Incineration slag refers to the solid waste generated in the process of Incineration, which contains a large number of organic, inorganic, heavy metals and other harmful substances. If not treated, these Incineration slag will cause great harm to the environment and human health. So, how to deal with Incineration slag?
1、 Hazards of Incineration slag
Incineration slag contains a large number of organic, inorganic and heavy metals and other harmful substances, which are harmful to human health and the environment. First of all, the organic substances in the Incineration slag will produce ozone, carbon monoxide and other harmful gases in the air, which will affect the air quality. Secondly, inorganic substances and heavy metals in Incineration slag will infiltrate into soil and groundwater, causing environmental pollution. Finally, the harmful substances in the Incineration slag will enter the human body through the food chain, posing a threat to human health.
2、 Treatment method of Incineration slag
1. Landfill treatment of incineration slag
Landfill is a common treatment method for Incineration slag. Transport the Incineration slag to the landfill for landfill treatment. Landfill treatment can reduce the environmental pollution caused by Incineration slag, but it will also waste land resources, and the operation and management costs of the landfill are also high.
2. Recycling and utilization of incineration slag
Recycling is a more environmentally friendly and economical method of Incineration slag treatment. There are a lot of inorganic substances and heavy metals in the slag of Incineration, which can be recycled to turn waste into treasure. For example, the metal materials in the Incineration slag can be recycled, and the minerals in the Incineration slag can also be used for the production of building materials.
3. Chemical treatment of incineration slag
Chemical treatment is an effective method for Incineration slag treatment. Through chemical treatment, the harmful substances in Incineration slag can be separated and transformed to reduce environmental pollution. For example, heavy metals in Incineration slag can be chemically reduced, and organic substances can be pyrolyzed and oxidized.
3、 Conclusion
The treatment of Incineration slag is an important environmental protection work. Only adopting scientific and effective treatment methods can reduce the harm of Incineration slag to the environment and human health. Landfill treatment, recycling and chemical treatment are three common Incineration slag treatment methods, and appropriate treatment methods need to be selected according to the specific situation. At the same time, we should also reduce the generation of garbage from the source, improve the recycling rate of garbage, and jointly contribute to building a beautiful China.
