Waste and slag recovery technology

With the continuous development of urbanization, the problem of garbage is becoming increasingly serious. Garbage treatment has always been a challenge, and the treatment of garbage and slag is even more challenging. However, with the continuous development of technology, the recycling technology of garbage and slag has also made great progress. This article will introduce you to the technology and operating steps of garbage and slag recovery.

Overview of garbage and slag recovery technology

Garbage slag refers to the solid waste generated during Incineration. The recycling and utilization of garbage and slag has always been a challenge, as the composition of garbage and slag is complex, containing a large amount of harmful substances such as heavy metals and hazardous chemicals, which pose certain risks to the environment and human health. However, with the continuous development of technology, the recycling and utilization of garbage and slag have also made great progress.

At present, the recycling and utilization of garbage and slag mainly includes the following technologies:

1. Cement products: After mixing waste slag with raw materials such as cement and lime, they are sintered at high temperatures to produce cement products, such as cement bricks and cement pipes.

2. Roadbed material: After mixing garbage and slag with raw materials such as sand and gravel, it is made into roadbed material and used for highway construction.

3. Landfill cover layer: Lay waste slag on the landfill site to cover the waste and reduce the area of the landfill.

4. Other uses: Waste slag can also be used to manufacture building materials such as cement, ceramics, bricks, and industrial materials such as ceramics and glass.

2、 Operation steps of garbage and slag recovery technology

The operational steps of garbage and slag recovery technology mainly include the following aspects:

1. Collection and classification of garbage and slag: The recycling and utilization of garbage and slag requires the collection and classification of garbage first, separating recyclable garbage and slag from other garbage for subsequent treatment.

2. Treatment of garbage and slag: The treatment of garbage and slag mainly includes two methods: physical treatment and chemical treatment. Physical treatment includes methods such as screening, magnetic separation, and gravity separation, while chemical treatment includes methods such as acid washing, alkali washing, and soaking.

3. Recycling and utilization of garbage and slag: The recycling and utilization of garbage and slag mainly includes various methods such as cement products, roadbed materials, landfill cover, etc. The specific selection needs to be comprehensively considered based on factors such as the composition and use of garbage and slag.

4. Monitoring and evaluation of garbage and slag: The recycling and utilization of garbage and slag need to be monitored and evaluated to ensure that there is no harm to the environment and human health during the recycling process.

3、 Conclusion

The development of waste slag recycling technology provides new ideas and methods for waste treatment. By recycling and utilizing garbage and slag, not only can the amount of garbage treatment be reduced, but also the pollution to the environment can be reduced, and economic benefits can be brought to society. However, the recycling and utilization of waste slag also faces some challenges, such as the complex composition of waste slag and the immature recycling technology. Therefore, while promoting garbage and slag recycling technology, it is also necessary to continuously innovate and improve technology to achieve maximum recycling and environmental protection of garbage and slag.
