Based on the practical experience in design and operation of three full-scale membrane bioreactors (MBR) for municipal wastewater treatment that were commissioned since 1999, an overview on the different design concepts that were applied to the three MBR plants is given. The investment costs and the energy consumption of the MBRs and conventional activated sludge (CAS) plants (with and without tertiary treatment) in the Erft river region are compared. It is found that the specific investment costs of the MBR plants are lower than those of comparable CAS with tertiary treatment. A comparison of the specific energy demand of MBRs and conventional WWTPs is given. The structure of the MBRs actual operational costs is analysed. It can be seen that energy consumption is only responsible for one quarter to one third of all operational expenses. Based on a rough design and empirical cost data, a cost comparison of a full-scale MBR and a CAS is carried out. In this example the CAS employs a sand filtration and a disinfection in order to achieve comparable effluent quality. The influence of membrane lifetime on life cycle cost is assessed.
基于自 1999 年以来投入运行的三个全规模城市污水处理膜生物反应器（MBR）的设计和运行的实际经验，概述了应用于这三个 MBR 工厂的不同设计理念。比较了埃尔夫特河流域 MBR 和传统活性污泥（CAS）工厂（带或不带三级处理）的投资成本和能源消耗。发现 MBR 工厂的特定投资成本低于具有三级处理的可比 CAS。给出了 MBR 和传统 WWTP 的特定能源需求的比较。分析了 MBR 实际运营成本的结构。可以看出，能源消耗仅占所有运营费用的四分之一到三分之一。基于粗略的设计和经验成本数据，对全规模 MBR 和 CAS 进行了成本比较。在这个例子中，CAS 采用砂滤和消毒以达到可比的出水质量。评估了膜寿命对生命周期成本的影响。
