The advantages of comprehensive management and reuse of landfill waste treatment projects mainly include the following aspects:
By reducing the amount of garbage, land resources can be obtained and garbage can be reused. In the process of comprehensive garbage management, garbage can be reduced in capacity, while landfills achieve ecological restoration, allowing the original land to be redeveloped. With the increasing scarcity of land resources, there is a huge market potential for the treatment of stale garbage that has been sealed off and buried.
2. Harmless disposal of garbage can eliminate the pollution of landfill to the surrounding environment and groundwater, especially the large number of informal landfill sites generated due to ineffective protection measures during operation. The water vapor, odor and other pollution emitted by them not only seriously affect the lives of surrounding residents, but also endanger groundwater. The system effectively eliminates the original sources of pollution, improves the ecological environment, and achieves significant environmental and social benefits through the comprehensive management of waste disposal equipment.
3. Garbage resource utilization: After the equipment for garbage treatment is reused, recyclable resources can be obtained, achieving the recycling of resources. Through comprehensive utilization and resource utilization processes, a large amount of humus soil can be obtained, which can be used as cultivation soil for greening flowers and trees, covering soil required for burying soil layers, and biological filtration and purification substrates; If the resource rich and aged landfill resources can be used to replace the above materials, it will have unparalleled advantages in terms of economic and environmental benefits.
4. By using unique and efficient screening techniques and equipment, the aged garbage can be processed. The garbage can be classified according to the material utilization category. The classified combustibles can be used for combustion to generate electricity, humus can be used to cultivate urban landscape vegetation, brick and tile waste can be used for making bricks, and the remaining 5% of unusable materials are finally buried. After processing, the harmless rate of aged garbage has reached 100%, the reduction rate has reached over 95%, the reuse rate has reached 95%, and the resource utilization rate has reached over 90%.
The implementation of this project has multiple practical significance: controlling the uncontrolled diffusion of harmful gases, improving the living environment of surrounding residents, eliminating safety hazards caused by landfill gas, and ensuring the safety of garbage disposal sites and nearby residents; Eliminate the white pollution caused by scattered garbage to the surrounding areas; Restrict atmospheric precipitation from entering garbage disposal sites; Reduce the generation of leachate from garbage.
Classify and recycle garbage to make it a raw material for other production and daily life products, thereby achieving the reuse of garbage. Regeneration, optimization, and development of new production processes, such as using new types of aged waste treatment equipment, dry cement production lines, or other industrial kilns to burn high calorific value household waste as fuel, fully utilizing its calorific value. Emerging industries such as waste incineration power generation treat waste while reducing energy consumption such as coal.
