Naphthalene sulfonic acid kind of organic wastewater, most of the high concentration, big toxicity, colour and lustre is deep and complicated composition, the harm of human body and environment are more serious. Because the stable structure, organic matter in waste water using general oxidation method and biochemical method is difficult to remove the impurity in the water, while using centrifugal extraction method can achieve good treatment effect.
the experiment selects the amine system composed of extractant and kerosene as the complexation extraction agent, in a chemical plant of naphthalene sulfonic acid type organic wastewater as treatment object,. 。 。

naphthalene sulfonic acid kind of organic wastewater, most of the high concentration, big toxicity, colour and lustre is deep and complicated composition, the harm of human body and environment are more serious. Because the stable structure, organic matter in waste water using general oxidation method and biochemical method is difficult to remove the impurity in the water, while using centrifugal extraction method can achieve good treatment effect.
the experiment selects the amine system composed of extractant and kerosene as the complexation extraction agent, in a chemical plant of naphthalene sulfonic acid type organic wastewater as treatment object, under certain experimental conditions, the use of CWL50 - M type centrifugal extraction machine was carried out on the material liquid centrifugal extraction. According to the results in the wastewater COD removal rate as high as 96%; Then, with a 20% alkali solution as extraction agent to reverse extraction of loaded organic phase, found that after the extraction of regenerative extraction agent can be repeatedly used to many times and will not affect the extraction effect.
the centrifugal extraction method of naphthalene sulfonic acid type of organic wastewater treatment process is as follows:


in conclusion is: use. cwl - M series centrifugal extraction machine naphthalene sulfonic acid type of organic wastewater treatment, high efficiency, simple operation and treatment effect is better than that of general oxidation method and biochemical method.






DE source extraction, recommend the use of. cwl - M type centrifugal extraction machine containing naphthalene sulfonic acid type printing and dyeing wastewater treatment 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.
