摘　　要：污水再生利用的关键是水质安全保障和风险控制.微生物风险是再生水安全利用过程中需要优先控制的重要问题.本文系统探讨了我国现行污水再生利用标准中的病原微生物控制要求,分析了基于病原微生物指示指标浓度控制的必要性与不足,提出了引入微生物去除能力保障控制的必要性,并详细介绍了其制定方法与保障措施.今后,需进一步深入探讨基于浓度控制与保障能力控制相结合的污水再生利用微生物控制方法,以期为我国再生水安全利用提供技术支撑.The key to water reclamation and reuse is water quality safety insurance and risk control. Microbial risk control is an important issue that requires priority during the safe reuse of reclaimed water. This paper systematically summarizes the control requirements for microbial indicators in China’s current water reuse standards,focusing on the necessity and deficiencies of water quality targets and microbial indicator concentration control. The performance targets based on the removal requirements of microorganisms together with the methodology and implementation strategies are introduced in detail for the first time. In the future,it is necessary to further explore the microbial control method of water reclamation based on the combination of water quality targets and performance targets,which could provide support for the safe reuse of reclaimed water in China.
