Waste disposal has always been one of the difficult problems in urban management, and Incineration is a common treatment method. However, burning garbage can generate a large amount of slag, which, if left untreated, can cause environmental pollution. This article will introduce the treatment technology of incineration waste slag, including the composition of the slag, treatment methods, and application prospects.
1、 Composition of slag
Slag refers to the solid waste formed after incineration of garbage, which has a complex composition including inorganic and organic substances. Among them, inorganic substances mainly include metal oxides, glass, and ceramics, while organic substances include incompletely burned organic substances and tar.
II. Treatment method of slag
1. Landfill method
The 
landfill method is a traditional waste treatment method and a common slag treatment method. Landfill the slag underground, allowing it to come into contact with the soil and gradually degrade. The advantage of landfill method is its low cost, while the disadvantage is that it occupies land resources and is prone to causing groundwater and soil pollution.
2. Recycling
Recycling is a sustainable slag treatment method that can recycle useful substances from the slag. For example, metal oxides can be used to produce building materials and ceramics, while glass can be used to produce glass products. The advantage of recycling is that it reduces resource waste, while the disadvantage is that it is technically difficult and requires a significant investment of manpower and material resources.
3. Stabilization treatment
Stabilization treatment is a method of stabilizing harmful substances in slag. For example, oxidizing incompletely burned organic matter into harmless carbon dioxide and water. The advantage of stabilization treatment is that it can reduce environmental pollution, but the disadvantage is that a large amount of energy needs to be invested.
3、 Application Prospects
The application prospects of incineration slag treatment technology are broad. With the acceleration of urbanization, the problem of garbage treatment has become increasingly urgent, and slag treatment technology has also received increasing attention. In the future, the treatment technology of incineration waste slag will develop towards environmental protection, energy conservation, and efficiency, becoming an important component of urban waste treatment.
In short, the incineration of waste and slag treatment technology is an important environmental protection technology that can effectively solve the problem of urban waste treatment. There are various methods for treating slag, which need to be selected based on specific circumstances. In the future, slag treatment technology will continue to innovate, providing more sustainable, environmentally friendly, and efficient solutions for urban waste treatment.
