- 摘要：实验室规模间歇排放延时曝气(IDEA)生物反应器及TiO2光催化反应器组成的生物 光催化反应器系统,处理由3种不同工业染料合成的人工配制印染废水。结果表明,此系统能够有效去除印染废水中的生物可降解及不可生物降解的COD, 且能够将废水完全脱色。该系统有很高的抗冲击负荷及处理高浓度印染废水的能力。
- Abstract：Synthetic dyeing wastewater consisting of the three types of commercial dyes with different CODs(around 900 and 300mg/L respectively) were preliminarily treated by an Intermittently Decanted Extended Aeration reactor(IDEA) for BOD removal, and then treated by a TiO2 sensitized photoreactor for a further COD removal and decolourization. A bio photoreactor system was designed to combine this photocatalytic reactor with the IDEA reactor for the treatment of the dyeing wastewater. The performances of this combined bio photoreactor system with and without recycle water were investigated and compared. The efficiency for decolurization and COD removal of the system with recycle water was similar to that without recycle water, but with a high capacity of eliminating the effects caused by a shock loading. The system can treat dyeing wastewater with a higher organic concentration.
