has become more and more extensive, and the landfill rate of kitchen waste has shown a downward trend. In other countries, there have been regulations prohibiting the entry of kitchen waste into landfills for disposal.

Incineration method: The incineration method can quickly reduce the amount of waste, and has a high efficiency in treating kitchen waste, and finally produces about 5% of residues that are conducive to disposal. Incineration is carried out in a special incinerator, and the generated heat energy can be converted into steam or electric energy, so as to realize energy recovery and utilization, but this method also has the characteristics of high investment and serious smoke and dust pollution. In addition, the kitchen waste has high moisture content, low calorific value, and poor incineration effect. If the incineration method is still used, auxiliary fuel needs to be added when the kitchen waste is burned, resulting in the problem of increased investment.

Traditional composting method: The traditional composting method uses microorganisms such as bacteria, yeast, fungi and actinomycetes in the garbage or soil to degrade (digest) the organic matter in the garbage through a biochemical reaction, forming a similar corrosive soil. substances, used as fertilizers and to improve soils. The method is particularly suitable for the treatment of kitchen waste, and can effectively decompose oils, carbohydrates, proteins and other substances in the kitchen waste, and the generated organic fertilizer can be used as a fertilizer to improve the nutrient content of the soil. However, since kitchen waste has not been properly subdivided, it contains some harmful substances that cannot be decomposed. When used as organic fertilizer, the harmful components contained in it are absorbed by plants, which may eventually endanger human health. At the same time, if there is a phenomenon of high oil and high salt in the garbage, the microorganisms contained in the garbage are not enough to decompose it completely or take a long time, which is not suitable for large-scale promotion.

Crushing and straight-discharging method: This method is widely used in European and American households and is the main method to deal with a small amount of scattered kitchen waste. It is discharged into the urban municipal sewer network, merged with urban sewage, and enters the urban sewage treatment plant for centralized treatment. The crushing method has the advantages of low price and simple technology for the treatment of a small amount of scattered kitchen waste, such as household kitchen waste. However, since China's sewer network is different from that of European and American countries, if the kitchen waste crushing and straight-discharging method is widely adopted in China, it is easy to block the sewers and pollute the surrounding water sources.

Feed method: kitchen waste has huge potential in the current feed market. Kitchen waste as a raw material has low price, huge supply, rich nutrition, large profit range, and strong market competitiveness. There are generally two ways to turn kitchen waste into feed: (1) Biological treatment to make feed: The principle is to add the cultured bacteria to the kitchen waste for sealed storage, and the bacteria to multiply and kill pathogenic bacteria to make feed. (2) High-temperature sterilization to make feed: The principle is to use the principle of high-temperature sterilization to kill viruses, and then process it into feed after crushing, which can be eaten by livestock. However, the disadvantage is that kitchen waste is not subdivided, and it may contain ingredients that are harmful to people and livestock. At the same time, kitchen waste is high in water content and rich in nutrients. It is easy to deteriorate and produce toxins during transportation. It may endanger the health of livestock and ultimately human health when it is made into feed.
