An aerated submerged fixed-film (ASFF) bioreactor was developed to treat an artificial wastewater based on crude oil. Bee-Cell 2000 was used as support media having porosity of 87% and a specific surface area of 650 m2 m(-3). The system was able to achieve 70.87-93.12% removal efficiencies of Chemical Oxygen Demand (COD) in the organic loading rate range of 1.310 to 15.797 g COD m(-2) day(-1). Data gained exhibited that the effluent COD concentration ranged between 68.68 and 292.60 mg L(-1) at organic loadings experienced. Therefore, an ASFF process showed that it was feasible to treat high oily wastewater in order to meet the discharge standards.
开发了一种曝气淹没式固定膜（ASFF）生物反应器，用于处理基于原油的人工废水。Bee-Cell 2000被用作支撑介质，其孔隙率为87%，比表面积为650 m2 m(-3)。该系统在1.310至15.797 g COD m(-2) 天(-1)的有机负荷率范围内，能够实现化学需氧量（COD）70.87 - 93.12%的去除效率。获得的数据表明，在所经历的有机负荷下，出水COD浓度在68.68至292.60 mg L(-1)之间。因此，ASFF工艺表明，处理高含油废水以达到排放标准是可行的。
