为了确定季节变化对去除氨氮和有机碳污染物的水温和水质的潜在影响，并表征微生物特征的变化，中试规模的活性炭过滤器与异养硝化细菌生物强化进行了528天的研究。结果表明，生物强化活性炭（BEAC）反应器对氨氮和溶解性有机碳的去除率分别为69.2 ± 28.6%和23.1 ± 11.6%。结果表明，较高的可生物降解的溶解有机碳增强铵的去除，即使在低温下。BEAC反应器消耗的C/N比达到稳定值（即，3.3)经过2个月的运营。尽管季节性波动和土著社区的竞争，异养硝化细菌（Acinetoarthritis sp.）HRBLi 16和哈尔滨不动杆菌HITLi 7）相对稳定。碳源的量是最重要的环境参数，并显着影响微生物群落组成的BEAC反应器。本研究为BEAC反应器在饮用水除铵中的应用提供了新的见解，抵抗强烈的季节性变化。
To determine the potential effects of seasonal changes on water temperature and water quality upon removal of ammonium and organic carbon pollutants and to characterize the variations in microbial characteristics, a pilot-scale activated carbon filter biologically enhanced with heterotrophic nitrifying bacteria was investigated for 528 days. The results show that 69.2 ± 28.6% of ammonium and 23.1 ± 11.6% of the dissolved organic carbon were removed by the biologically enhanced activated carbon (BEAC) reactor. It is shown that higher biodegradable dissolved organic carbon enhances ammonium removal, even at low temperatures. The C/N ratio consumed by the BEAC reactor reached a steady value (i.e., 3.3) after 2 months of operation. Despite seasonal fluctuations and competition of the indigenous community, the heterotrophic nitrifying bacteria (Acinetobactersp. HRBLi 16 andAcinetobacter harbinensisstrain HITLi 7) remained relatively stable. The amount of carbon source was the most significant environmental parameter and dramatically affected the microbial community compositions in the BEAC reactor. The present study provides new insights into the application of a BEAC reactor for ammonium removal from drinking water, resisting strong seasonal changes.
