<P>PROBLEM TO BE SOLVED: To provide a floating oil recovering method by which oil mixed in a water-soluble processing liquid that is used or has been used can be easily separated and recovered and to provide a floating oil recovering apparatus by which the floating oil recovering method can be actualized at a low cost. <P>SOLUTION: In the floating oil recovering method by which floating oil 7 that is mixed in the water-soluble processing liquid 2 stored in a liquid storage tank 1 and floats on a surface layer can be easily separated and recovered, the water-soluble processing liquid 2 is circulated inside the liquid storage tank 1 by sucking up the water-soluble processing liquid 2 from one end in the inside of the liquid storage tank 1 and returning it to the other end in the inside thereof. Further an oil isolation chamber 4 partitioned by a porous body through which the water-soluble processing liquid 2 and the floating oil 7 are made to pass is installed at a part where the water-soluble processing liquid 2 at the one end in the inside of the liquid storage tank 1 is sucked up and a gelling flocculant 11 which adsorbs the floating oil 7 to separate and recover it from the water-soluble processing liquid 2 is made to float in the oil isolation chamber 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
