摘要: 通过对实验室SBR的四种运行方式的研究比较发现，进水阶段的长短、曝气方式对活性污泥的剩余污泥量和污泥性能（如SVI）都有影响。分级曝气方式下，反应器的污泥产率明显小，而短时进水方式下，反应器的污泥性能最佳。这对通过调整运行方式来减少剩余污泥量或改善污泥性能有一定意义。

Abstract: Comparisons among four operations of bench-scale SBRs show that feeding time and aeration mode do have impact on sludge yield and characteristics (e.g. SVI）. Sludge yield in SBR under operation of step-aeration is obviously low and sludge in SBR under operation of instant feeding is distinguished with good settleability. The findings are important to sludge quality improvement and excess sludge reduction through operation variation of activated sludge processes.

Key words: Operation mode, Aeration, Sludge yield
