研究了浸没式生物滤池中微生物膜去除好氧BOD的吸氧特性。采用废气分析方法测定微生物膜的摄氧量，同时测定好氧BOD去除和内源呼吸的摄氧量。研究了给定有机底物的产氧量与细胞产氧量之间的关系。结果表明，去除生化需氧量的产氧量随细胞产氧量的增加而降低。随着微生物膜厚度的增加，微生物的内源呼吸显著降低，但产氧量变化不大。此外，在好氧条件下，由于微生物膜的过度生长而导致包装材料堵塞，阻碍了微生物的自降解。
The oxygen uptake characteristics of microbial film for aerobic BOD removal in a submerged biofilter was investigated. The oxygen uptake rate of the microbial film was determined by the off-gas analysis method, and the oxygen uptake for both aerobic BOD removal and endogenous respiration were determined. The relationship between oxygen yield and cell yield for a given organic substrate was investigated as well. It was shown that the oxygen yield for BOD removal decreased with an increase in cell yield. The oxygen yield was little changed while the endogenous respiration of microbes was significantly reduced with increased microbial film thickness. Moreover the self-degradation of microbes under aerobic conditions was hindered by clogging of packing materials due to excess growth of microbial film.
