Treatment of Incineration fly ash and slag

Treatment of Incineration fly ash and slag

With the acceleration of urbanization, garbage disposal has become an important issue. The traditional landfill method can no longer meet the needs of modern cities, so Incineration has become a common treatment method. However, Incineration will produce a large amount of fly ash and slag, and the treatment of these wastes has also become a problem. This article will introduce the treatment method of Incineration fly ash slag, hoping to provide some help for you.

1、 Treatment of Incineration fly ash

Incineration will produce a large amount of fly ash, which contains a large amount of heavy metals and harmful substances. If not treated, it will cause great harm to the environment and human health. Therefore, the treatment of Incineration fly ash is very important.

1. Stabilization treatment

Stabilization treatment is a common method for Incineration fly ash treatment. This method mixes fly ash with an appropriate amount of cement, lime, and other materials to solidify it into hard lumps. This treatment method can effectively reduce the release of harmful substances in fly ash and reduce environmental pollution.

2. Pyrolysis treatment

Pyrolysis is a method of decomposing Incineration fly ash at high temperature. This method can decompose harmful substances in fly ash through pyrolysis, reducing environmental pollution. At the same time, pyrolysis treatment can also decompose the organic matter in fly ash, generating renewable energy.

3. Crushing treatment

Crushing treatment is a method of mechanically crushing Incineration fly ash. This method can decompose fly ash into small particles for subsequent treatment and utilization. At the same time, crushing treatment can also disperse harmful substances in fly ash, reducing its pollution to the environment.

2、 Treatment of Incineration slag

Incineration slag refers to the solid waste generated in the process of Incineration. This waste contains a large amount of harmful substances such as organic matter and heavy metals. If not treated, it will cause great harm to the environment and human health. Therefore, the treatment of Incineration slag is also very important.

1. Stabilization treatment

Stabilization treatment is a method of mixing Incineration slag with appropriate cement, lime and other materials to solidify them into hard blocks. This method can effectively reduce the release of harmful substances in slag and reduce environmental pollution.

2. Phosphoric acid treatment

phosphoric acid treatment is a method of reacting Incineration slag with phosphoric acid to form compounds such as Aluminium phosphate calcium. This method can convert harmful substances in slag into harmless compounds, reducing environmental pollution.

3. Crushing treatment

crushing treatment is a method of mechanical crushing of Incineration slag. This method can decompose the slag into small particles, which is convenient for subsequent treatment and utilization. At the same time, crushing treatment can also disperse harmful substances in the slag, reducing its pollution to the environment.

3、 Conclusion

The treatment of Incineration fly ash and slag is a complex problem, which requires a variety of methods. This article introduces various methods such as stabilization treatment, pyrolysis treatment, phosphoric acid treatment, and crushing treatment, hoping to provide you with some help. At the same time, we also call on local governments and enterprises to strengthen Waste sorting and recycling, reduce the amount of Incineration, and protect our environment and health.
