A Fenton-like reaction and anaerobic ammonium oxidation (anammox) were combined to construct a novel process named FenTaMox for removing nitrogen (N) and organic carbon (measured as chemical oxidation demand (COD)). Two columns were packed with iron-manganese-sepiolite, a catalyst that uses hydrogen peroxide (H2O2) to catalyze Fenton-like reactions, and inoculated with marine anammox bacteria. During the start-up, marine anammox medium was fed into both columns to acclimate the marine anammox bacteria to iron-manganese-sepiolite. Batch experiments revealed that the marine anammox bacteria were not affected by 60 mgL−1 of H2O2. Next, medium containing glucose and H2O2 was fed into one column as the FenTaMox treatment, while medium containing glucose but no H2O2 was fed into the other column as the control. At a COD/N of 4, FenTaMox exhibited higher removal efficiencies of N and COD compared with that of the control, suggesting the application of FenTaMox for organic carbon- and N- removal.

一种新颖的反应器,结合了厌氧氨氧化反应和类Fenton反应,可同时去除不同有机碳氮比的有机碳和氮。

结合Fenton样反应和厌氧铵氧化(anammox)来构建名为FenTaMox的新工艺,该工艺用于去除氮(N)和有机碳(以化学氧化需求(COD)衡量)。两根柱子装满铁锰海泡石(一种使用过氧化氢(H 2 O 2)催化Fenton样反应的催化剂),并接种了海洋厌氧菌。在启动过程中,将海洋厌氧菌培养基送入两个色谱柱中,以使海洋厌氧菌细菌适应铁锰海泡石。批处理实验表明,海洋厌氧菌不受60 mgL -1的H 2 O 2的影响。接下来,含有葡萄糖和H 2 O 2的培养基将其作为FenTaMox处理进料到一个塔中,而将含有葡萄糖但没有H 2 O 2的培养基进料到另一塔中作为对照。在COD / N为4时,与对照相比,FenTaMox表现出更高的N和COD去除效率,表明FenTaMox可用于有机碳和N去除。
