Reuse of slag from garbage power plants

Reuse of slag from garbage power plants

With the continuous advancement of urbanization, garbage disposal has become an increasingly important issue. The traditional landfill method not only occupies a large area, but also generates a large amount of pollutants, causing great impact on the environment. Therefore, garbage power plants have gradually become a new type of waste treatment method. Not only can it effectively handle garbage, but it can also generate electricity. However, garbage power plants also produce a large amount of slag, which, if not treated, can have a significant impact on the environment. Therefore, the reuse of slag from garbage power plants has become a current hot topic.

1、 Composition and hazards of slag

The slag of garbage power plants refers to the solid waste generated during the garbage power generation process, mainly composed of metal oxides such as iron, aluminum, calcium, magnesium, silicon, and non-metallic oxides. The main harm of slag is that it contains a large amount of heavy metals and organic substances, which have a certain degree of harm to the environment and human body.

II. Recycling methods of slag

1. Brick making with slag

Slag can be used to manufacture bricks, which not only reduces the discharge of slag, but also reduces the consumption of raw materials in the brick production process. The process of making bricks from slag is relatively simple, simply mixing the slag with a certain proportion of water and cement, and then pressing it into shape.

2. Slag making sand

slag can also be used to manufacture sand, which not only reduces the discharge of slag, but also reduces the consumption of raw materials in the sand production process. The process of making sand from slag is relatively simple, which only requires crushing, screening, washing, and other treatments, followed by drying, grinding, and other processes to finally produce sand that meets the requirements.

3. Advantages and disadvantages of slag brick and sand making

The methods of making bricks and sand from slag can effectively utilize slag and reduce slag emissions, but both methods also have some drawbacks. The disadvantage of using slag to make bricks is that their strength and durability are relatively poor, while the disadvantage of using slag to make sand is that its fineness and quality are difficult to control.

Prospect of slag reuse

The reuse of slag from garbage power plants is a very promising approach, which not only effectively reduces the discharge of slag, but also reduces the consumption of raw materials and reduces environmental pollution. In the future, with the continuous progress of technology, the ways of slag reuse will become increasingly diverse, making greater contributions to the environmental protection industry.

In short, the reuse of waste power plant slag is a very important environmental protection measure, which can effectively reduce the discharge of slag and reduce environmental pollution. In the future, we should continue to explore new ways of slag reuse and make greater contributions to the environmental protection industry.
