The significance and required equipment of landfill waste reprocessing

The screening treatment of landfill sites is of great significance for environmental protection, resource recycling and utilization, and land protection. By separating recyclable components, preventing environmental pollution, and controlling greenhouse gas emissions, the efficiency and economic benefits of waste treatment have been improved. Corresponding equipment such as screening equipment, crushing equipment, sorting equipment, etc. also play a crucial role. Garbage screening and treatment is a necessary measure to achieve the goals of waste reduction, resource utilization, and harmless treatment, which is in line with modern environmental protection concepts and sustainable development requirements.

The screening and treatment of landfill waste has multiple important meanings, mainly including the following aspects:

1. Resource recycling and utilization:

Screening treatment can effectively separate recyclable components such as metals, plastics, glass, paper, etc. from garbage. These materials can be reused in the production cycle, reducing the demand for new raw materials and promoting the development of circular economy.

2. Environmental protection:

Reducing environmental pollution: Screening can separate harmful waste, such as waste batteries, chemicals, fluorescent tubes, etc., to prevent soil and groundwater pollution caused by their leakage.

Control greenhouse gas emissions: Through aerobic pretreatment, landfill gas (mainly composed of methane) can be released and collected for energy utilization, reducing greenhouse gas emissions.

3. Land resource protection:

Through screening treatment, the volume of garbage is significantly reduced, thus reducing the land area of the landfill site, which is conducive to the rational allocation and conservation of land resources.

For saturated landfill sites, after excavating and screening aged waste, the site can be repaired and reused, such as for green spaces, parks, or other construction land.

4. Improve processing efficiency and economic benefits:

The automation and mechanization of garbage screening and treatment equipment greatly improves the efficiency of garbage treatment, reduces labor costs, and also enhances the economic benefits of the garbage treatment industry.

The sorted combustibles can be used for incineration and power generation, which not only solves the problem of garbage disposal but also generates electricity, generating certain economic benefits.

5. Meet environmental policy requirements:

With the increasingly strict environmental regulations, the requirements for waste treatment are also increasing. The screening and treatment of landfill waste can help achieve the goals of waste reduction, resource utilization, and harmless treatment, which is in line with modern environmental protection concepts and sustainable development strategies.

In summary, the screening and treatment of landfill waste is of great significance for improving the overall level of waste management, promoting green economic development, and improving the ecological environment.

The screening and treatment of stale garbage is a complex process that involves multiple links and equipment.Here are some main equipment:

1. Screening equipment:

Roller screen: used to screen raw materials below 40mm, mainly organic chemical soil.

Star screen: Screening organic chemical soil below 50mm, suitable for landscape garden afforestation.

Vibration screen: used to screen materials such as stones with a diameter of over 40mm.

Mouse cage screening: Select materials with a size of 200mm or more.

Air separation equipment: Separate the light and heavy materials from the 40-200mm raw materials. The heavy materials can be used for on-site backfilling of raw waste, while the light materials are transported to the sorting equipment for further sorting.

2. Crushing equipment:

Cutting crushers, blade crushers, jaw crushers, etc.: used to crush aged garbage into smaller or specified sized particles for subsequent sorting and treatment.

3. Sorting equipment:

Magnetic separator: used to separate useful metal materials, especially iron.

Equipment such as sorting machines, electrostatic generators, industrial exhaust fans, etc.: Classify waste plastics and dirt.

4. Transmission equipment:

Scale feeder, belt conveyor, chain plate conveyor, etc.: used for material transportation during garbage feeding and sorting processes, as well as process connection of key equipment.

5. Packaging equipment:

Fully automatic packaging machine: used for packaging waste plastics.

In addition, the screening and treatment of stale waste may also involve other auxiliary equipment, such as dust removal equipment, noise reduction equipment, etc., to ensure the environmental protection and safety of the treatment process.

Please note that the specific equipment configuration and selection should be determined based on the composition of aged waste, treatment scale, treatment requirements, as well as local environmental and economic conditions. Therefore, in practical operation, it is recommended to consult professional waste treatment equipment suppliers or relevant institutions to obtain more specific and personalized solutions.
