How to deal with the slag after Incineration

With the continuous acceleration of urbanization, the problem of garbage has gradually become an urgent problem to be solved. In order to solve this problem, Incineration is adopted in many places. Incineration can effectively reduce the volume and weight of garbage, and can burn harmful substances to reduce environmental pollution. However, a large amount of slag will be left after Incineration, which will cause serious environmental pollution if not treated. Then, how to deal with the slag after Incineration?

1、 What is the slag after Incineration

The slag after Incineration refers to the solid waste generated after the garbage is burned at high temperature. These wastes are mainly composed of inorganic substances, such as metal, glass, limestone, etc. The slag after Incineration is usually characterized by high temperature, high corrosivity, high alkalinity, high heavy metal content, etc., which causes serious environmental pollution.

2、 Slag treatment method after Incineration

1. Landfill

Landfill is a relatively traditional slag treatment method after Incineration. The advantages of this method are simple operation and low cost. However, landfill will occupy a large amount of land resources and cause pollution to groundwater.

2. Recycling

The slag after Incineration contains many useful metal and inorganic substances, which can be reused by recycling. For example, metals such as aluminum, iron, and copper in slag can be recycled through methods such as magnetic separation and gravity separation. Inorganic substances such as glass and ceramics in slag can be used to manufacture building materials, road materials, etc.

3. Incineration

There are still some organic substances in the slag after Incineration, which will pollute the environment. In order to thoroughly treat these organic substances, incineration can be used. Incineration can burn off the organic substances in the slag, reducing environmental pollution.

3、 Precautions for slag treatment after Incineration

1. Prevention of secondary pollution

The slag after Incineration has the characteristics of high corrosivity, high alkalinity, high heavy metal content, etc. If it is not treated, it will cause serious environmental pollution. Therefore, attention should be paid to preventing secondary pollution and taking effective measures to protect the environment during the treatment process.

2. Reasonable utilization of resources

The slag after Incineration contains many useful metal and inorganic substances, which can be reused by recycling. Therefore, in the processing process, it is necessary to fully utilize these resources and reduce waste.

3. Safe operation

The slag after Incineration has the characteristics of high temperature, high corrosivity, etc. Pay attention to safety during operation. Operators should wear protective equipment to ensure their own safety.

4、 Summary

The slag after Incineration is a kind of hard to treat solid waste, but through reasonable treatment methods, it can be transformed into useful resources to reduce environmental pollution. During the processing, attention should be paid to preventing secondary pollution, fully utilizing resources, and ensuring safe operation.
