为李解臭氧对二次供水的消毒效果,进行了悬液定量杀菌试验、结果,向1m3水中通入臭氧5min,水中个别点含臭氧0．36 mg/L,其余点为 0．010~0.014 mg/L;通入臭氧40min,水中含臭氧 0.025-0.038mg/L(个别点 0.46 mg/L)、向1m3水中通入臭氧 20 min,对水中大肠杆菌杀灭率达100%;通入臭氧120 min,对水中枯草杆菌黑色变种芽胞杀灭率为 90．18%-99.42%、向3m3水中通入臭氧30min,对水中自然菌杀灭率达100%。
As the solution of ozone on the secondary water disinfection effect, the suspension quantitative disinfection test, the results, to 1m3 of water into the ozone 5min, individual points of water containing ozone 0.36 mg / L, the rest 0.010 ~ 0.014 mg / L; the introduction of ozone 40min, the water containing ozone 0.025-0.038mg / L (individual point 0.46 mg / L), 1m3 water into the ozone 20 min, the killing rate of E. coli in water up to 100% 120 min, the killing rate of Bacillus subtilis black spores was 90.18% -99.42% in water, ozone was introduced into 3m3 water for 30 min, and the killing rate of natural bacteria in water reached 100%.
