Abstract

The study was based on an external pilot-scale membrane bioreactor (MBR) with a ceramic membrane compared to a conventional activated sludge process (ASP) plant. Both systems received their influent from domestic wastewater. The MBR produced an effluent of much better quality than the ASP in terms of total suspended solids (TSS), 5-day biological oxygen demand (BOD) and chemical oxygen demand (COD), total phosphorus (TP) and total nitrogen (TN). Other effluent quality parameters also indicated substantial differences between the ASP and the MBR. This study leads to the conclusion that in the case of domestic wastewater, MBR treatment leads to excellent effluent quality. Hence, the replacement of ASP by MBR may be justified on the basis of the improved removal of solids, nutrients, and micropollutants. Furthermore, in terms of reuse the high quality of the treated water allows it to be reused for irrigation.

摘要

该研究基于一个外部中试规模的膜生物反应器（MBR），其采用陶瓷膜，与传统活性污泥法（ASP）处理厂进行对比。两个系统的进水均来自生活污水。就总悬浮固体（TSS）、五日生化需氧量（BOD）、化学需氧量（COD）、总磷（TP）和总氮（TN）而言，MBR产生的出水水质比ASP好得多。其他出水水质参数也表明ASP和MBR之间存在显著差异。本研究得出的结论是，对于生活污水，MBR处理可产生优质的出水。因此，基于对固体、营养物和微污染物去除效果的改善，用MBR替代ASP可能是合理的。此外，就水的回用而言，经处理后高质量的水可用于灌溉。
