摘　　要：目的研究超声波联合臭氧用于医院污水消毒效果。方法采用理化分析和水体杀菌试验方法,对该超声波联合臭氧装置消毒污水的效果进行了观察。结果该超声波臭氧联合消毒装置产臭氧量为1 000 mg/h。在超声波输出功率为125 W、臭氧浓度维持在0.05 mg/L条件下,作用18 min,对污水中自然菌平均杀灭率达到99%。该装置随超声波输出功率增加,或臭氧浓度提高,其杀菌作用都会增强。结论该超声波臭氧联合装置对医疗污水中细菌具有一定杀灭作用,具有进一步应用研究价值。Objective To investigate the disinfection effect on hospital wastewater using ultrasound combined with O3.Methods Physico-chemical analysis and water quantitative germicidal test were used to observe the disinfection effect of ultrasound combined with O3.Results The total output O3 of the experimental set-up was 1 000 mg/h.The average killing rate of natural bacteria in waste water exposed to O3 0.05 mg/L for 18 min when the acoustic power was 125 W reached 99%.The disinfection effect could be improved with the increasing of the acoustic power and the concentration of O3.Conclusion The device using ultrasound combined with O3 is effective for hospital wastewater disinfection.So it is valuable for further study.
