  • 摘要: 采用高级氧化(advanced oxidation processes, AOPs)技术去除水体中的药物及个人护理品(PPCPs)污染物，选取PPCPs中的典型物质萘普生(NPX)为研究对象，探讨了其在UV/氯体系中的降解特性。结果表明：在UV/氯体系中，NPX的降解遵循拟一级动力学模型。氯剂量越高，溶液pH越低，越有利于NPX的降解；不同水基质种类对UV/氯工艺降解NPX的效果有不同影响，HCO3-和HA的存在抑制了NPX的降解，而Cl-的存在明显促进了NPX的降解。UV/氯工艺是一种行之有效的处理PPCPs的技术，但与直接氯氧化相比，UV/氯工艺会有生成更多消毒副产物的风险，需要在实际应用中加以注意。
    Abstract: Advanced oxidation processes (AOPs) were applied to remove pharmaceutical and personal care products(PPCPs) in water. In this study, naproxen (NPX), a typical PPCPs, was selected as the object contaminant, and its degradation characterization by UV/ chlorine was investigated. The results indicated that the degradation of NPX followed pseudo-first-order kinetics pattern in all cases, and the rate constants increased as the chlorine dose increased and the pH decreased. The effects of the water matrix on UV/chlorine process were species-dependent. Typically, the NPX degradation was inhibited in the presence of HCO3? and HA but obviously improved by the presence of Cl?. These results indicated that the UV/chlorine process is a promising technology for treating the PPCPs polluted water. However, UV/chlorine can notably enhance the formation of disinfection by-products compared to direct chlorination, which should be carefully considered when integrating such process into drinking water treatment schemes.
