To provide a water treatment apparatus that allows selection of whether or not to discharge, to the outside of a ship, scrubber water to be discharged having been used for cleaning exhaust gas from a marine internal combustion engine.SOLUTION: A water treatment apparatus for treating scrubber water containing foreign matter removed by cleaning exhaust gas from a marine internal combustion engine, comprises: a foreign matter removal system for removing foreign matter from the scrubber water by separating the scrubber water into a residue containing the foreign matter and scrubber wastewater; a storage tank for storing the residue and the scrubber wastewater; a scrubber drain pipe, a first drain pipe and a second drain pipe for discharging the scrubber wastewater; and a drain path branching valve for branching the scrubber drain pipe into the first drain pipe and the second drain pipe. When the marine internal combustion engine operates on alternative fuels, the drain path branching valve connects the scrubber drain pipe to the first drain pipe leading to the outside of a ship, and when the marine internal combustion engine operates on fossil fuels, the drain path branching valve connects the scrubber drain pipe to the second drain pipe leading to the storage tank.SELECTED DRAWING: Figure 1

    【課題】舶用内燃機関からの排ガスの洗浄に用いられた排水対象のスクラバ水について、船外へ排水するか否かを選択可能な水処理装置を提供すること。【解決手段】本発明の一態様である水処理装置は、舶用内燃機関からの排ガスを洗浄して除去した異物を含むスクラバ水を処理する装置であって、スクラバ水を異物含有の残渣とスクラバ排水とに分離してスクラバ水から異物を除去する異物除去系統と、残渣およびスクラバ排水を貯蔵する貯蔵タンクと、スクラバ排水を排出するためのスクラバ排水管、第1排水管および第2排水管と、スクラバ排水管を第1排水管と第2排水管とに分岐させる排水路分岐弁と、を備える。舶用内燃機関が代替燃料運転する場合、排水路分岐弁はスクラバ排水管と船外に通じる第1排水管とを連通させ、舶用内燃機関が化石燃料運転する場合、排水路分岐弁はスクラバ排水管と貯蔵タンクに通じる第2排水管とを連通させる。【選択図】図1
