| 摘 要： | 探讨了固定在颗粒活性炭上的二氧化钛光催化剂(TiO2/GAC)降低中水BOD5的效果及影响因素,实验表明仅光照不投加TiO2/GAC,BOD5的去除率为8.1%;仅投加TiO2/GAC无光照,BOD5的去除率为9.8%;而投加TiO2/GAC并光照,BOD5的去除率为54.7%.TiO2/GAC对BOD5的去除率随光照时间和光照强度的增加而增加.

| Abstract: | The effects and factors of TiO2/GAC photocatalyst immobilized on the active carbon on reducing reclaimed water BOD5 were studied.The results showed that the reduction of BOD5 was 8.1% by illumination without TiO2/GAC photocatalyst,9.8% with TiO2/GAC photocatalyst without illumination,and 54.7% with both TiO2/GAC photocatalyst and illumination,respectively.The reduction of BOD5 improved with the increase of illumination time and intensity. |
