| Zusammenfassung: | The invention provides a method and equipment for removing resistant bacteria and resistant genes in sewage, the resistant bacteria and the resistant genes in the sewage are removed through a UV/Fe (III)/coprecipitation method, that is, the bacteria are inactivated and the resistant genes are destroyed through ultraviolet irradiation and hydroxyl free radicals generated by an Fe (III) aqueous solution excited by ultraviolet light, and meanwhile, through a coagulation-precipitation process of Fe < 3 + >, the resistant bacteria and the resistant genes in the sewage are removed. Free bacteria, suspended particulate matters, organic matters and free resistance genes in a water body are removed in an enhanced manner, and the purpose of efficiently removing resistance in sewage in a broad spectrum manner is achieved. Resuscitation and regeneration of resistant bacteria and regeneration of resistant genes are effectively inhibited, and water environment safety of a sewage drainage receiving water body and human life |
