PURPOSE: To provide a cleansing wastewater treatment apparatus for a marine exhaust gas capable of purifying scrubber contaminated water and lowering SS concentration and oil concentration to such a level as to be disposed into the ocean.CONSTITUTION: A cleansing wastewater treatment apparatus includes an exhaust gas re-circulation unit 1 and a buffer tank 5 configured to store scrubber waste water. The apparatus further includes: a scrubber circulatory system for scrubber water and scrubber waste water circulating at a pressure higher than atmospheric pressure via a circulation pump 3 formed between the buffer tank 5 and the exhaust gas re-circulation unit 1; and a solid-liquid separation machine configured to introduce the scrubber waste water inside the buffer tank 5 to separate into separated liquid and a solid content. A solid-liquid separation circulatory system is formed by a waste water feeder pipe 14 and a return pipe 16. The buffer tank 5 includes a scrubber circulatory system and the solid-liquid separation circulatory system formed independently. Scrubber water to be supplied to the exhaust gas re-circulation unit 1 from the buffer tank 5 in the scrubber circulatory system contains scrubber water purified at the solid-liquid separation circulatory system.SELECTED DRAWING: Figure 1

    【目的】スクラバ汚染水を浄化して海洋投棄できる程度までSS濃度及び油分濃度を低下できる船舶排ガスの洗浄排水処理装置の提供。【構成】排ガス再循環ユニット1と、スクラバ排水を貯留するバッファタンク5とを備え、バッファタンク5と排ガス再循環ユニット1との間に、循環ポンプ3を介して大気圧より高圧で循環するスクラバ排水とスクラバ水とのスクラバ循環系が形成されており、バッファタンク5内のスクラバ排水を導入して分離液と固形分に分離する固液分離機を備え、排水供給配管14と返送配管16とにより固液分離循環系が形成されており、バッファタンク5には、スクラバ循環系と固液分離循環系が各々独立して形成されており、スクラバ循環系におけるバッファタンク5から排ガス再循環ユニット1に供給するスクラバ水は、固液分離循環系で浄化されたスクラバ水を含む。【選択図】図1
