How to utilize the slag in the garbage dump

With the acceleration of urbanization, the problem of garbage is becoming increasingly prominent. In the process of garbage treatment, slag is a common type of garbage. Slag refers to the solid waste left after burning garbage, which, if not properly treated, can cause serious pollution to the environment. However, if properly utilized, slag can also become a valuable resource. This article will introduce the utilization methods of slag from garbage disposal sites.

1、 Composition and properties of slag

Slag refers to the residual solid waste after Incineration. Its composition and nature are related to the type of garbage, combustion temperature, combustion time and other factors. Generally speaking, the main components of slag are inorganic substances, including oxides, silicates, carbonates, etc. The properties of slag mainly include the following aspects:

1. High temperature: Slag forms at high temperatures and has high thermal stability.

2. High hardness: Slag has a high hardness and can be used to manufacture building materials.

3. High corrosion resistance: Slag has high corrosion resistance and can be used to manufacture corrosion-resistant materials.

2、 Utilization method of slag

1. Manufacturing building materials

Slag can be used to manufacture building materials such as cement, concrete, etc. Mixing slag with an appropriate amount of cement, mortar, and other materials can be processed, formed, and maintained to produce various building materials. These materials have the characteristics of high hardness, good corrosion resistance, and high temperature resistance, and can be used for construction of high-rise buildings, bridges, tunnels, and other projects.

2. Manufacturing corrosion-resistant materials

Slag has high corrosion resistance and can be used to manufacture corrosion-resistant materials. By mixing slag with an appropriate amount of resin, fiberglass, etc., and undergoing processes such as processing, forming, and curing, various corrosion-resistant materials can be made. These materials have characteristics such as acid and alkali resistance, corrosion resistance, and wear resistance, and can be used for manufacturing chemical equipment, marine equipment, etc.

3. Manufacturing road base materials

slag can be used to manufacture road base materials. Mixing slag with an appropriate amount of sand, stone, and other materials can be processed, formed, and maintained to produce road base materials. These materials have the characteristics of high hardness and good durability, and can be used for road construction.

4. Manufacturing environmentally friendly bricks

Slag can be used to manufacture environmentally friendly bricks. By mixing slag with an appropriate amount of cement, stone powder, etc., and undergoing processes such as processing, forming, and curing, environmentally friendly bricks can be made. These bricks have the characteristics of environmental protection, durability, sound insulation, etc., and can be used for building public facilities, residential buildings, etc.

3、 Precautions for slag utilization

1. The slag must be treated before it can be utilized. The processing methods include screening, washing, grinding, etc.

2. The utilization of slag should consider environmental factors. During the utilization process, attention should be paid to reducing the discharge of pollutants and protecting the environment.

3. The utilization of slag should consider economic benefits. In the process of utilization, it is necessary to fully utilize its resource value and achieve maximum utilization of resources.

IV. Conclusion

Landfill slag is a common type of waste that, if not properly treated, can cause serious pollution to the environment. However, if properly utilized, slag can also become a valuable resource. The utilization methods of slag include manufacturing building materials, manufacturing corrosion-resistant materials, manufacturing road base materials, and manufacturing environmentally friendly bricks. During the utilization process, attention should be paid to environmental factors and economic benefits.
