為符合MARPOL國際公約對船舶排放污水含油量之規定，本研究針對動態旋流油水分離器進行研究。所設計之基本構造包括變速馬達、轉盤、入口段、旋流管、與尾端出口段。污油廢水由入口段進入，轉盤葉片帶動進行旋流，進入旋流管時旋流程度增大。
污油廢水由出口段軸心處排出再次循環進行分離，經處理排水由出口內壁開口排出。四種試驗油之實驗結果得知馬達轉速越高時分離效果越佳。初級處理可得到98%之分離效果但排水含油量依然太高。二級處理時潤滑油可達到低於15ppm之排放標準，但漁船用油仍然高於排標準。本研究之設計尚有缺點，預期可改良設計得到更佳之分離效果。

To comply with the 15ppm oil concentration of oily wastewater discharge regulated by MARPOL. This study practically designed a set of dynamic hydrocyclone oily water separator. Basically it consists of a variable-speed motor, a rotor, an inlet section, a cyclone section, and a tail outlet section. The oily waste water enters form inlet section. The rotating motion of rotor vanes forces the waste water to undergo swirling motion. The swirling is enhanced when the waste water moves into cyclone section. Oily water is discharged from center of outlet section, and recycled for further separation, The processed water discharges from the circumference of outlet section. The experimental results of four test oils show that better separation results are obtained at higher rotor speeds. A result of 98% oil separation is obtained in primary processing. Yet the oil content of water discharge is still too high, The 15ppm regulation is fulfilled in secondary processing of using a lubricant oil. However, not-so-good results are obtained in secondary of using fishing fuels.
The design in this study still has come deficiencies. It is anticipated that better separation results may be obtained with an improved design.
