Rotating biological contactor treatment system in the factory
The RBC was selected and installed by the factory as it has the advantage of low operating and maintenance costs.The RBC was fed continuously with the effluent
from the pretreatment unit.It consists of a four stages RBC.Each stage was filled with plastic packed materials in the form of rings which provide a total surface
area of 4000 m2 (Fig.11).The discs were rotated at 3-5 rpm with approximately 45% of the surface area submerged in the wastewater.The total vilumn of the system was 6 m3 .The hydraulic load applied to the RBC was 0.02 m3 /m2 .d.The water is dosed to the RBC by rotating cups mounted on a large disc attached to the
main shaft.The factory RBC performance was monitored.Table 2 shows the characteristics of the treated effluent.Residual values of COD and BOD ranged
from 127 to 543 and 25 to 385 mgO2/l with average values of 362 and 139 mgO2/l,respectively.Corresponding average removal values were 86% and 88%.
The average percentage removal of total suspended solids was 73%.The corresponding residual concentration was 95 mg/l.The average residual value of oil
and grease was 27 mg/l with 77% corresponding removal value.The characteristics of the treated effluent are comparable with the results obtained by using the
lab unit RBC.
Conclusion
The obtained results using the activated sludge,rotating biological contactor and UASB technology proved to be efficient for the treatment of wastewater dis-
charged from a flavor production factory.The wastewater characteristics of each treatment process are in compliance with the Egyptian law which regulates the
discharge of industrial wastewater to the sewerage system.The factory installed RBC proved to be efficient and reliable on account of the characteristics of the
treated effluent as compared to the results obtained from the lab unit.

厂内旋转生物接触器(又称“生物转盘”)处理系统
该厂选择装设旋转生物接触器(以下简称“接触器”),是因为这种设备的运作成本和维修成本都较低.从预处理设备输出的流出物会被不断输送至接触器.接触器有四个阶段,每个阶段都装设了由塑料包装成环状的物料,合共提供达4,000平方米的总表面面积(见图11).这些转盘以每分钟3-5转的速度旋转,并保持约有45%的表面面积浸於废水中.整个系统的总体积为6立方米.接触器所承受的液压负荷为每日每平方米0.02立方米.废水是经由装设於主轴的大盘上的转杯输送至接触器.整个接触器的处理效果都受到监察.表2展示了经处理后的流出物特点.剩余化学需氧量和剩余生物需氧量分别介乎每公升127至543毫克氧和25至385毫克氧之间,而平均值则分别为每公升362和139毫克氧.相应的平均清除率分别达86%和88%.总悬浮固体的平均清除率为73%.相应的残余浓度为每公升95毫克.平均残余油脂为每公升27毫克,其相应清除率达77%.这些处理后流出物的特点与实验室接触器所取得的结果相若.
结论
根据活化淤泥、旋转生物接触器和升流式厌氧污泥床等技术所取得的结果证明,这些技术都适用於处理从调味料制造厂排出的废水.每种处理过程所输出的废水,都符合埃及法律对工业废水排入公共污水收集系统的相关规定.此外,经接触器处理后的流出物特点,与实验室中接触器所取得的结果相若,因此证实,该厂所装设的旋转生物接触器属有效和可靠.
