摘　　要：研究了臭氧水的稳定性及对耐酸耐热菌的杀菌效果。分别进行中和剂试验、悬液杀菌试验和载体模拟验证,研究结果表明:浓度为31.1mg/L的臭氧水对耐酸耐热菌作用15min,其杀菌率达99.96%,并对载体表面的耐热菌有很好的杀灭作用。The stability of ozone in water and its sterilizing effect on Alicyclobacillus and Thermphillus are investigated. Emphases are put on sterilization tests by using blowing ozone water and ozonized water at different concentrations. The results are validated by simulated sterilization using Alicyclobacillus and Thermphillus inoculated glasses and show that ozone water at a concentration of 31mg/L can kill 99.96% of Alicyclobacillus and Thermphillus in 15 min.
