| Abstract: | Terephthalic acid wastewater was treated by membrane technology combined with traditional bio-treatment technology. The running of membrane system and the quality of permeation was stable and credible, under the conditions of ultra filtration（UF） using dead filtration. UF flux was about 40 - 60 L·m^-2·h^-1, and reverse osmosis （RO） using low fouling element filtrate flux was 15 - 20 L·m^-2·h^-1. The reuse rate of this system was 70% and the process was stable operated with purified water meeting the requirements for water reuse. |
