Abstract

To provide a process and an apparatus for treating surfactant-containing water by which foaming by blowing-in of ozone-containing gas is suppressed and stable treatment can be carried out. The surfactant-containing water is introduced into a flow passage 5 and is made to flow in a direction from an entrance 51 to an exit 52 and ozone is added thereto at two or more positions along a stream of the surfactant-containing water. Addition amount of ozone is largest at a last stage ozone reaction facility 20 arranged at a position nearest the exit 52. When ozone is added at two places, for example at a preceding side ozone reaction facility 10 and the last stage ozone reaction facility 20, about 5 to 40 vol.% of total ozone addition amount is added at the preceding side ozone reaction facility 10 and residual ozone is added at the last stage ozone reaction facility 20.
