The technology of green waste landfill covers many fields, including mechanical engineering, environmental science, chemical engineering, etc. Here are some of the key technologies and their applications:

1. Crushing technology: used to break large pieces of garbage into smaller particles. This is usually achieved through crushers, such as jaw crushers, hammer crushers and shear crushers.

2. Sorting technology: It is used to separate different components in the waste (such as metal, plastic, paper, organic matter, etc.). This can be achieved by magnetic separation, wind separation, flotation, screening and other methods.

3. Biological treatment technology: for the treatment of organic waste, such as kitchen waste and garden waste. This includes processes such as anaerobic digestion, composting and aerobic fermentation, which can turn organic waste into fertilizer or biogas.

4. Incineration technology: It is used to burn waste to reduce its volume and recover energy. Modern incineration equipment is equipped with efficient flue gas purification systems to reduce emissions of pollutants.

5. Physical and chemical treatment technology: used to deal with special types of waste, such as electronic waste, hazardous waste, etc. This may include processes such as chemical neutralization, precipitation, adsorption, and ion exchange.

6. Compression technology: used to reduce the volume of waste, improve the efficiency of transportation and treatment. This is usually achieved by compression balers and compression cars.

7. Monitoring and control technology: It is used to monitor the key parameters in the waste treatment process in real time, such as temperature, pressure, flue gas composition, etc., and adjust it through the automatic control system.

8. Energy recovery technology: used to recover energy from the waste disposal process. For example, the heat generated by incineration can be used for electricity generation or heating, while biogas produced by biological processing can be used as fuel.

9. Waste water and waste gas treatment technology: used to treat the waste water and waste gas generated during the waste treatment process to ensure that it meets the discharge standards. This may include sedimentation tanks, biofilters, activated carbon adsorption towers and other devices.

10. Noise reduction and dust prevention technology: used to reduce the noise and dust generated by green waste landfill operation. This includes soundproofing materials, dust collection systems and spray dust removal devices.

Technological advances at green waste landfill are designed to improve treatment efficiency, reduce environmental pollution and maximize the recovery of resources. As technology continues to evolve, green waste landfill is becoming more automated, intelligent and environmentally friendly.
