Excilamps as modern mercury-free sources of narrow-band UV radiation represent an attractive alternative in environmental applications. This review focuses on recent studies on the water and surface decontamination with excilamps by means of direct photolysis and advanced oxidation processes. To date, direct photolysis and advanced oxidation processes (AOPs) such as UV/H(2)O(2), UV/Fenton and UV/O(3) have been applied for degradation of organic compounds (mainly, phenols, dyes and herbicides) in model aqueous solutions. Special emphasis is placed on studies combining UV irradiation (as a pre-treatment or post-treatment step) with biological treatment. In this review, the efficiencies of direct UV, UV/H(2)O(2) and UV/TiO(2) processes for inactivation of a variety of pathogenic microorganisms in water and on surfaces are discussed. The analysis of the literature shows that more works need to be done on scaling up the processes, degradation/mineralization of target pollutant(s) in real effluents and evaluation of energy requirements.
作为现代无汞窄带紫外线辐射源， excilamps 在环境应用中是一种很有吸引力的替代品。本综述重点介绍了最近关于 excilamps 通过直接光解和高级氧化工艺进行水和表面去污的研究。迄今为止，直接光解和高级氧化工艺（如 UV/H(2)O(2)、UV/Fenton 和 UV/O(3)）已被应用于模型水溶液中有机化合物（主要是酚类、染料和除草剂）的降解。特别强调了将紫外线照射（作为预处理或后处理步骤）与生物处理相结合的研究。在这篇综述中，讨论了直接 UV、UV/H(2)O(2)和 UV/TiO(2)工艺对水中和表面各种病原体微生物的灭活效率。对文献的分析表明，需要在扩大工艺规模、在实际废水中降解/矿化目标污染物以及评估能源需求方面做更多的工作。
