摘要:
构建缺氧-好氧-缺氧/序批式固定生物膜耦合活性污泥反应器（AOA-SBFASR），对城市污水开展中试处理研究，考察了该反应器的深度脱氮效果，并对系统中微生物种类和氮代谢通路进行分析。结果表明，AOA-SBFASR工艺可以高效去除污水中的COD、NH4+-N和TN，去除率分别可达到92.55%、98.75%和75.64%；在55 d内微生物群落结构发生了演替，硝化细菌、反硝化细菌和能降解难降解有机物的细菌相对丰度增加；氨氮主要通过完全硝化过程被去除，硝态氮主要通过反硝化和异化硝酸盐还原过程被去除。
Abstract:
The anoxic-oxic-anoxic sequencing batch fixed biofilm coupled activated sludge reactor (AOA-SBFASR) was constructed for a pilot study on the treatment of municipal wastewater. The advanced nitrogen removal efficacy of the reactor was investigated, while the microbial communities as well as the nitrogen metabolism pathways within the system were analyzed. The AOA-SBFASR process demonstrated significant efficacy in the removal of COD, NH4+-N, and TN from wastewater, achieving removal efficiencies of 92.55%, 98.75%, and 75.64%, respectively. Within a period of 55 days, the microbial community composition underwent significant changes, with an observed increase in the relative abundance of nitrifying bacteria, denitrifying bacteria, and microorganisms capable of degrading refractory organic matters. Ammonia nitrogen was primarily eliminated through the complete nitrification process, while nitrate nitrogen was predominantly removed via denitrification and dissimilatory nitrate reduction processes.
