摘　　要：HK型臭氧水龙头可直接将产生的臭氧充入自来水,用化学测定法和载体定量法对其臭氧产量及杀菌作用进行了观察。结果,在水压3kg/cm^2、水温12℃条件下,以3.2、4.9、6.6L/min的水流量检测,水中臭氧含量分别为0.24、0.30、0.73 mg/L。以臭氧含量0.45 mg/L的流动水浸泡染有大肠杆菌的布片15 min,其杀灭率仅为97.25％,流动作用5 min水中自然菌减少50％,说明臭氧水龙头产生的臭氧对自来水有消毒作用。若臭氧水龙头与自来水管连接用于饮水消毒和水果蔬菜流动清洗,具有一定消毒作用。通过式臭氧饮水消毒器产生的臭氧水臭氧含量低,易分解,不宜作消毒液使用。HK-type ozone faucet can introduce the ozone produced directly into the tap water. Its ozone yield and germicidal efficacy were observed using the chemical measurement method and carrier quantitative method. The results showed that under conditions of water pressure 3 kg/ cm2, water temperature 12癈 and water flow rate 3.2, 4.9 and 6.6 L/ min, the ozone content in water was measured to be 0.24, 0.30 and 0.73 mg / L respectively. Immersing the cloth strip contaminated with Escherichia coli in the running water con-taining ozone 0.45 mg/ L for 15 min killed only 97.25% of the bacteria, and the natural bacteria in the run-ning water decreased by 50% in 5 min, indicating that the ozone produced by the ozone faucet had disinfection effect. If the ozone faucet is connected to the tap water pipe for disinfection of drinking water and washing fruits and vegetables, certain disinfection effect can be obtained. The ozone content of ozone water produced by ozone drinking water disinfector of passing-through type is low and is apt to decompose, so it is unsuitable to be used as liquid disinfectant.
