| 摘 要： | 以光化学氧化法处理垃圾渗滤液为研究对象，对不同光反应器、H2O2的投加方式、渗滤液曝气、不同光源以及原水初始COD浓度等影响因素进行了探讨，实验结果表明：旋转式反应器对COD去除效果最高，降膜反应器虽效率略差，但结构简单，光源无污染，易于在工程中使用；H2O2一次性投加更有利于COD的去除；在合适时间段采取曝气方式可提高紫外光氧化反应速度；紫外灯光对COD去除较好，而太阳光对COD去除稍差，可能耗低、成本低，在污染物治理时有广阔的应用前景；COD去除效率随原水初始COD浓度的增加而增加。

| Abstract: | Landfill leachate treatment by photochemical oxidization was selected to investigate influencing factors about its removal efficiency.In this study,influencing factors include three different photo reactors,H2O2 adding modes,aeration in leachate,different light sources and COD initial concentration in leachate.The results are as follows:rotating reactor has a maximum COD removal rate,however,falling film reactor is useful in projects due to its structure easy and its light source no dirty in spite of its sl... |
