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 photoreactivation condition.Since there is a lack of standard evaluation method of photoreactivation,the deep study of photoreactivation and its effect on wastewater disinfection is needed.
