Utilization technology of domestic Incineration slag

With the acceleration of urbanization, the amount of household waste is also constantly increasing. According to statistics, the total amount of domestic waste in China has exceeded 200 million tons per year, most of which is incinerated. However, the slag generated by incineration of household waste has become a challenge. The traditional method of slag treatment is landfill, but landfill can cause serious environmental pollution. Therefore, the utilization technology of domestic Incineration slag came into being.

The utilization technology of domestic Incineration slag refers to the resource utilization of the incinerated domestic waste slag to turn waste into treasure. This technology can effectively reduce environmental pollution and also provide new economic growth points for society. Next, we will introduce the operation steps of the domestic Incineration slag utilization technology in detail.

I. Slag sorting

The first step in the utilization technology of domestic Incineration slag is to separate the slag. Slag sorting refers to the sorting of incinerated household waste slag into different categories based on different physical and chemical characteristics. Generally speaking, household waste slag can be divided into several types, including brick slag, glass slag, heavy metal slag, and harmless slag.

2、 Slag treatment

After the slag sorting, the slag treatment can be carried out. Slag treatment refers to the further processing of the sorted slag to achieve usable standards. Generally speaking, slag treatment can be carried out through various methods such as physics, chemistry, biology, etc. Among them, physical processing is the most common method, including grinding, screening, magnetic separation, etc.

3、 Slag utilization

After the slag treatment is completed, the slag can be utilized. The slag utilization of domestic Incineration slag utilization technology can be divided into several aspects, including building materials, cement production, road laying, etc. Among them, building materials are one of the main directions for slag utilization. Slag can be used to make building materials such as bricks, wall panels, and floor tiles, which have excellent fire resistance and waterproof properties and are widely used in fields such as construction, metallurgy, and chemical engineering.

In a word, the utilization technology of domestic Incineration slag is a very promising technology, which can effectively reduce the environmental pollution and provide new economic growth points for the society. In the future, we believe that the utilization technology of domestic Incineration slag will be more widely used.
