Solvent extraction method and treatment of wastewater containing phenol

by:Deyuan      2020-08-17
Over the years, researchers from all over the world and developed a variety of high concentration organic wastewater treatment, such as the biological oxidation method, adsorption method, chemical oxygen, steam formulation, evaporation method, solvent extraction, etc. The solvent extraction method not only has the advantages of low equipment investment, cover an area of an area small, simple operation, low energy consumption, has the advantages of rich experience of industrial operation, and the main pollutants effectively recycling, so the solvent extraction method is widely used in various kinds of organic wastewater treatment, solvent extraction are the main disadvantages of solvent loss and thus cause secondary pollution, solvent extraction method is suitable for recycle and treatment of high concentration of refractory organic industrial wastewater and separation with high solute distribution coefficient of the system, such as phenol contained wastewater, organic wastewater containing phosphorus, nitrogen, organic sulfonic acid wastewater, organic carboxylic acid waste water etc.
