To enable wastewater to be efficiently treated in a wastewater treatment system which treats the wastewater generated in washing exhaust gas of a marine engine.SOLUTION: A wastewater treatment system comprises: a storage tank which stores wastewater generated by washing exhaust gas of a marine engine at a pressure higher than atmospheric pressure; a treatment tank which is disposed separately from the storage tank; and a flow passageway which has one end connected to the storage tank and the other end connected to the treatment tank and which causes the wastewater to flow therethrough from the storage tank to the treatment tank. The wastewater which passes through the flow passageway is made to be open to the atmosphere in the treatment tank and to thereby foam, to thereby cause an impurity in the wastewater to float to a surface for separation.SELECTED DRAWING: Figure 1

    【課題】船舶用エンジンの排気ガスの洗浄時に生じる廃水を処理する廃水処理システムにおいて、廃水を効率よく処理可能にする。【解決手段】廃水処理システムは、船舶用エンジンの排気ガスを洗浄して生じた廃水を、大気圧よりも高圧で貯留する貯留槽と、前記貯留槽とは個別に配置された処理槽と、一端が前記貯留槽に接続され、他端が前記処理槽に接続され、前記貯留槽から前記処理槽に向けて前記廃水を流通させる流通路と、を備える。前記流通路を通過した前記廃水を前記処理槽内で大気開放して発泡させることで、前記廃水中の不純物を浮上させて分離する。【選択図】図1
