摘　　要：根据MARPOL73/78公约,船舶舱底水必须经过油污水处理装置处理达标后方能排放。针对舱底水油水分离器工作负荷大、占地大、维护保养工作麻烦等诸多问题,提出了旋流分离、过滤分离、膜分离组合式三级舱底水处理工艺,并对该处理系统进行优化:采用预处理后选择性排放(通过油分浓度检测计取样)以减轻后继油水分离器的工作负荷;采用组合阀(浮球式自动排油阀/弹簧负荷式排水阀)以提高自动排油排水的稳定性;利用自动控制元件和PCL技术实现处理系统的自动控制以减轻船员的运行管理工作量。According to the International Convention MARPOL 73/78 for the prevention of pollution from ships,bilge water must be treated by oil sewage treatment devices to achieve standards before discharge. To resolve a number of problems of the oil-water separators used to treat ship bilge water, such as heavy workload, large footprint and difficult access to maintenance, this paper presents a three-stage treatment process formed by hydrocyclone and filtration and membrane separators. Then the system is optimized： adopting selective emission after pretreatment（monitored by oil concentration detector） to reduce the workload of subsequent oil-water sepa rators; using the combination valve（floating ball type automatic oil drain valve and spring load type drain valve）to improve the stability of automatic discharge of oil and water; and utilizing automatic control elements and PLC technology to realize system automatic control, so as to reduce the management workload of the crew.
