辽河油田曙光采油厂曙一联合站是一座稀油联合站,2010年将1000方斜板除油罐改造成悬浮污泥净化器,于2011年开展了悬浮污泥过滤工艺实验。悬浮污泥处理后出水含油量在0.4～1.2 mg/L悬浮物含量在2.2～8.4 mg/L范围内波动。通过现场验证,悬浮污泥过滤工艺优于气浮工艺,具有工艺流程短、处理效率高、改造投资少、运行费用低的优点,建议在稀油污水处理站上推广应用。
Shuguang Oil Production Plant Liaohe Shuguang United Station is a thin oil joint station in 2010 to 1000 sloping tank degreasing tank into a suspended sludge purifier in 2011 to carry out the suspension sludge filtration process experiments. Suspended sludge treatment effluent oil content of 0.4 ~ 1.2 mg / L suspended solids content fluctuations in the range of 2.2 ~ 8.4 mg / L. Through on-site verification, the suspended sludge filtration technology is superior to the air-float technology, with the advantages of short process flow, high treatment efficiency, less investment in transformation, and low operation cost. It is suggested to be popularized and applied in dilute-oil wastewater treatment stations.
