摘　　要：对生物活性炭滤池启动运行中微生物生物量、生物活性、代谢功能及水质指标的变化情况进行连续分析.结果表明,生物活性炭滤池中异养微生物的平板计数生物量变化呈"S"形曲线,与微生物生长规律相符合,这反映滤池中微生物群落有明显的适应期、对数期和稳定期等生长阶段.脱氢酶活性随挂膜时间延长不断增加,第30天后达到稳定水平.滤池中微生物群落碳源代谢能力随挂膜时间的推进而增强,第40天时微生物群落的丰富度指数和Shannon多样性指数达到相对稳定值.氨氮(NH4+-N)与高锰酸盐指数(CODMn)去除率经过降低—缓慢上升—稳定的变化过程后,在第40天时去除率分别达到80%和28%左右.滤池启动运行29 d后溶解氧(DO)消耗率基本稳定,其值为18%.因此,在生物活性炭滤池挂膜过程中,分析微生物生长代谢与水质的变化特征可判断挂膜启动过程是否完成.The biomass, biological activity and metabolic function of microorganisms, and water quality parameters were monitored at the start-up stage of biological activated carbon filter with natural biofilm colonization. The results demonstrated that variation in heterotrophic plate counts liked S-curve at the start-up time in biological activated carbon filter, similar to the tendency of microbial growth. Namely, the development of microbial community in the filter had obviously lag phase, exponential phase, and stationary phase, etc. Activity of dehydrogenase gradually increased within 30 days of start-up process, then reached a plateau. The metabolic function of microbial community in the filter tended to increase over the start-up process, the richness and Shannon diversity indices got to a relatively stable level on 40th day. After a change process of decrease—slight increase—stability, the removal rate of NH4＋-N and CODMn were about 80% and 28% on 40th day, respectively. The consumption rate of dissolved oxygen remained steady after 29 days, and stayed at about 18%. The detection of growth and metabolism of microorganisms and water quality may help judge whether the biofilm is mature or not during the process of biofilm colonization. Fig 6, Tab 1, Ref 22
