Slag treatment for domestic Incineration power generation

Slag treatment for domestic Incineration power generation

With the acceleration of urbanization, the amount of urban garbage is also constantly increasing, and garbage treatment has become an urgent problem to be solved. Incineration power generation technology has been used for garbage treatment in China to a certain extent, but it also produces a large number of slag. How to handle these slag has become a new problem.

I. Characteristics of slag for domestic Incineration power generation

Domestic Incineration power generation slag is mainly composed of iron, aluminum, glass, ceramics and other inorganic substances, which contains a large number of heavy metal elements, such as lead, cadmium, mercury, etc., which are very harmful to the environment and human health.

2、 Domestic slag treatment method for Incineration power generation

1. Landfill method

Landfill is one of the main methods for the treatment of Incineration power generation slag in China at present. Transport the slag to a landfill and fill it together with other waste. However, there are some problems with the landfill method, such as occupying land resources and making it difficult to control pollution.

2. Recycling

Recycling is a relatively ideal treatment method. The slag contains a large amount of iron, aluminum, glass and other substances, which can be recycled for secondary use. If metals such as iron and aluminum in the slag are recycled, it can reduce the consumption of natural resources and also bring certain economic benefits.

3. Chemical curing

Chemical solidification is a method of converting harmful substances in slag into harmless substances. By adding chemical curing agents, the heavy metal elements in the slag are converted into insoluble compounds, thereby achieving the goal of solidification. This method can effectively reduce the content of heavy metal elements in slag and reduce environmental pollution.

3、 Development Trend of Slag Treatment for Incineration Power Generation in China

At present, there are still some problems in the slag treatment technology of Incineration power generation in China, such as high treatment cost, unstable treatment effect, etc. In the future, the slag treatment technology for Incineration power generation in China will develop towards the direction of low cost, high efficiency and environmental protection. At the same time, recycling will become one of the main directions of Incineration power generation slag treatment.

IV. Conclusion

The slag treatment of Incineration power generation in China is an urgent problem, which needs to be solved reasonably. Landfill, recycling, and chemical solidification are currently the main treatment methods. In the future, the slag treatment technology for Incineration power generation will be developed in the direction of low cost, high efficiency and environmental protection.
