The invention provides a treatment method for discharged water containing surfactant. When carrying out film separating treatment to discharged water containing surfactant, it can prevent the film's flux reducing and keep continuous and steady treatment for a long term; before film separating treatment, oxidize ozone under alkali conditions, oxidize and decompose the surfactant in discharged water, carry out film separating treatment to the alkali oxidization treatment water. Because supplying the alkali water directly to film separating device without neutralizing it, it can restrain contamination caused by microorganism in the film separating device and prevent the flux reducing for a long time; because oxidizing ozone under alkali conditions before film separating, the surfactant in discharged water can be decomposed and eliminated, it can prevent film's flux from reducing caused by surfactant and keep continuous and steady treatment for a long term. |
