摘　　要：生物活性炭(biological activated carbon, BAC)失效判定依据是目前饮用水处理领域关注的热点之一。针对水厂BAC失效判定过程中需要充分考虑的BAC功能定位、净化机理及作用过程、生物降解效能变化规律、生物降解副产物以及旧BAC资源化利用等方面进行了详细论述,结合需遵循的基本原则探讨了BAC失效判定的基本依据及其在实际水厂中实施的基本过程,并进一步给出了水厂日常管理中针对BAC进行“健康体检”的建议及操作方法。研究结果可为我国供水厂BAC的失效判定提供一定参考。Failure judgement of biological activated carbon(BAC) is one of hot topic in the field of drinking water treatment. According BAC failure determination process in WTPs, functional orientation, removal mechanism and process, variation law of biological degradation, byproduct of bio-degradation and re-utilization of spent BAC were expressed in detail. Combined with the basic principles to be followed, the basic basis of BAC failure determination and the basic process of its implementation in the actual WTP were discussed. In addition, the “physical examination” to the BAC in the practice of daily management of WTP was proposed preliminarily. The results can supply some reference for the WTPs which have BAC process at home.
