General solid waste is further divided into solid waste, semi-solid waste and unconventional solid waste solid waste: this is the more common form of general solid waste, including solid materials, such as lumpy, granular and powdery waste.
Disposal of solid waste:
Preparatory treatment: including crushing, screening, grinding, compression, etc., for further disposal.
Physical disposal: Uses the physical and physical and chemical properties of solid waste to sort or separate valuable or hazardous substances from it. Generating chemical transformations from solid waste**Valuable substances and energy. Calcination, roasting, sintering, thermal decomposition, incineration, all belong to chemical processing methods; Solid waste that has no value should be disposed of as a final off. The final disposal methods include incineration, landfill, marine disposal, etc. Solid waste should be detoxified before being landfilled and disposed of in the ocean.
Disposal of semi-solid waste:
The worker drives the forklift into the waste warehouse to complete the loading process, and lifts the semi-solid waste stored in the ton bag, iron tong and iron box and transports it to the packing box of the transport vehicle. The hazardous waste is transported to a designated location by solid waste, and then the semi-solid waste is lifted and poured directly into the underground hopper by the driver operating a forklift. The bottom conveying pump group in the hopper is energized, and then the conveying pump group is opened, and the semi-solid material in the hopper is continuously added to the dryer through the conveying pipe for drying, and the dryer adopts a single-shaft disc dryer or a double-shaft paddle dryer, and uses low-pressure saturated water vapor to indirectly heat the semi-solid sludge treatment material, so that the water in the sludge treatment evaporates and completes the drying process.
Disposal of Unconventional Solid Waste:
According to the characteristics of the garbage, the preparation treatment method is reasonably selected, such as crushing, screening, grinding, etc. According to the nature of the composition, physical, chemical or biological methods are selected for treatment, so as to achieve zero growth and resource utilization of waste. For wastes with radiation or other special pollution, special disposal should be done to ensure safety and harmlessness.
