The treatment of household waste has always been a challenge in urban management, as the amount of household waste is increasing and the treatment methods are constantly being updated. Incineration power generation is a common treatment method, which can turn domestic Incineration into electric energy, but the slag treatment after incineration is also a problem. This article will introduce in detail the operation steps of slag treatment for domestic Incineration power generation, as well as the relevant knowledge of slag treatment.
I. Composition of domestic Incineration power generation slag
After incineration of household waste, the generated slag is mainly composed of inorganic substances and some organic substances. Inorganic matter mainly includes minerals, glass, metals, etc., while organic matter includes incomplete incineration of organic matter and burned ash. Among them, the content of organic matter is relatively low, mainly due to incomplete incineration of organic matter, so the main component of slag is inorganic matter.
2、 Treatment of slag from domestic Incineration power generation
1. Classification of slag
Different treatments are required depending on the composition of the slag. Generally speaking, slag can be divided into four types: metal slag, glass slag, slag, and ash. Metal slag can be recycled, glass slag can be used to make glass products, slag can be used as building materials, and ash needs to be landfilled.
2. Recycling and utilization of slag
Metal slag can be recycled and reused, mainly through magnetic separation and gravity separation. Magnetic separation mainly utilizes different magnetic substances to separate metals from metal slag. Gravity separation is the use of different substances with different densities to separate metals from metal slag. Recycling metal slag can not only reduce environmental pollution, but also save resources.
3. Landfill treatment of slag
Ash and slag are inorganic substances contained in furnace slag, and their main treatment method is landfill. Landfill treatment requires selecting a suitable site, covering the site with ash, then compacting it, and finally covering it. It should be noted that the landfill site should be located in a sparsely traveled area to avoid pollution to the surrounding environment.
3、 Significance of slag treatment for domestic Incineration power generation
The significance of slag treatment for domestic Incineration power generation is that it can transform domestic waste into renewable energy and reduce dependence on traditional energy. At the same time, the treatment of slag is also an important part of environmental protection. By treating slag, it can reduce environmental pollution and protect the ecological environment.
The treatment of household waste is a complex process, and the treatment of incineration and power generation slag is also an important link. The treatment of slag needs to be classified according to different components, and then appropriate treatment methods should be selected for treatment. The treatment of household waste is not only a difficulty in urban management, but also an important part of environmental protection. We need to work together to protect our environment and create a better future.Slag treatment of domestic Incineration power generation
