| 摘 要： | 低温下(甚至低于1℃)异养细菌生物量仍能大量增加，但生物量的增加受生物可利用有机基质浓度的限制。虽然氨氮浓度不是曝气生物滤池内硝化细菌生物量增加的限制因子，但硝化细菌生物量的增加仍受低温的严重限制。低温对硝化细菌生物量增加比异养细菌生物量增加的限制作用更显著。

| Abstract: | The changes of attached heterotrophic and nitrifying biomass in biological aerated filter (BAF) at low temperatures were investigated.
At low water temperatures, even below 1℃, heterotrophic biomass could incre
ase greatly, however, the increase was inhibited by the availability of biodegradable organic substrate. For nitrifying biomass in BAF the ammonia concentration was not inhibitory, but its increase was seriously hampered by low temperature. The inhibitory effect of low temperature on nitrifying biomass was more pronounced
than that on heterotrophic biomass. |
