摘　　要：在对目前国内外再生水中病原菌指示微生物进行调研的基础上,结合再生水厂运行数据对再生水中病原菌指示微生物及其限值进行了探讨。研究结果表明,以粪大肠菌群作为再生水病原菌指示微生物更能够反映出水体中病原菌的存在状况,目前的再生水处理和消毒技术要达到《城市污水再生利用城市杂用水水质》(GB/T 18920—2002)对总大肠菌群≤3个/L的要求需要投加大量的消毒剂,增加了再生水的处理成本以及再生水中的消毒副产物。Based on the current home and abroad study of pathogenic bacteria microbiological indicators for reclaimed water,this paper discussed the pathogenic bacteria microbiological indicators in reclaimed water and their limitations according to the operation data from reclaimed water plant.The results showed： as a pathogenic bacteria microbiological indicator,fecal coliform could reflect the pathogenic bacteria existing situation in reclaimed water better;using current reclaimed water treatment and disinfection technologies,huge disinfection dosage was needed to satisfy the requirement of less than 3 unit/L total coliforms from ＂The reuse of urban recycling water—Water quality standard for urban miscellaneous water consumption（GB/T 18920—2002）＂,which would increase the cost of reclaimed water treatment and the amount of disinfection by-products.
