With the rapid development of China's economy and urban construction, the urban population continues to increase, people's living standards continue to improve, and household waste also increases accordingly. With the continuous deepening of urbanization, garbage, as a metabolic product of cities, has become a burden on urban development. Garbage is still mostly piled up outdoors, and its harm to the environment is becoming increasingly serious. Therefore, it is urgent to handle urban household waste in an environmentally friendly and economical manner. The existing waste disposal methods include land, river, sea, landfill, composting, incineration, and recycling.
At present, the majority of garbage disposal is mainly through landfilling, accounting for about 70% of the total processing capacity. This method is used in most parts of the world, especially in underdeveloped areas. This method has the characteristics of low construction cost, low operating cost, simple operation, and large processing capacity. But there are also many drawbacks:
1. Large land occupation, difficult site selection, and high land acquisition costs;
2. A large amount of resources are wasted in garbage, which is artificially transformed into resources that cannot be planted. The huge wealth thrown away cannot meet the needs of resource disposal;
3. Serious environmental pollution. Due to the insufficient construction of existing landfills to meet the requirements of sanitary landfills, bacteria and toxins in the garbage continue to infiltrate downwards, polluting the land and water quality.
As accumulation increases and time prolongs, pollution spreads to the surrounding areas and deep underground, posing a threat for thousands of years. The toxic gas emitted from garbage spreads to the surrounding area, forming three-dimensional pollution in the air, surroundings, and underground. Although many developed regions and some relatively developed cities in China have established a small number of "sanitary landfills" to reduce some pollution, there are still many environmental pollution problems caused by inadequate technology, which cannot be fundamentally solved.
Therefore, the advantages of garbage classification equipment are highlighted. Using garbage classification equipment to recycle household waste, accurately classify urban household waste, and then adopt appropriate treatment methods according to the different properties of classified waste to achieve recycling and utilization, truly realizing harmless, reduced, and minimized waste hazards, reducing human demand for natural resources, and achieving sustainable resource utilization. Therefore, the application prospects of garbage classification equipment are very broad. Through processes such as unified garbage supply, automatic garbage sorting system, air separation system, and magnetic separation system, various types of garbage in urban and rural areas are classified into inorganic matter, sand, organic matter, non recyclable combustibles, plastic film, ferromagnetic materials, etc.
The above-mentioned waste and separation purity can reach over 85%, and the separation rate of plastic film waste can reach over 90%, laying a solid foundation for the next step of "resource utilization and industrialization" of garbage treatment. Processing and increasing the amount of waste incineration. Reducing by nearly four fifths and using garbage to handle it has saved considerable operating costs.
