The screening and treatment of urban garbage is of great significance for resource recycling, environmental pollution control, and the improvement of ecological environment quality. Through precise screening, effective resource recycling and reuse can be achieved, reducing the amount of waste landfilling, protecting land resources, and promoting the development of circular economy. The screening and treatment of urban waste is one of the key factors in building green cities and achieving ecological civilization construction.

The screening and treatment of urban garbage has important multiple meanings, mainly reflected in the following aspects:

1. Resource recycling and reuse:

Garbage screening is the initial stage of garbage classification, which can separate recyclable materials such as metal, glass, plastic, paper, wood, etc. from garbage. These materials can be reused after processing, which helps to protect natural resources.

2. Reduce environmental pollution:

By careful screening, hazardous waste (such as used batteries and electronic waste) can be separated from other waste to prevent harmful substances from leaking into soil and water sources, reducing the risk of environmental pollution.

3. Reduce the amount of waste landfill:

After screening, many recyclables and organic waste are recycled or decomposed, significantly reducing the total amount of waste that needs to be landfilled or incinerated, reducing the burden on landfills, and extending their operating time.

4. Protecting land resources:

Reducing the land required for landfilling can avoid excessive consumption of land resources. Meanwhile, classified inorganic materials can be used to produce recycled building materials, replacing natural resources and indirectly protecting land resources.

5. Promote the recycling of economic resources:

Garbage classification can promote the development of circular economy and establish a closed-loop system of "resources products renewable resources", which is in line with the concept of sustainable development.

6. Improve the quality of the ecological environment:

After sorting the organic components in household waste, it can be composted or anaerobically digested to convert them into fertilizers or biomass fuels, which not only solves the problem of organic waste treatment, but also helps to improve soil and optimize the ecological environment.

Overall, the classification and treatment of urban waste is not only an important method to solve the problem of solid waste in cities, but also a key factor in building green cities and promoting ecological civilization construction.

Solid waste treatment equipment can generally be divided into the following types based on different treatment methods and technical requirements:

1. The crusher equipment includes a coarse crusher and a fine crusher, mainly used to crush large solid waste into smaller particles for subsequent processing and recovery.

2. Screening machinery: such as drum screens, used to classify and screen waste according to its size, shape, and density, achieving waste classification and separation.

3. Transmission equipment: including conveyor belts, screw conveyors, etc., used to transport waste from one step to another during the processing.

4. Garbage compactor: A solid waste packaging machine that can compress and package solid waste, reduce volume, facilitate storage and transportation, and also contribute to resource recycling and utilization.

5. Material sorting equipment, such as magnetic separators and air separators, use magnetic or aerodynamic principles to separate metals, lightweight materials, etc. from mixed waste.

6. Incineration equipment: Incinerators are used to incinerate a portion of organic solid waste at high temperatures, in order to achieve the goal of reducing and recovering heat energy.

7. Resource recycling equipment: specialized equipment used to process specific solid waste such as construction waste, used tires, and metal waste, such as steel bar strippers, wood classification equipment, etc.

With the acceleration of urban construction and renovation, the pollution caused by construction waste and the phenomenon of surrounding cities are becoming increasingly prominent. As of 2020, the total amount of construction waste in China reached 2.6 billion tons. However, in terms of resource recycling, China's construction waste recycling rate is less than 10%, far lower than the 90% in European and American countries and the 95% in Japan and South Korea. At present, the treatment method still remains at the extensive stage of landfilling and stacking. Faced with the serious problem of building waste besieging the city, proper disposal and reuse have become urgent challenges for urban development. The new Solid Waste Pollution Prevention and Control Law was officially implemented on September 1, 2020, making the treatment, resource utilization, and environmental protection of construction waste gradually the focus of investment.

Solid waste treatment industry chain: In terms of the upstream and downstream of the hazardous waste treatment industry, the upstream of solid waste treatment mainly involves the manufacturing of various solid waste treatment equipment and transportation equipment; The midstream mainly includes the treatment of various solid wastes. At present, China's solid waste treatment technology is mainly divided into three categories: resource recycling, incineration, and landfill.
