Comparative Analysis of the Mineralization of NOM by Using the VUV and H2O2/UV Processes 利用VUV和H2O2/UV过程对NOM矿化的对比分析
发布日期: 2009-11-01
从原水中去除天然有机物(NOM)有助于降低 消毒副产物(DBPs)的形成。NOM可以通过使用先进的技术进行矿化 氧化过程(AOP),如真空紫外辐射(VUV)、紫外辐射加H2O2 (H2O2/UV),或VUV辐射加H2O2(H2O2/VUV)过程。与 H2O2/UV过程表明,在处理原料后,可以实现42%的NOM矿化 180分钟的水样。 VUV观察到了更快的矿化速率 在120分钟的辐照后,提供90%的有机物矿化。 此外,在H2O2/VUV过程中获得了略大的矿化。整体 具有H2O2/UV、VUV和H2O2/VUV过程的NOM矿化的量子产率 分别为0.004、0.097和0.016。包括14个参考文献、图表。
The removal of natural organic matter (NOM) from raw water contributes to lower disinfection byproducts (DBPs) formation. NOM can be mineralized by using advanced oxidation processes (AOPs), such as vacuum-UV radiation (VUV), UV radiation plus H2O2 (H2O2/UV), or VUV radiation plus H2O2 (H2O2/VUV) processes. Experimental work with the H2O2/UV process showed that 42% mineralization of NOM could be achieved after treating raw water samples for 180 minutes. A much faster mineralization rate was observed with the VUV process, providing 90% mineralization of the organic matter after 120 minutes of irradiation. Also, a slightly greater mineralization was obtained with the H2O2/VUV process. The overall quantum yields of the NOM mineralization with the H2O2/UV, VUV, and H2O2/VUV processes were 0.004, 0.097, and 0.016, respectively. Includes 14 references, figures.
