Abstract: Provided is a liquid processing apparatus and a liquid processing method for reducing a waste amount of a high specific gravity liquid. The liquid processing apparatus includes: a supply pump; a bubble tank including an inflow port, an overflow port, and a return port; a microbubble generator disposed outside the bubble tank; a recovery tank having a recovery port to recover the processing liquid overflown from a first liquid level to the tank; a separation tank including a settling tank connected to the overflow port, and a floating tank connected to the settling tank at a lower portion, and an ejector having a inlet port connected to the supply pump, a suction port connected the suction body, and a discharge port connected to the return port.

Abstract: Provided are a liquid treatment apparatus and a liquid treatment method for reducing a waste amount of a high specific gravity liquid. The liquid treatment apparatus includes: a liquid supply pump to supply a treatment liquid stored in a tank; a bubble tank into which the treatment liquid flows, and including a floating matter discharge port arranged near a liquid surface of the treatment liquid, and to discharge a floating matter floated on the treatment liquid; a microbubble generator arranged outside the bubble tank, and to generate microbubbles by mixing air into the treatment liquid supplied from the liquid supply pump; a separation tank connected the bubble tank at a lower portion of the bubble tank; and a circulation pipe configured to return the treatment liquid overflown from the liquid surface in the separation tank to the tank.
