Rotating biological contactor system (lab unit)
The RBC was fed with the primary treated wastewater at an organic loading rate of 0.03 kg COD/m3 /day.The results of the analysis of the treated effluents are pre-
sented in (Table 1 & Fig.9).COD and BOD residual values ranged from 80 to 303 mgO2 /l and from 30 to 146 mgO2 /l with an average of 144 and 73 mgO2 /l,respectively.Oil and grease varied from 5 to 66 mg/l with an average of 20.9 mg/l.The average of total suspended solids was 23.6 mg/l.From the available data,it can be concluded that the treated wastewater is in compliance with the standards given by the Egyptian law,which regulates the discharge of industrial wastewater into the sewerage system.
Anaerobic treatment system
The UASB reactor was fed during the investigation period with the pretreated wastewater.Two organic loading rate were investigated namely 6.8 and 9 kg
COD/m3 .d,at hydraulic retention time of 8 and 6 hours respectively.
The results obtained during these chores are illustrated graphically in Fig.10.Available data showed that increasing the applied organic loading rate from
6.8 to 9 kg COD/m3 .d did not affect the COD removal rate.During the two loads the average COD removal ranged between 60% and 61%.The corresponding val-
ues were 1045 and 1038 mgO2 /l (Table 1).Also,the BOD removal was not affected with changing the organic loading rates.The BOD average removal values
were 71% and 73%.The residual values of the total suspended solids were 43 and 57 mg SS/l.From the previous results,the 6 hours detention time was the recommended duration for the anaerobic treatment.These values are in agreement with the standards set by the Egyptian law for discharging treated wastewater into
the sewerage system.

生物转盘小试试验系统
生物转盘系统以经预处理的污水为研究对象,有机负荷为0.03 kg COD/m3 /day.污水分析结果如表1和图9所示.出水COD浓度范围为80~303mg/L,平均值为144mg/L,BOD出水浓度范围为30~146mg/L,平均值为73mg/L.油脂类出水浓度范围为5~66mg/L,平均值为20.9mg/L.平均总悬浮物浓度为23.6mg/L.根据已有数据可知,经处理的污水可以达到埃及法律规定的标准,该标准规定了排入污水处理厂的工业污水的流量.
厌氧处理系统
试验期间,UASB反应器以经预处理的污水为研究对象,试验控制两个有机负荷,分别为6.8 kgCOD/m3 .d和9 kgCOD/m3 .d.水力停留时间分别控制在8h和6h,实验结果如图10所示.由数据可知,将有机负荷从6.8提高到9 kgCOD/m3 .d不会对系统COD去除效果产生影响,两有机负荷条件下的COD平均去除率分别为60%和61%.相应的进水COD分别为1045和1038 mgO2 /l（如表1所示）.负荷变化也没有对BOD去除效果产生影响,BOD平均去除率分别为71%和73%.剩余悬浮固体分别为43和57 mg SS/l,根据已有结果,建议厌氧处理的水力停留时间为6小时,该值符合埃及法律规定的排入污水处理厂的工业废水的规定标准.
