<P>PROBLEM TO BE SOLVED: To provide a pressure flotation separator in which oil-water separation can be carried out with a simple structure using a non-explosive gas, operation control is easy, and an application range can be widened. <P>SOLUTION: A floating tank 2 is provided with a pressure pump 3 for sending waste water WO containing oil. A non-explosive gas G is supplied, and a flocculant T is added to the pressure pump 3. Water-oil separation is carried out in the floating tank 2 using the pressure flotation separator 1 which is configured so that the non-explosive gas G, the flocculant T and the waste water WO containing oil are mixed together in the pressure pump 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
