[0002] Gray water generated on ships is relative to black water. The black water we usually refer to is mainly water from toilets, urinals or wards, while gray water is water from washbasins and floor drains, such as kitchen waste water, bathing water, etc. At present, the gray water generated by domestic ships in my country is not only large in volume, but also basically no ship gray water collection or treatment equipment is installed on the ship. All domestic sewage from ships is directly discharged into the navigation waters. Therefore, when ships enter the Three Gorges Reservoir area, they cannot meet the current zero-emission requirements of my country for the Yangtze River waters, especially the Three Gorges Reservoir area.
