Abstract

Drainage water containing an organofluorine compound is introduced into a raw tank () and then filtered through a filtration device (). Next, a microorganism, a micro-nanobubbling auxiliary agent and a nutrient are added thereto in a first transit tank () while micro-nanobubbles are generated thereinto by a micro-nanobubbling machine (), thereby giving treated water. This treated water is then fed into an active carbon column () and then the above-described organofluorine compound contained in the treated water is decomposed by the microorganism as described above.
