Abstract

Abstract:

Six strainsof yeastsscreened from soil of oil plant have been utilized in activated-sludge process to treat the highly concentrated oil-bearing wastewater directly and continuously.The removal rate of COD_Cr and oil reaches87.1%～97.3% and92.9%~99.8% respectively when the influent wastewater contains12000mg/L COD Cr and3500mg/L oil and the BOD 5-yeast load isbetween1.0～2.5kg/(kg·d).The resultsindicate the optimum BOD5-yeast load(a unit yeast)is 1.0～ 1.5kg/(kg·d)from the angle of sedimentation.

Key words: yeast, highly concentrated oil-bearing wastewater, BOD 5-yeast load

摘要：

利用现场筛选到的6株酵母菌，采用活性污泥法工艺对高浓度含油废水进行了连续处理研究。在进水COD_Cr约12000mg/L，油约3500mg/L，BOD5鄄yeast负荷1.0～2.5kg/(kg·d)情况下，COD_Cr、油去除率分别达到87.1%～97.3%和92.9～99.8%;并从沉降性角度得出混合酵母菌处理该废水的理想负荷(以单位酵母菌计)为1.0～1.5kg/(kg·d)。
