Abstract

The accumulation of antibiotics in river watersheds and lakes would induce spread of antibiotic resistance genes in drinking water. For the mineralization of sulfadiazine (SD), •OH equipment was installed in a drinking water treatment system with a capacity of 500 m3/h. The •OH was produced by strong ionization discharge combined with water jet cavitation. During the transfer of algae bloom water, in only 20 s, a dose of 1.0 mg/L and 0.5 mg/L •OH completely degraded the SD after coagulation sedimentation and sand filtration, respectively. All algae bloom was inactivated by disinfection with 0.5 mg/L •OH; the 106 drinking water quality indexes satisfied the Chinese Standards; and disinfection by-products, such as bromate was not formed. Based on NaClO disinfection, the total THM content increased to 188 µg/L, which is 2.35 times higher than the concentration limit regulated by United States Environmental Protection Agency (80 µg/ L). Advanced •OH oxidation based on strong ionization discharge can be used to completely mineralize antibiotics during drinking water treatment.
