Industrial waste refers to all kinds of waste generated by industrial production, including solid waste, liquid waste and gaseous waste. These wastes will cause great harm to the environment and human health, and it is very necessary for the treatment and treatment of industrial waste. The emergence of industrial waste sorting technology provides a more efficient and environmentally friendly solution for the treatment of industrial waste.
First, the significance of industrial waste sorting.
Industrial waste sorting technology is the use of advanced sorting equipment to classify and separate industrial waste, the best and available waste for reuse, and at the same time the hazardous waste for special treatment, in order to reduce pollution and save resources. The emergence of this technology can not only effectively reduce environmental pressure, but also save costs and improve economic benefits for enterprises.
Second, the classification of industrial waste sorting.
According to the different characteristics and treatment requirements of industrial waste, industrial waste sorting technology can be divided into the following categories:
1.Solid waste sorting.
2.Liquid waste sorting.
3.Gaseous waste sorting.
3. Solid waste sorting technology.
Solid waste is the most important component of industrial waste, so the sorting technology of solid waste is also the most mature and widely used. Solid waste sorting technology mainly includes mechanical sorting, gravity sorting, magnetic sorting, optical sorting and other methods.
1.Mechanical sorting.
Mechanical sorting is a method of screening and separating solid waste by using equipment such as vibrating screens and air flow separators. This method is suitable for situations where the waste particles are large and the density difference is large.
2.Gravity sorting.
Gravity separation is a method that uses the density difference of waste particles to separate. This method is suitable for situations where there is a large difference in waste density.
3.Magnetic sorting.
Magnetic separation is a method of separating ferromagnetic materials using the difference in waste. This method is suitable for cases where the waste contains ferromagnetic substances.
4.Optical sorting.
Optical sorting is a method of separating waste species using characteristics such as color and shape. This method is suitable for situations where the color and shape of the waste species vary greatly.
4. Liquid waste sorting technology.
Liquid waste refers to all kinds of liquid waste, waste oil and other liquid wastes generated in the industrial production process. Liquid waste sorting technology mainly includes physical separation, chemical separation and biological separation.
1.Physical sorting.
Physical separation is a method of separating liquid waste by physical methods. This method is suitable for situations where liquid waste contains suspended solids and sediments.
2.Chemical sorting.
Chemical separation is a method of separating liquid waste by chemical methods. This method is suitable for liquid waste containing hazardous substances such as heavy metals and organic matter.
3.Biological sorting.
Biosorting is a method of separating liquid waste using biotechnology. This method is suitable for cases where liquid waste contains biodegradable substances.
5. Gas waste sorting technology.
Gaseous waste refers to all kinds of waste gases generated in industrial production processes. Gas waste sorting technology mainly includes physical separation and chemical separation methods.
1.Physical sorting.
Physical separation is a method of separating exhaust gas by physical methods. This method is suitable for situations where the exhaust gas contains particulate matter, soot, etc.
2.Chemical sorting.
Chemical separation is a method of separating exhaust gas by chemical methods. This method is suitable for situations where the exhaust gas contains harmful gases.
The emergence of industrial waste sorting technology provides a more efficient and environmentally friendly solution for the treatment of industrial waste. With the continuous development of technology, industrial waste sorting technology will also be continuously improved and improved, and make greater contributions to the cause of environmental protection.
