摘　　要：在多层斜极分离设备的斜板下方安装一系列与料板垂直的翼板，构成了带翼斜板设备。把该设备用于石油污水的脱油处理，研究发现其具有较高的脱油效率和脱油深度。在进口含油浓度介于200～600mg／L之间，停留时间27.6min，平均脱油效率可达93．8％，出口平均含油浓度为1．8mg／L，粒径大于40μm的油滴基本均可脱除。文中还对进口含油浓度在300～400mg／L之间的出口含油浓度与表面负荷率的关系进行了论述。In this paper the finned slant plate separator is used to remove oil from the oily wastewater. The high effi cency and degree of oil removal were proved by experiments. In the range of oil concentration of 200-600 mg/L,for a retention time of 27. 6 min,average oil removal efficency is 93. 8 %,average outlet oil concentration can reach 21. 8 mg/L,oil particle diameter greater than 40μm can be removed mostly. The Correlation between the outlet oil concentration and the overflow rate is obtained in the range of inlet oil concentration of 300-400 mg/L.
