摘要
对九江炼油厂污水处理现有的运行模式进行了综合评价。该装置采取两级生化法和生物膜法相结合的方法处理炼油废水。两级生化法ＣＯＤ负荷率在０．２０～０．５２ｋｇ／（ｋｇ．ｄ），ＣＯＤ去除率在６０％以上，酚负荷率≤０．０８ｋｇ／（ｋｇ．ｄ），酚去除率在９９％以上。生物膜法ＣＯＤ、ＮＨ３－Ｎ去除率均在６０％以下。评价的目的在于提高ＣＯＤ、ＮＨ３－Ｎ去除的稳定性。
The Article comprehensively evaluated the rount model of Jiujiang refinery wastewater treatment unit. The unit adopts twograde biochemistry and onegrade biomembrane process. Twograde bichemistry process: the loading of COD is 20052kg/(kg.d), the removal rate of COD is more than 60%, the loading of phenol is008kg/(kg.d), the removal rate of phenol is more than 99%. biomembrane process: the removal rate of COD and NH3-N are less than 60%. The purpose of its evaluation is to enhance the removal rate of COD and NH3-N, and brings forward progress of route model.
