PROBLEM TO BE SOLVED: To provide a liquid treatment apparatus capable of efficiently and exclusively recovering scum generated as a result of the flotation and separation of a removal target substance within a treatment target liquid.SOLUTION: This liquid treatment apparatus includes a flotation tank 11, a recovery tank 31, and a gas-liquid transfer pump 41. The flotation tank 11 induces the flotation and separation, to the liquid surface as scum Sc, of a removal target substance within a treatment target liquid A inside a flotation tank body 13 following the adhesion thereto of bubbles and then the discharge of the same to the outside via a scum retrieval port 22. The recovery tank 31 recovers, from the scum Sc and gas/liquid introduced into the interior thereof via the inlet 33 of a recovery tank body 32, the scum Sc via a filter 36 installed detachably within the interior of the recovery tank body 32. The gas-liquid transfer pump 41 not only suctions the scum Sc and gas/liquid from the scum retrieval port 22 of the flotation tank 11 through the recovery tank 31 interior but also suctions the gas/liquid D from the outlet 35 of the recovery tank 31 and then transfers the respective members to the downstream sides thereof. |
