Comprehensive utilization of waste power generation slag

Comprehensive utilization of waste power generation slag

With the process of urbanization, the problem of garbage is becoming increasingly serious, and garbage treatment has become an important issue in urban management. Garbage power generation is an effective way of garbage disposal, but garbage power generation generates a large amount of slag, and how to utilize these slag has become a new problem. This article will introduce the comprehensive utilization method of waste power generation slag.

1、 Basic situation of slag

Waste power generation slag refers to the solid waste generated in the process of waste power generation. Its main components are aluminum oxide, iron oxide, Calcium oxide, magnesium oxide, etc. The chemical composition and physical properties of slag determine its applicability in various fields.

2、 Comprehensive utilization method of slag

1. Building materials field

Slag can be used to produce building materials such as cement and concrete. Alumina, Calcium oxide and other substances in the slag can be used as raw materials of cement, while iron oxide in the slag can be used as pigment of concrete.

2. Agriculture

Slag can be used to improve soil and enhance soil fertility. The Calcium oxide in the slag can neutralize acidic soil, while the iron oxide in the slag can promote plant growth.

3. Environmental protection field

Slag can be used to treat environmental problems such as sewage and soil pollution. Iron oxide in slag can absorb heavy metal ions, while Calcium oxide in slag can neutralize acidic wastewater.

3、 Specific operating steps for comprehensive utilization of slag

1. Collection and classification of slag

Garbage power generation slag needs to be classified and collected, and different types of slag need to be separated for subsequent utilization.

2. Treatment and processing of slag

The slag needs to be treated and processed for subsequent utilization. The processing and processing methods include crushing, screening, grinding, etc.

3. Utilization of slag

Slag can be used in fields such as building materials, agriculture, and environmental protection. The specific utilization methods include producing cement, concrete, improving soil, and treating sewage.

4、 Advantages of comprehensive utilization of slag

1. Reduce the amount of garbage

The comprehensive utilization of waste power generation slag can reduce the amount of waste and alleviate the pressure of urban waste treatment.

2. Save resources

The comprehensive utilization of slag can save resources and reduce the consumption of natural resources.

3. Protecting the environment

The comprehensive utilization of slag can reduce environmental pollution and protect the ecological environment.

In summary, the comprehensive utilization of waste power generation slag is an effective waste treatment method, which can reduce the amount of waste, save resources, and protect the environment. The comprehensive utilization methods of slag include fields such as building materials, agriculture, and environmental protection, which require classified collection, treatment, and processing. The specific operating steps include crushing, screening, and grinding.
