Methods of wastewater treatment

With the development of urbanization, industrial enterprises, and the increase in wastewater discharge, what are the methods of wastewater treatment? Guangxi Sewage Treatment - Senge Technology and Let's Talk About the Main Methods of Wastewater Treatment?

Due to the rapid development of industry, it has brought about economic growth and reduced the quality of air and water resources. In order to alleviate this situation, it is necessary to carry out wastewater treatment, mainly including the treatment of industrial wastewater and domestic wastewater.

The common method of wastewater treatment is to treat the water quality separately. Today, taking industrial wastewater treatment methods as an example, let me briefly introduce them.

When treating industrial wastewater, it can be divided into three methods based on their principles of action: physical, chemical, and biological

1. Physical processing method

Mainly utilizing physical processes to separate insoluble substances in wastewater, without changing chemical properties during the treatment process. Among them, physical processing mainly uses mechanical equipment. Commonly used methods include gravity separation, centrifugal separation, reverse osmosis, air flotation, etc.

This method has a relatively simple structure and is relatively inexpensive among the three, usually involving precipitation filtration, heat exchange, and combustion.

2. Chemical treatment method

Most wastewater is treated using chemical methods, which add chemicals to the wastewater to react with pollutants, producing substances or colloids that are harmless to human health and nature, thereby removing impurities from the water. The commonly used chemical treatment methods currently include coagulation, neutralization, oxidation-reduction, ion exchange, etc.

The commonly added chemicals include acid-base agents, chlorine, ozone treatment, coagulation precipitation, etc. Good chemical treatment effect and high cost. It is often used as effluent after biochemical treatment for further treatment and improvement of effluent quality.

3. Biological treatment method

Biological treatment is a commonly used method for treating industrial wastewater, usually used as pretreatment. It utilizes the metabolic function of microorganisms to decompose and oxidize dissolved or colloidal organic matter into stable inorganic substances, purifying wastewater.

Utilize biological decomposition of organic matter and impurities in water to make them harmless and pollution-free simple compounds. When using this method to treat wastewater, various treatment units are often combined to achieve effective treatment.

Summary of Guangxi Sewage Treatment - Senge Technology: Utilizing biological decomposition of organic matter and impurities in water to make them harmless and pollution-free simple compounds. When using this method to treat wastewater, various treatment units are often combined to achieve effective treatment.
