PROBLEM TO BE SOLVED: To provide a ballast water treatment apparatus and a filter cleaning method of the ballast water treatment apparatus which shorten a cleaning time from stoppage of water treatment operation until restart of the water treatment operation after cleaning a filter when a clogged filter is cleaned during the water treatment operation.SOLUTION: A ballast water treatment line 1 is provided with a filter device 3 having a filter 10 arranged in a casing 9 and a cleaning mechanism 11 for cleaning the filter 10, and an ultraviolet irradiation device 4 arranged on a downstream side of the filter device 3. A cooling water passage line 17 for passing cooling water through the ultraviolet irradiation device 4 is arranged side by side with the ballast water treatment line. Operation control means 25 has a control function of maintaining a lighting state of the ultraviolet irradiation device 4 while stopping water treatment operation when the filter 10 is clogged, passing the cooling water from the cooling water passage line 17 to the ultraviolet irradiation device 4, and restarting the water treatment operation after cleaning the filter device 3, and stopping passage of the cooling water to the ultraviolet irradiation device 4.SELECTED DRAWING: Figure 1

    【課題】 水処理運転中に、目詰まりしたフィルタを洗浄する場合の、水処理運転の停止からフィルタの洗浄後の水処理運転の再開までの洗浄時間の短縮化を図るバラスト水処理装置およびバラスト水処理装置におけるフィルタ洗浄方法を得る。【解決手段】 ケーシング9内にフィルタ10を設けるとともに、フィルタ10を洗浄する洗浄機構11を設けた濾過装置3と、濾過装置3の下流側に紫外線照射装置4を備えたバラスト水処理ライン1に、紫外線照射装置4に冷却水を通水する冷却水通水ライン17を併設し、フィルタ10の目詰まり時に、水処理運転を停止させるも紫外線照射装置4の点灯状態を維持させるとともに、冷却水通水ライン17から紫外線照射装置4に冷却水を通水させ、濾過装置3の洗浄後に水処理運転を再開するとともに、紫外線照射装置4への冷却水の通水を停止させる制御機能を有する運転制御手段25を備えた。【選択図】 図1
