A Fenton-like disinfection process was conducted with Fenton's reagent (H2O2) at pH 3 or 5 on autochthonous drinking water biofilms grown on corroded or non-corroded pipe material. The biofilm disinfection by Fenton-like oxidation was limited by the low content of iron and copper in the biomass grown on non-corroded plumbing. It was slightly improved by spiking the distribution system with some additional iron source (soluble iron II or ferrihydrite particles appeared as interesting candidates). However successful in situ disinfection of biofilms was only achieved in fully corroded cast iron pipes using H2O2 and adjusting the pH to 5. These new results provide additional support for the use of Fenton's processes for cleaning drinking water distribution systems contaminated with biological agents or organics.
采用 Fenton 试剂（H2O2）在 pH 值为 3 或 5 的条件下对生长在腐蚀或非腐蚀管道材料上的土著饮用水生物膜进行芬顿样消毒处理。Fenton 样氧化对生物膜的消毒受到非腐蚀管道生物量中铁和铜含量低的限制，通过向配水系统中投加一些额外的铁源（可溶性铁 II 或铁氢氧化物颗粒似乎是很有前途的候选物）略有改善。然而，仅在用 H2O2 调节 pH 值至 5 的情况下，在完全腐蚀的铸铁管中才能成功地对生物膜进行原位消毒。这些新的结果为使用芬顿工艺清洁受生物剂或有机物污染的饮用水配水系统提供了更多的支持。
