| 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。

| Abstract: | 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 studied.The results show that the total removal rate of NH+4-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... |
