摘　　要：采用灰色关联分析理论 ,阐述了生物流化床工艺处理生活污水实验的灰色关联分析方法 ,给出了其算法并编制了相关的程序 .对实验中的主要条件 :填料填充量、水力停留时间及污泥回流比对污水COD、NH3 N去除率的影响程度进行了研究 ,结果表明各因素的影响强弱顺序依次为 :水力停留时间 >污泥回流比 >填料填充量 .Based on the gray system theory,the method of gray relationship matrix was used to analyze the experiment data of biological fluidized bed reactor.The algorithm was given with the computer program.The effects of filler level\,HRT and sludge return ratio on COD and NH\-3\|N removal ratios were investigated.The results showed that the decreasing effect sequence of the three factors is:HRT>sludge return ratio>filler level.This method is significant to the practical operation of biological fluidized bed reactor.
