The waste water treatment process includes the biological treatment of the waste water under pressure and the pressure drop, and substantially removes the solid gas flotation fluid under reduced pressure. There is a device for waste water treatment, which includes a pressurized biological treatment plant (18) with reduced pressure. The pressurized biological process includes three biological reactors (12, 14, 16), while the reactor (12) is deoxide n, the reactor (14) is denitrifying to the reactor (16) is nitrification n. \ T |
