With the acceleration of urbanization, the amount of urban waste is also constantly increasing. Incineration is a common treatment method, but the slag after incineration has become a problem. The slag after Incineration contains a lot of heavy metals and harmful substances, which will pose a great threat to the environment and human health if not properly treated. Then, how to deal with the slag after Incineration?

1、 Landfill treatment

Landfill is a traditional waste treatment method, and also a way of slag treatment after Incineration. The principle of landfill treatment is to bury the slag after Incineration in the ground to allow its natural degradation. The advantages of landfill treatment are low cost and simple operation, but there are also some drawbacks. Firstly, landfill treatment will occupy a large amount of land resources and have a certain impact on the environment. Secondly, landfill treatment can not completely eliminate harmful substances in the slag after Incineration, which will pollute groundwater and soil.

The slag after Incineration contains a lot of metal elements, such as iron, aluminum, copper, etc. These metal elements can be reused through recycling. There are various methods for recycling, including magnetic separation, screening, gravity separation, etc. The advantage of recycling is that it can reduce resource waste and environmental pollution, but there are also some difficulties. Firstly, recycling requires a significant investment of manpower, material resources, and financial resources, resulting in high costs. Secondly, the technical requirements for recycling are high, requiring professional equipment and technical personnel.

3、 Curing treatment

垃圾焚烧后的炉渣怎么处理 Solidification treatment is a treatment method to solidify the slag after Incineration into hard objects. The principle of solidification treatment is to mix slag with a certain proportion of cement, lime, and other solidification materials to form a hard block. The advantage of solidification treatment is that it can effectively reduce the volume of slag, reduce the impact on the environment, and also effectively solidify harmful substances in slag, reducing the impact on the environment and human health. However, there are also some drawbacks to solidification treatment, such as the difficulty in reusing the solidified slag and the high cost of solidification treatment.

To sum up, there are many slag treatment methods after Incineration, and each method has its advantages and disadvantages. When selecting the specific treatment method, it is necessary to comprehensively consider the actual situation and choose the most suitable treatment method. At the same time, it is necessary to strengthen the supervision of the slag after Incineration to ensure that it is properly treated and protect the environment and human health.
