Grey relationship matrix analysis for the experiment of treating domestic sewage with biological fluidized bed reactor
生物流化床工艺处理生活污水实验的灰色关联分析

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.
