摘　　要：用序批式反应器(SBR)研究了好氧颗粒在不同进水负荷条件下其内源衰减系数(Kd)与比耗氧速率(SOUR)的关系及其对出水水质的影响。结果表明Kd和SOUR均在高进水负荷条件下大,出水SS随着Kd的增大而增大,但出水NO3--N则随着Kd的增大而减小。It was investigated using sequencing batch reactors（SBR） with different salinities and organic loading rates（OLRs） the connection between Kd and SOUR for the influence of. water quality. It was found that the Kd and SOUR were high in high OLRs, and the yielding water SS increased with the increase of Kd, and the concentration of yielding water NO3^- - N decreased with the increase of Kd.
