  • Membrane fouling is a prominent problem that hinders the stable and efficient operation of reverse osmosis (RO) system for wastewater reclamation. Previous studies showed that chlorine disinfection, which was commonly used in RO system as the pretreatment could lead to significant change in microbial community structure and secretion characteristics, resulting in serious biofouling. In order to optimize the selection of pretreatment process for RO system in wastewater reclamation, the effect of ultraviolet (UV) disinfection on the growth, community structure and secretion characteristics of microorganism in reclaimed water was investigated. Results showed that when the UV dose was 20, 40 and 80 mJ/cm2, the inactivation rate of bacteria reached 1, 3 and 4 log, respectively. The lag period of bacterial growth was prolonged after UV disinfection. The biomass in stable period also decreased by 18.6% and 19.2% compared with the control group, when the UV dose was 40 and 80 mJ/cm2. The relative abundance of Proteobacteria phylum, Betaproteobacteria class and Janthinobacterium genus increased at higher UV dose (40, 80 mJ/cm2). In terms of secretion characteristics, the amount of extracellular polymeric substances (EPS) decreased firstly and then increased with the increase of UV dose, and the content of macromolecule substances in them increased after UV disinfection, showing higher potential of RO membrane fouling.
