【 摘 要 】

A pilot plant was studied to investigate a new method for reclaiming wastewater from the industrial area of Jurong, producing high quality water from it for industrial reuse. The new process used an up-flow anaerobic sludge blanket (UASB) and a membrane bioreactor (MBR) with a submerged ceramic flat sheet membrane. The feedwater from the chamber with the industrial wastewater was high in chemical oxygen demand (COD), which varied between 644 and 2,380 mg L–1 and had a pH range of 6.7–7.1. The MBR process was operated in series at a flux of 18–25 Lm–2 h–1 for 100 days. The average COD and the biological oxygen demand of products of the above system were 155 and 9 mg L–1, respectively. The results of this study indicated that a UASB-ceramic MBR process was capable of stably producing high quality water for industrial reuse from industrial wastewater.
