Integrated treatment process for bilge water

存在许多用于处理舱底污水的解决方案。然而，几乎所有这些方法都使用某种形式的重力分离和正浮选来从水中去除油，这具有局限性，例如（i）20微米或更小的油颗粒不能被分离，以及（ii）舱底水中的各种含油废物会限制去除效率，特别是当存在非常稠密和高粘性的油（例如掩体油）时。泡沫浮选的电化学方法是有效的但昂贵的。含油水的生物修复在经济上是可行的，但由于需要长的保持时间，船上应用是不切实际的。目前研究工作的目标是：（i）对现有的所有舱底污水处理技术进行经济评价;（ii）开发一套实验室规模的舱底污水处理装置， 污染物，以及回收油。

There are many solutions exist for treating bilge water. However, almost all of them use some form of gravity separation and forth floatation for removal of oil from water, which have limitations such as (i) oil particles that are twenty micrometers or smaller cannot get separated and (ii) variety of oily wastes in bilge water can limit removal efficiency, especially when very dense and highly viscous oils such as bunker oil are present. Electrochemical methods for froth flotation are effective but expensive. Bioremediation of oily-water is economically viable, but an on-board application is impractical due to requirement of large holding time. The objectives of the current research work are: (i) economic evaluation of all the existing bilge water treatment technologies and (ii) develop a laboratory scale treatment train for treatment of bilge water for removal of the contaminants as well as recover the oil.
