摘　　要：采用紫外线消毒技术对城市污水再生水进行了消毒试验。结果表明,在试验条件下,当紫外线照射时间>5.6 s时,消毒后再生水的总大肠菌群指标能够满足《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)的要求;当紫外线照射时间>7.5 s时,总大肠菌群的光复活和暗复活能力都丧失。由此证明,在再生水处理中采用紫外线消毒是可行的。UV disinfection device was used for advanced treatment of reclaimed wastewater. The results show that when the irradiation time is more than 5.6 s, the total coliform bacteria in the disinfected wastewater meet the requirement of Reuse of Urban Recycling Water--Water Quality Standard for Ur- ban Miscellaneous Water Consumption （GB/T 18920 -2002 ）. When the irradiation time is more than 7.5 s, the photoreactivation and dark repair of the total coliform bacteria can be controlled. It is conclu- ded that UV disinfection is feasible in reclaimed wastewater treatment.
