摘　　要：为解析工艺运行过程中氨氧化能力和硝化能力变化的原因,研究了冬季活性炭层上微生物的硝化性能。结果表明,在冬季,当有机碳浓度不高、溶解氧充足时,活性炭层对氨氮的去除率达到34%,0.3、0.8、1.3、1.6 m处(自上而下)的炭层对氨氮的平均去除率分别为5.2%、8.3%、11.5%、8.8%。不同活性炭层上的生物量差别不是太大,均值为17.1×108个E.coli/g活性炭。亚硝化菌、硝化菌占细菌总数的比例较大,已成为优势种群。To analyze the reasons for the variations of ammonia oxidation and nitrification ability of the process, the nitrification performance of microorganisms on activated carbon beds in winter was stud- ied. The results show that the total removal rate of NH4＋ - N is 34% and its different removal rates at 0.3 m, 0.8 m, 1.3 m and 1.6 m are 5.2% , 8.3% , 11.5% and 8.8% respectively owing to the sufficient dissolved oxygen and low TOC. Biomass on different activated carbon beds is approximate and its average value is about 17.1 ×10^8 E. coli/g. The ratios of nitrosobacteria and nitrobacteria in total bacteria are rather high, which become the dominant community in the system.
