紫外线消毒后微生物的光复活特性及其评价方法

随着紫外线消毒技术应用的日益广泛,污水紫外线消毒后微生物的光复活特性值得关注。文章综述了光复活的机理、具有光复活能力的微生物种类、影响光复活的因素以及光复活的评价方式等,以期为系统研究光复活提供参考。具有复活能力的微生物种类较多,主要和体内所含光复活酶相关。影响光复活的因素涉及微生物、污水特性、紫外线系统及光复活条件四方面。评价光复活的方式至今没有统一标准。光复活及其对污水消毒的影响有待进一步深入研究。

Photoreactivation Characteristics and Its Evaluation Method after UV Disinfection

Attentions should be paid to photoreactivation in wastewater disinfection with UV technology as the technology is widely applied.Mechanism,microorganisms with photoreactivation capability,affecting factors and evaluation methods of photoreactivation were reviewed, hoping to offer a reference for deep and systematic study on photoreactivation.Microorganisms with photoreactivation enzyme had the ability of photoreactivation which was affected by microorganisms, characteristics of wastewater,UV system and phot...
