本研究主要研究在典型的饮用水处理条件下，天然有机物（NOM）对芳香族合成有机化学品五氯酚（PCP）生物降解的影响。在第一组实验中，四个色谱柱并联运行，并向PCP和NOM进料，使其暴露于no氧化、氯胺化、臭氧化或氯胺化和臭氧化。第二个实验考察了在没有NOM的情况下PCP的去除情况。在第一个实验中，氯胺和臭氧对NOM的去除效果最好。 在没有NOM的情况下，PCP的去除效果优于有NOM的情况。因此，NOM会干扰PCP的生物降解，但通过氧化剂处理NOM，干扰程度会降低。包括23个参考文献、表格和图表。

This research focused on the influence of naturally occurring organic matter (NOM) on the biodegradation of an aromatic synthetic organic chemical, pentachlorophenol (PCP), under conditions typical of drinking water treatment. In the first set of experiments, four columns were operated in parallel and were fed PCP and NOM exposed to no oxidation, chloramination, ozonation, or both chloramination and ozonation. The second experiment examined PCP removal in the absence of NOM. The best removal of PCP in the first experiments occurred for the NOM exposed to both chloramines and ozone. Removal of PCP in the absence of NOM was better than in the presence of NOM. Thus, NOM interfered with PCP biodegradation, but the degree of interference was diminished by treating the NOM with oxidants. Includes 23 references, tables, figures.
