The significance and required equipment for the treatment of stale garbage

The disposal of aged waste is a critical measure to liberate land, protect the environment, and promote sustainable development. Through waste treatment equipment, we can transform garbage into valuable resources, enabling the continuous growth of a circular economy. The key to waste treatment lies in effective waste sorting and the use of advanced technology and equipment to purify and treat harmful substances within the waste. Only through waste treatment can we improve public health, control pollution, reduce waste generation, and ultimately build a green and environmentally friendly society.

I. Importance of Treating Aged Waste: The significance of dealing with outdated waste is multifaceted:

Reutilization of Land Resources: Processing waste and recovering its resources contribute to releasing land previously occupied by landfills. Once restored, this land can be reused, playing a significant role in alleviating urban land shortages.

Environmental Protection and Pollution Control: Old waste contains numerous harmful substances; if allowed to accumulate over time, it will cause persistent pollution to soil, groundwater, and air quality. Adopting harmless treatment methods can effectively prevent the spread of pollutants and protect the ecological environment. Waste leachate and greenhouse gases (such as methane) produced by aged waste are significant environmental hazards. Through the treatment process, emissions of leachate can be significantly reduced, and methane and other gases can be collected and utilized, thereby mitigating the impact of the greenhouse effect.

Reduction of Municipal Solid Waste Generation: Waste sorting and resource utilization can greatly decrease the total amount and weight of waste, improving waste disposal efficiency and reducing the need for new landfills.

Resource Regeneration: Advanced sorting technologies and equipment can extract useful resources, such as metals, combustibles, and organics, from waste. These resources can then be reused or converted into energy sources, like biomass energy or recycled materials. Public Health and Safety: Dealing with waste contributes to improving sanitation conditions and protecting residents' health by preventing the spread of pathogens. Promotion of Sustainable Development: The regeneration of waste resources supports the rise of a circular economy, aligning with the nation's advocacy for a green development philosophy. It holds profound implications for establishing a sustainable social development model. In summary, treating aged waste is not only an effective solution to past environmental issues but also a vital pathway to promoting resource recycling and the development of an environmentally friendly society.

II. Main Components of Aged Waste Treatment Equipment:

Pre-treatment Equipment:

Material Conveying Systems: Such as chain feeders, used to steadily and continuously transport aged waste to subsequent processing lines.

Primary Crushing Equipment: Like jaw crushers, primarily designed for breaking down large pieces of waste, e.g., concrete and bricks.

Intermediate Fragmentation Equipment: Examples include hammer mills or impact crushers, which further reduce the size of initially crushed waste to meet the required particle size for subsequent processing.

Screening Equipment:

Drum Screeners: Utilize the rotation of drums and sieving holes to classify waste according to particle size.

Vibrating Screens: Further separate materials based on different particle diameters, distinguishing between different grades of aggregates and other materials.

Air Classification Devices: Use airflow technology to separate lightweight materials like plastics and paper from heavier ones.

Magnetic Separators: Employ magnetic fields to separate metallic fragments from waste.

Sorting Equipment:

Manual Sorting Platforms: Staff manually classify waste on these platforms, removing recyclable items.

Intelligent Sorting Systems: Utilize photoelectric, near-infrared, and AI image recognition technologies to perform intelligent identification and sorting tasks.

Biological Treatment Systems:

Composting Equipment for Organic Waste: Facilitates fermentation treatment of organic waste, converting it into organic fertilizer.

Bioreactors: Employ microorganisms to degrade organic matter, producing biogas or other forms of biomass energy.

Resource Recovery Systems:

Garbage Compaction and Baling Equipment: Used to compress and bale sorted materials for easier transportation and further reuse.

Waste Recycling Equipment: For instance, machinery that turns construction waste into recycled building materials.

Ancillary Equipment and Supporting Facilities:

Material Conveying Equipment: Such as belt conveyors and bucket elevators, used for transferring materials during the treatment process.

Control Systems: Centralized electronic control systems automate the monitoring and control of the entire production line.

Ventilation and Dust Removal Systems: Supply the necessary airflow for air classification and simultaneously reduce dust pollution.

Warehouses and Storage Equipment: Temporarily store raw materials or processed materials. Through the combined operation of these devices, aged waste can be efficiently processed, achieving the goals of reduction, harmlessness, and resource utilization.
