There are various methods to treat salty organic wastewater, and the appropriate process can be selected according to the specific characteristics and treatment requirements of wastewater.
The common treatment method is physicochemical treatment. In the process of physical and chemical treatment, salt precipitation, bipolar electrical reaction, ion exchange and other methods can be used to remove salt and organic matter in wastewater. The principle of bipolar electrical reaction can also be used to break down wastewater into more treatable substances, or ion exchange resins can be used to remove salts from wastewater.
Biological treatment is also a common method for treating saline organic wastewater. By using microorganisms to break down organic matter in wastewater, the salt concentration in wastewater is reduced. Biological treatment requires the establishment of a suitable microbial population that can thrive under suitable environmental conditions and can effectively degrade organic matter in wastewater.
In addition, there are other treatment methods available, such as membrane separation, evaporation crystallization, etc. Membrane separation is to separate the salts and organic matter in the wastewater through the selective permeability of the membrane to achieve wastewater purification. Evaporation crystallization is through the evaporation of water in the wastewater, so that the content of salt and organic matter has been greatly increased, which is convenient for better follow-up treatment or utilization.
