摘　　要：BOD5/CODCr比值法是目前判断废水可生化性应用最多、最广泛的方法,其简单易行。但某些情况下,由于检测误差或检测环境与实际条件不一致,极易造成误判,如接种污泥未经驯化、水样进行稀释、pH调节操作、溶氧瓶环境差异等。笔者结合工程中所遇到的实例,对可能出现的偏差情况进行了归纳总结,以期起到预警的作用,同时就采用B/C法判断废水可生化性的科学严谨性提出了一些补充建议。BOD5/CODCr method is the most widely used method to determine the biodegradability of wastewater.However,in some cases,due to testing errors or inconsistencies between testing environment and actual conditions,misjudgment is easily caused,such as unacclimated inoculation sludge,dilution of water samples,PH adjustment operation,and differences in dissolved oxygen bottle environment.Combined with the examples encountered in the project,the author summarizes the possible deviations,in order to play an early warning role,and puts forward some supplementary Suggestions on the scientific seriousness of using B/C method to judge the biodegradability of wastewater.
