摘要：

Antibiotic resistant bacteria (ARB) and antibiotic resistant gene (ARG), which pose great threaten to human health and ecological environment safety, have been widely recognized as new type of environmental pollutants. The microwave-enhanced photolysis process (MW/UV) was applied for the rifampicin resistant bacteria (RRB) disinfection in this paper. The effects of microwave power, irradiation time, initial concentration and pH of RRB were investigated, and the reactivation of the disinfected RRB in lake water, sea water and tap water was also studied. The RRB (40 mL, 3.8x10(7) CFU/mL, pH = 7) disinfection rate could reach 100% after 60 s irradiation of 500 W microwave and 18.54 mW/cm(2) UV light. However, the RRB after MW/UV disinfection all experienced reactivation when discharged into the actual water matrices. The reactivation rate followed the sequence: Lake water > Sea water> Tap water. Results revealed that the MW/UV process was an effective RRB disinfection method, but further research on the change of rifampicin resistant genes in the MW/UV process was urgently needed.
