摘要:
以污水厂处理水为研究对象,采用铁基质生物载体与生物膜耦合实现高效自养反硝化脱氮。考察停留时间(HRT)对系统脱氮效能的影响,通过动力学及微生物群落结构分析,揭示耦合技术的脱氮机理。结果表明:HRT为8 h,对一级A和一级B污水厂处理水,总氮(TN)平均去除率分别为95.41%和92.55%,TN处理负荷分别为0.48 kg TN/(m3·d)和0.58 kg TN/(m3·d),硝化过程氨氮(NH4+-N)饱和常数分别为1.17 mg/L和0.72 mg/L,反硝化过程硝氮(NO3--N)饱和常数分别为0.87 mg/L和0.67 mg/L。出水水质分别达到《地表水环境质量标准》Ⅲ类、Ⅴ类水质标准。铁基质生物载体与生物膜耦合系统中微生物优势菌属为Maritimimonas、Rhodobacter和Sphaerotilus, 均为自养反硝化菌,证实了铁基质生物载体可为自养反硝化菌提供电子,实现生物自养反硝化脱氮。
