| titleOfInvention | Treatment method of T acid industrial wastewater |
| abstract | The invention provides a treatment method of T acid industrial wastewater, which comprises the following steps: (1) adding an extracting agent consisting of a diluent and a complexing agent 2, 6-diethylanilino-N-ethyl propyl ether into the T acid industrial wastewater for extraction, and performing oil-water separation; (2) adding a stripping agent inorganic alkali solution into the organic phase extracted in the step (1), so that the T acid in the organic phase is transferred into a stripping solution in an ion form, and simultaneously regenerating the extracting agent; (3) adding an inorganic acid solution into the back extraction water phase in the step (2) for acidification treatment to separate out T acid; (4) and filtering the precipitated solid to obtain the T acid product. Compared with the prior art, the extracting agent used in the invention has high efficiency and high selectivity, and can be recycled after back extraction treatment; the method for treating the T acid industrial wastewater has the advantages that the COD removal rate is up to more than 98 percent, and the T acid product recovery rate is higher than 85 percent. |
