摘要

(57) An object of the present invention Shi used as machinery and equipment of sewage treatment plant from wastewater runoff oil is mixed from water machine or the like, in the apparatus of the simple mechanism, surely the outflow oil was separated and collected, washed away oil to provide an apparatus for recovering outflow oil from sewage treatment plants in the machinery that is to be able to prevent the waste water mixed flows out as it is. Equipped with A drainage tank 4 is drainage from the machinery and equipment 1 of the sewage treatment plant is introduced, the waste water tank 4, hanging down from above, the partition plate 5 so as to form a flowing water space on the lower side, Located on the downstream side, as well partitioned by the weir 6 which is formed so as to be positioned above the lower end of the partition plate 5 to the upper end, wastewater inflow chamber 4 partitioned by a partition plate 5 1, a valve 7 for discharging the washout oil floating on the water surface to the drain tank 4 outside, is to be provided to car 8.
