The invention discloses a
phenol-containing
wastewater treatment method and a device thereof, and the method comprises the following steps: separating
phenol-containing
wastewater into a high-concentration mother solution and a low-concentration washing solution, respectively treating the mother solution and the washing solution, extracting the washing solution by adopting an extraction agent, carrying out heavy component removal treatment on the mother solution, and then extracting the mother solution by adopting the extraction agent; performing heavy component removal treatment on the
mother liquor through a dehydrating
tower, extracting the light components at the top of the dehydrating
tower by adopting an extracting agent, and arranging an
evaporator at the bottom of the dehydrating
tower and used for evaporating materials at the bottom of the dehydrating tower; combining light components at the top of the dehydrating tower with the washing liquor, and extracting by adopting an extracting agent; wherein the
evaporator is a scraper type
evaporator. The device comprises a dehydrating tower, an extracting tower, a stripping tower, a separating tower, a product tower and a regenerating tower. According to the method, the
raw material sodium chloride does not need to be purchased additionally,
phenol sodium salt is not generated additionally, the sales way of the phenol
sodium salt does not need to be considered, and waste residues are directly incinerated; and the
recovery purity of phenol products is high.
