Abstract: In order to avoid the pollution of the water environment by the floating dock and the liquid pollutants produced in its operation, this paper takes the 48 000 t lifting floating dock as an example, and on the basis of meeting the latest environmental protection laws and regulations, as well as in combination with the existing environmental protection technology, puts forward a technical scheme for the physical pollution prevention of various liquid pollutants. By adopting the anti-pollution structure of floating dock and the discharge control of floating dock etc, it can effectively prevent the pollution of liquid pollutants to water environment. This study can be used for reference to the anti-pollution design technology of floating dock and provide reference for the relevant anti-pollution design and construction standards of floating dock.

1" " "引言
隨著經濟的發展和海洋資源的不斷開發利用,人們及相關政府主管機關越來越重視環保問題,尤其是船舶修造方面,地方政府相繼出臺政策推動船舶修造企業改造升級,以期減少對廠區周圍水域的污染。浮船塢,簡稱浮塢,是一種用于修、造船的工程船舶,它不僅可用于修、造船舶,還可以用于打撈沉船、運送深水船舶通過淺水的航道等[1]。然而,關于有效阻止浮船塢液態污染物污染的相關技術較少見諸于報刊雜志,可供參考的資料和研究較為缺乏。近年來,雖然海事主管機關推進遠程視頻監督等創新監管方法,浮船塢內修造船作業導致的污染事故有所下降,但由于缺少技術層面的解決方案,仍然無法從根本上降低浮船塢作業水域污染事故的隨機性和危害性。
浮船塢由底部浮箱與兩舷塢墻組成,連續不可分開[2]。本文以48 000 t舉力浮船塢為例進行研究分析,該浮船塢由華潤大東造船廠建造,建造完成后用于泰國曼谷灣Leam chabang 港的Unithai shipyard amp;engineer Ltd的水域[3]。……
