2 - Naphthol is an important organic chemical raw materials and dye intermediates, mainly for the production of dyes and dye intermediates, usually used for textile auxiliaries. And 2 - 2 - naphthol and Naphthol sodium are soluble in water, so, often containing 2 - in the printing and dyeing wastewater Naphthol. Because of the 2 - The particularity of naphthalene phenolics, their environmental impact is the environmental protection department attaches great importance to both at home and abroad, so the 2 - a fast and efficient It is particularly important to naphthalene phenolics processing method.

2- Naphthol is an important organic chemical raw materials and dye intermediates, mainly for the production of dyes and dye intermediates, usually used for textile auxiliaries. And 2 - 2 - naphthol and Naphthol sodium are soluble in water, so, often containing 2 - in the printing and dyeing wastewater Naphthol. Because of the 2 - The particularity of naphthalene phenolics, their environmental impact is the environmental protection department attaches great importance to both at home and abroad, so the 2 - a fast and efficient It is particularly important to naphthalene phenolics processing method.
experiments by the method of solvent extraction, containing 2 - a company Naphthol class printing and dyeing wastewater processing. Specific processing method is: in a certain and temperature conditions, compared to the. cwl - M type centrifugal extraction machine zhongtong concentrate into the waste water and extraction agent, after mixing centrifugal separation by centrifugal extraction machine, load of organic phase and extraction residue respectively from different discharge hole; Then, with certain proportion, under a certain temperature, the centrifugal extraction machine zhongtong into reverse extraction agent and loaded organic phase, the final regeneration extractant and defection from different discharging hole, regenerative extraction solvent can be recycled back extraction system. 2 -
extraction processing Naphthol class printing and dyeing wastewater process is as follows:


in conclusion, using. cwl - Containing 2 - M type centrifugal extraction machine processing Phenolic printing and dyeing wastewater, high efficiency, convenient operation, and extractant can be repeatedly used, comply with the requirement of environmental protection and energy saving.






DE source extraction, recommend the use of. cwl - Containing 2 - M series centrifugal extraction machine processing Naphthol class help you understand the dyeing and printing wastewater 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.
