酵母菌处理高浓度含油废水的研究
Study on the treatment of highly concentrated oil-bearing by yeasts
【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CODCr约12000mg/L,油约3500mg/L,BOD5鄄yeast负荷1.0～2.5kg/(kg·d)情况下,CODCr、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)。
【Abstract】 Six strainsof yeastsscreened from soil of oil plant have been utilized in activated - sludge processto 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 op - timum BOD 5 - yeast load ( a unit yeast ) is1.0 ～ 1.5kg /( kg · d ) from the angle of sedimentation.
