| 摘 要： | 药物和个人护理用品(PPCPs)是最近十年引起关注的一类新型有机微量污染物,其对人类健康和生态环境安全的影响受到了越来越多的关注.传统的给水处理和污水处理工艺都不能有效去除水中的PPCPs,因此有必要采用臭氧氧化、高级氧化等工艺进行深度处理.臭氧是选择性氧化剂,其与PPCPs的反应受PPCPs的基团电子特性和溶液pH的影响;高级氧化技术产生的羟基自由基·OH氧化能力强,与PPCPs的反应没有选择性,主要包括O_3/H_2O_2、UV/H_2O_2、UV/TiO_2、芬顿和光芬顿氧化等.这些深度处理工艺的采用受一些因素的限制,同种工艺或不同工艺的组合能达到更高的去除效率.

| Abstract: | Pharmaceuticals and personal care products(PPCPs)are a new type of organic micro-pollutants concerned in the recent decade. Their impact on human health and ecological environment safety receives more and more concerns. The conventional water and wastewater treatment technology can't remove the PPCPs effectively, so it is necessary to adopt ozonation, advanced oxidation for advanced treatment. Ozone is a selective oxidant, its reaction with PPCPs is influenced by the electrical characteristics of PPCPs and the pH of solution. The oxidbillity of hydroxyl radical is srong, which is generated by the advanced oxidation such as O_3/H_2O_2、UV/H_2O_2、UV/TiO_2 、Fenton and photo-Fenton. There is no selectivity when hydroxyl radical reacts with PPCPs. The adoption of advanced treatment has some limitation, and the combination of the same or different technology can achieve higher removal efficiency. |
