Technical field

The present invention relates to the technical field of domestic waste treatment, in particular to a domestic waste treatment device and method.

Background technique

The resource utilization and reduction of domestic waste is known as a major trend in environmental protection measures in the world today. Domestic waste is considered to be the second largest pollution source in cities after domestic sewage due to its high pollution index. Realizing the recycling of domestic waste can effectively reduce the amount of urban domestic waste, improve the sanitary environment of the city, and prevent the occurrence of diseases.

Domestic waste refers to the leftovers of food from catering industries such as villages, communities, restaurants, hotels, and public canteens such as families, enterprises, institutions, and schools. As well as packaging bags, waste clothes, broken tableware, broken glass, bricks, plastic pieces, packaging boxes, wood chips, etc., the discards generated in the life process are generally divided into recyclable household garbage, kitchen waste household garbage, hazardous household garbage, and others Domestic garbage, etc.

Recyclable household waste mainly includes paper, plastic, glass, metal, etc., of which paper mainly includes newspapers, periodicals, books, various packaging papers, office paper, advertising paper, paper boxes, etc.; plastics mainly include various Plastic bags, plastic packaging, disposable plastic lunch boxes and tableware, toothbrushes, cups, mineral water bottles, etc.; glass mainly includes various glass bottles, broken glass pieces, mirrors, light bulbs, thermos bottles, etc.; metal objects mainly include cans, cans , Toothpaste skins, etc.; fabrics mainly include discarded clothes, tablecloths, face towels, school bags, shoes, etc.

Kitchen waste includes food wastes such as leftovers, bones, vegetable roots and leaves.

Hazardous domestic waste refers to domestic waste that may cause harm or potential harm to the environment without proper disposal. Such as fluorescent tubes, dry batteries, various chemical batteries and other items that contain harmful substances.

Other domestic wastes include bricks, ceramics, muck, toilet waste paper and other wastes that are difficult to recycle other than the above-mentioned types of domestic waste. Landfilling can effectively reduce the pollution of groundwater, surface water, soil and air.

Domestic waste has the following characteristics.

1. High organic matter content: rich in starch, protein, meat, oil, etc.

2. High water content: As a leftover material in a meal, the water content of slick feet is about 70%.

3. High oil and salt content: Due to my country's dietary habits, compared with foreign food and household waste, my country's food and household waste (including swill) has a higher output and also has a higher oil and salt content.

4. Hazardous: Domestic garbage is very easy to deteriorate, rot, decompose organic matter, breed mosquitoes and flies, spread diseases, produce a lot of toxins and emit odorous gases, and pollute water and the atmosphere.

5. Strong resource: Compared with other domestic garbage, it has the characteristics of high moisture content, organic content, salt and oil content, and rich nutrients, and has great recycling value. Recycled plastics, waste clothes, packaging boxes, wood chips, etc. can be used as high fuel value fuels for incineration of domestic waste for power generation. Recycled bricks, broken glass, broken tableware, etc. can be used as household waste fillers.

At present, our country is promoting the classified collection of domestic waste, not to mention that our country's domestic waste has not yet formed the habit of classified storage. After most of the domestic waste is transported to the domestic waste transfer station, it is mixed. At present, the basic technical process of domestic waste classification in my country is: domestic waste is transported by a plate-chain quantitative conveyor to a manual sorting conveyor before the sieve, after preliminary screening, the drum-type sorting and screening are carried out, and finally sent to the sieve conveyor. The shortcomings of this process are obvious, the manual sorting environment is harsh, no harmless disposal is performed, and it cannot be directly used as resources.

At present, there are few community-level domestic waste treatment equipment, and the degree of automation is low. Many community-level domestic waste treatment equipment need to sort out the debris in the domestic waste when processing, wasting a lot of manpower and material resources, and a lot of Once the equipment is incompletely sorted and mixed with broken glass, bones, chopsticks and other debris, it will cause the equipment to jam. It needs to be carefully cleaned before it can work again. What's more, it may require professional maintenance before it can work normally again. The processing equipment is inefficient.
