PROBLEM TO BE SOLVED: To provide a ballast water treatment apparatus capable of effectively removing air bubbles contained in discharged ballast water and dissolving various harmful influences caused by that the air bubbles are contained.SOLUTION: A ballast water treatment apparatus includes: an air bubble suction line L101 through which gas-liquid mixture W101 containing air bubbles caused to flow-in through an opening of one end part L101a near an upper closing part 13 on an inner part of a filter 520 of a ballast water filter device 20 circulates; a gas-liquid separator 100 which separates the gas-liquid mixture W101 supplied from the air bubble suction line L101 into gas W103 and liquid W102; a separation liquid line L102 through which the liquid W102 separated on the gas-liquid separator 100 is circulated toward a filter secondary side space 27; a separation gas line L103 through which the gas W103 separated on the gas-liquid separator 100 is circulated; and control means 9 which controls each part such that stored treatment water stored in a ballast tank 4 is filtered by the filter 520 and is irradiated with UV ray by a UV ray irradiation part 3.SELECTED DRAWING: Figure 2
【課題】排水されるバラスト水に含まれる気泡を効果的に除去し、気泡が含まれていることに起因する種々の弊害を解消することが可能なバラスト水処理装置を提供する。【解決手段】バラスト水濾過装置20のフィルタ520の内部の上閉止部13近傍の一端部L101aの開口から流入した気泡を含む気液混合体W101が流通する気泡吸引ラインL101と、気泡吸引ラインL101から供給された気液混合体W101を気体W103と液体W102とに分離させる気液分離器100と、気液分離器100で分離した液体W102がフィルタ二次側空間27に向けて流通する分離液体ラインL102と、気液分離器100で分離した気体W103が流通する分離気体ラインL103と、バラストタンク4に貯留される貯留処理水が、フィルタ520によって濾過され、紫外線照射部3により紫外線を照射されるように、各部を制御する制御手段9と、を備えるバラスト水処理装置。【選択図】図2
