| 摘 要： | 为解决ZVI(零价铁)电极表面的钝化问题,实现anammox(厌氧氨氧化)工艺稳定、高效地运行,采用EEZVI-UASB(电增强零价铁-升流式厌氧污泥床)技术处理养猪废水,研究了EEZVI电极电压、ρ(CODCr)及脱氮贡献率的相关性.结果表明,在温度为(35±1)℃、p H为6.80~7.10、电极电压为0.60 V的条件下,EEZVI-UASB对NH4+-N和NO2--N的去除率均维持在较高的水平;NH4+-N去除率90.00%,NO2--N去除率96.00%,TN平均去除率90.00%.当EEZVI电极电压为0.60 V时,AAOB(厌氧氨氧化菌)的活性为91.10 mg/(g·d)(以NH4+-N计);EEZVI-UASB中的优势功能菌主要为Pseudomonas属,其菌属16S r DNA的PCR扩增相似性达97%;系统中同时存在着反硝化、anammox、甲烷化等反应;其中anammox占主导作用,其对TN去除率的贡献率为54.10%~93.30%,反硝化及其他反应对TN去除率的贡献率为6.70%~45.90%.
