The invention relates to the technical field of ship sewage treatment, and provides a ship cargo hold sewage treatment system. According to the system, a first sewage cabin and a second sewage cabin with inclined cabin bottoms are communicated through a connecting pipeline; after the sewage is deposited in the first sewage cabin by gravity, clean water in the first sewage tank flows into the second sewage tank for cleaning through the first suction port with the higher level, an extra marine power source is not needed, and the water consumption for cleaning is reduced; and after total deposition, the cabin bottom in an inclined state is easier to discharge the deposits out of the outboard through the first stop valve and the second stop valve, the inner wall of the cabin is easier to clean, and the cleaning requirement is met. The invention further discloses a control method, by controlling opening and closing of the second stop valve, the third stop valve and the fourth stop valve, the inner wall of the cabin can be better cleaned, use of power energy is reduced, and the cleaning effect of the ship cabin is easier to achieve.
本发明涉及船舶污水处理技术领域,提供一种船舶货舱污水处理系统,该系统通过将舱底均呈倾斜状态的第一污水舱和第二污水舱通过连接管道连通,当污水在第一污水舱采用重力沉积后,再通过水平更高所述第一吸口将第一污水舱内的较为干净的水流入所述第二污水舱进行清洗,不需要额外的船用动力源且减少清洗的用水量;再通过总的沉积后,呈倾斜状态舱底更易于将沉积物通过第一截止止回阀、第二截止止回阀排出至舷外,更易于对舱室内壁进行清洁,达到清洁要求。本发明还公开了控制方法,通过控制第二截止阀、第三截止阀、第四截止阀开闭,能够更好地对舱室内壁进行清洁,减少动力能源的使用,且更易于实现船舶舱室的清洁效果。
