紫外线辐照细菌光复活相关干预因素研究进展

A Review on the Research in Intervention Factors of Photoreactivation after Ultraviolet Disinfection

紫外线（UV）消毒在污水处理等领域发挥着重大作用,但其消毒效果受到细菌光复活的制约。从5个方面,包括UV消毒条件、光复活条件、细菌自身差异、污水理化性质以及是否联合化学消毒法等因素,介绍了当前国内外对于细菌光复活干预因素的研究进展,旨在为UV消毒的高效应用提供指导参考。分析了光复活的研究前景。

Ultraviolet （UV） disinfection plays a significant role in wastewater treatment whilst being restricted by the existence of photoreactivation. Aimed at providing reliable guidance for efficient application of UV disinfection, intervention factors of bacteria photoreactivation were introduced based on the research status home and abroad currently. There were five aspects involved including conditions of UV disinfection, factors of photoreactivation, differences of bacteria, physico-chemical properties of sewage, and whether combined with chemical disinfection or not. Besides, the perspective of the future study in photoreactivation was analysed as well.
