Garbage slag refers to the solid residue produced in the process of Incineration, which contains a lot of inorganic salts and heavy metals, causing great pollution to the environment. However, waste slag is also a valuable resource that can be comprehensively utilized to reduce its impact on the environment. This article will introduce the comprehensive utilization methods and operational steps of waste slag.
1、 Comprehensive utilization methods of garbage and slag
1. Cement production
Garbage slag contains a large amount of substances such as silicate and alumina, which can be used as raw materials for cement production. A new type of cement material can be obtained by mixing waste slag with limestone, coal ash, and other materials and conducting high-temperature calcination. This cement material can not only replace some traditional cement materials, but also reduce production costs and reduce environmental pollution.
2. Roadbed construction
Garbage slag contains a large amount of inorganic salts and heavy metals, which can be used as materials for roadbed construction. A new type of roadbed material can be obtained by mixing waste slag with sand, stone, and other materials and processing them into shape. This type of roadbed material can not only reduce the demand for traditional roadbed materials, but also reduce environmental pollution.
3. Cover layer of solid waste landfill site
Garbage slag contains a large amount of inorganic salts and heavy metals, which can be used as a material for the covering layer of solid waste landfills. Laying waste slag on the surface of a solid waste landfill can effectively prevent waste leakage and odor diffusion, while also reducing the area and cost of the landfill.
2、 Operational steps for comprehensive utilization of garbage and slag
1. Cement production
(1) Mix waste slag, limestone, coal ash and other raw materials in a certain proportion.
(2) Send the mixed raw materials into a rotary kiln for high-temperature calcination.
(3) Send the calcined material into the cooler for cooling.
(4) After the cooled material is processed through processes such as crushing and screening, a new type of cement material can be obtained.
2. Roadbed construction
(1) Mix garbage, slag, sand, stone and other raw materials in a certain proportion.
(2) Feed the mixed raw materials into the processing equipment for molding.
(3) Transport the formed roadbed materials to the site and lay them.
3. Cover layer of solid waste landfill site
(1) Transport waste and slag to the landfill site.
(2) Lay the waste slag on the surface of the landfill and compact it.
(3) Cover the laid waste slag with a layer of soil and compact it.
3、 Conclusion
Garbage slag is a valuable resource that can be comprehensively utilized to reduce its impact on the environment. This article introduces the comprehensive utilization methods and operational steps of waste slag, including cement production, roadbed construction, and solid waste landfill cover. These utilization methods can not only reduce the demand for traditional resources, but also reduce production costs and reduce environmental pollution.
