A solid waste disposal plant refers to a complete production line or treatment system that uses a combination of specialized and systematic equipment and processes to classify, crush, sort, recycle, reduce, harmlessly dispose of, or convert solid waste, such as municipal solid waste, industrial solid waste, construction waste, sludge, hazardous waste, and medical waste, for energy utilization.
A solid waste disposal line is a fully automated or semi-automated production line for a specific type or multiple types of solid waste, from loading, pretreatment, sorting, processing, disposal, to final product output, through a scientifically planned and rationally configured "equipment + process + control system" system. Its goal is to reduce, recycle, and harmlessly dispose of solid waste.
Solid waste disposal lines systematically treat solid waste through scientific methods such as physical, chemical, biological, or thermal methods, changing its physical form, chemical properties, or biological stability. This approach aims to reduce volume and quantity, control hazardous components, and facilitate resource recovery or energy conversion, ultimately achieving environmentally friendly emissions and resource recycling.
The specific process flow of a solid waste disposal line varies depending on the type of solid waste (e.g., domestic waste, industrial solid waste, construction waste, kitchen waste, etc.) and the treatment goal (resource recovery/energy recovery/harmless disposal).

Solid Waste Disposal Line Process Flow:
1. Loading and Pretreatment: Receives and transports various types of solid waste to the treatment system for initial homogenization and pretreatment.
2. Crushing and Refining: Breaks large solid waste (e.g., furniture, plastics, construction waste, etc.) into smaller pieces for subsequent sorting or processing.
3. Sorting (Core Process): Efficiently separates recyclables (e.g., metals, plastics, paper, glass, etc.) from non-combustible/non-recyclable materials to improve resource recovery rates.
4. Resource Recovery: Recycles and reuses sorted high-value materials (e.g., metals, plastics, paper, rubber, etc.).
5. Storage/Transportation: Recyclables, fuel, ash, etc. are stored separately and transported to appropriate utilization or disposal sites.
Examples of Disposal Line Processes for Different Types of Solid Waste:
Municipal Domestic Waste: Volume Reduction, Harmless Treatment, and Energy Conversion: Crushing → Sorting → RDF/SRF/Incineration → Waste Heat Power Generation → Flue Gas Treatment → Slag Brick Making
Industrial Solid Waste: Resource Recovery and Harmless Treatment: Crushing → Sorting (Metal/Plastic/Fiber) → Recyclables Recovery → Hazardous Waste Separate Disposal/Incineration
Construction Waste: Resource Utilization (Recycled Aggregates): Coarse Crushing → Screening → Fine Crushing → Air Separation/Magnetic Separation → Recycled Aggregates/Non-Burning Brick Raw Materials
