| 摘 要： | 为推进厌氧氨氧化技术应用于城市污水处理,耦合亚硝化系统和厌氧氨氧化系统,并在其前端添加ABR除碳系统,构建ABR除碳-亚硝化耦合厌氧氨氧化工艺进行城市污水脱氮除碳,采用MiSeq高通量测序技术分析污泥中微生物菌群结构的变化情况.结果表明,ABR除碳系统出水COD平均浓度120 mg·L~(-1),不会对后续亚硝化系统和厌氧氨氧化系统产生不利影响,控制亚硝化系统出水和ABR除碳出水比例为2∶1作为厌氧氨氧化系统进水,满足ANAMMOX所需NO_2~--N和NH_4~+-N基质比1∶1左右的要求.一体式反应器总氮去除率在86%～92%,出水COD浓度在20～40 mg·L~(-1).同时,实验后亚硝化系统中与反硝化作用密切相关的γ-Protebacteria纲有所增加,厌氧氨氧化系统中具有较高微生物生长速率和增强脱氮速率功能的Sphingobacteria纲显著增加,ABR除碳-亚硝化耦合厌氧氨氧化工艺能够有效用于处理城市污水脱氮除碳.
