RAPID START-UP AND MICROBIAL COMMUNITY ANALYSIS OF A SULFUR AUTOTROPHIC DENITRIFICATION COUPLED ANAEROBIC AMMONIA OXIDATION DENITRIFICATION SYSTEM

  • 摘要: 以硫代硫酸钠为电子供体,采用梯度增加基质负荷的方式,在SBR反应器中完成硫自养反硝化(SAD)工艺启动。通过接种厌氧氨氧化(Anammox)污泥,采用pH和NO-3-N/NH+4-N联合调控策略进行研究,实现硫自养反硝化耦合厌氧氨氧化(SAD/A)自养脱氮系统快速启动及稳定运行。结果表明:30 d成功将反硝化污泥驯化为SAD污泥,90 d后,SBR反应器成功富集SAD污泥,系统NO-3-N去除率可达到85%以上。SAD/A系统2种种泥最佳接种比为3∶1,运行14 d后SAD/A系统成功启动。30 d后,系统NO-3-N去除率可达到85%,NH+4-N去除率达到80%。pH值为8,且ρ(NO-3-N)/ρ(NH+4-N)为1.8时,耦合系统脱氮效率最佳,实现稳定运行。高通量测序结果表明:SAD/A系统整体的物种多样性和丰富度增加,优势微生物菌属为厌氧氨氧化菌属(Candidatus Brocadia)和硫杆菌属(Thiobacillus),二者相对丰度相近,系统耦合度较好。
