| 水面浮油回收船 |
oil recovery vessel (Boats used for recovering oil spilled at sea from oil tankers. The recommended procedure is to contain and physically recover the spill with or without the use of adsorbents. This approach entails three processes: 1. confinement of the spill by spill booms; 2. recovery of the spill by sorbing agents; 3. physical removal of the contained oil by oil pick-up devices) |

water hyacinth (Floating aquatic plant, Eichornia crassipes of tropical America, having showy bluish-purple flowers and swollen leafstalks: family Pontederiaceae.
