摘　　要：生化需氧量是评价水质污染情况、水体自净能力的重要指标之一,它能够直接反映水体自净过程中的耗氧需求,也是评价污水处理及大环境修复成效的有力参数之一.然而,国标方法耗时长、误差大、数据滞后.快速检测方法发展四十余年,却鲜有应用.本文归纳总结了现有的快速生化需氧量检测的主要方法及缺陷,并根据本课题组二十余年的科研经历,详细论述了一种基于原位生长微生物膜反应器构建流通式生化需氧量在线监测的新原理、新方法、新仪器及其应用.Biochemical oxygen demand （BOD） is one of the most important parameters in estimating the water quality and its self-cleaning ability. It represented the oxygen demand in biochemical oxidation process in the wastewater treatment process and environmental repair. The standard method needs 5-day incubation, and the analytical error is very huge. Rapid determination proceeded over forty years, but few applications stand until now. In this article, the author concluded the developments of current rapid BOD determination methods and its drawbacks. A new BOD online determination method and analytical instrument based on natively cultivated plug-flow biofllm reactor was developed and applied in situ extensively.
