The invention relates to a
phenol-containing
wastewater treatment method, which adopts liquid membrane extraction to treat
phenol-containing
wastewater, and comprises the following steps: 1, measuring the
phenol content in the phenol-containing
wastewater, adding a liquid membrane extract according to the measured phenol content, and fully mixing the liquid membrane extract and the phenol-containing wastewater at a stirring speed of 60r / min, reacting phenol in the phenol-containing wastewater with
sodium hydroxide in the liquid membrane extraction liquid for 10 min; 2, performing standing for 10 min after the reaction is completed, layering a water phase and an
emulsion phase, and separating the water phase from the
emulsion phase to obtain an
emulsion containing
sodium phenate; and 3, stirring the emulsion containing
sodium phenate obtained in the step 2 at a stirring speed of 1500r / min for 3-10min for demulsification, performing standing for 20min after demulsification is completed, layering a water phase and an
oil phase, separating the
oil phase from the phase, and continuing to use the
oil phase as a preparation
raw material of the liquid membrane extraction liquid. According to the method, phenolic compounds in the wastewater can be effectively enriched into the emulsion, the extraction liquid can be repeatedly used, the extraction efficiency is high, the
energy consumption is low, and resources can be effectively saved while wastewater treatment reaches the standard.
