solvent extraction method is commonly used in industry of coal coking wastewater removing phenol method. Complexation extraction treatment of high concentration phenol wastewater has been applied in phenol, pharmaceutical factory, easy to implement industry, 2 - - Three extraction theory level can reach the discharge standards prescribed by the state. Such as a river using complexation extraction agent is 30% the TBP kerosene solution, and phenol form of 1:1 complex, through the tertiary cross-flow extraction wastewater phenol concentration by 10767 ° mg can be L - 1 to 50 mg ° L - 1 the following, removing phenol rate is higher than 99. 5%. Reversible complexation reaction of removing phenol extraction separation method for step extraction, puts forward the possible routes. Developed by tsinghua university hybrid complexation extraction agent QH - 1, used for industrial treatment of wastewater containing phenol, obtain ideal effect, can be through a single extraction operation make the quantity of waste water containing phenol is lower than the national standard. But this technique for the liquid liquid extraction, after the water need to the oil-water separator to emissions, there is a problem such as solvent loss.
in recent years, zhengzhou DE source extraction using extractant macroporous polymer system with the basic idea of hydrocarbons in water, according to the characteristics of the industrial waste water containing phenol, developed a series of YH type efficient stationary phase complexation extraction agent, has solved the problems such as solvent loss. Yin means lower production costs such as research of stationary phase complexation extraction agent YH - 1, under the condition of acidic and neutral, is applied to single stage or multistage fixed bed ( Or vibration bed) Can remove the wide concentration range of wastewater containing phenol. YH - 1 grain available NaOH solution regeneration, regeneration rate is better than activated carbon, 99. 3%, stationary phase complexation extraction method has a wide scope of operation, easy regeneration, the treatment effect is good wait for a characteristic, is one who has a price competitive advantage, efficient and reliable new technology.


the development trend of solvent extraction (1) Solvent extraction in the stationary phase complexation extraction method has a wide scope of operation, easy regeneration, the treatment effect is good wait for a characteristic, is one who has a price competitive advantage, efficient and reliable new technology.
2) Considering the complexity and diversity of wastewater containing phenol, only with a kind of method is often difficult to achieve expected purpose, so, want to consider the combination of several kinds of technology. Such as the combination oxidation technique as a pretreatment method and biological method, in order to realize the purpose of efficient and economic. This is also in zhengzhou's source extraction technology of refractory organics treatment a research direction.







DE source extraction to recommend using extraction solvent extraction equipment for coal coking wastewater removing phenol help you understand the extraction equipment and production capacity, technological process, characteristics of the equipment, such as detailed specification, at the same time can also see the relevant customer case and extraction equipment solution, the research trend, you can also browse all extraction equipment.
