TiO_2膜光催化法作为回用水处理工艺的试验研究

Experimental study on the photo-catalytic process for treatment of reuse water by TiO_2 fixed film

以印染废水为研究对象,探索了TiO2膜紫外光催化氧化法作为回用水处理工艺的可行性。实验证明,该技术具有使废水完全脱色、去除COD和BOD、杀菌消毒等综合性能,如果与除盐的工艺相结合,可以将废水处理成为工业冷却用水和生活杂用水。

The feasibility of photo-catalytic oxidation process for printing and dying wastewater renovation by TiO_2 fixed film is investigated. The results show that the process has several functions of completely removing color of the wastewater, reducing greatly COD and BOD, and disinfecting etc. If the process combines with salt eliminating process together, the wastewater can be treated to become cooling water or incidental water for living.
