【Abstract】 The germicidal efficacy of 5 types of ultraviolet disinfection apparatus for drinking water was evaluated in laboratory. The results indicated that all the 5 types of disinfection apparatus were effective in killing Escherichia coli, Staphylococcus albus and spore of Bacillus cereus. The killing rates were 99.2～100%, 99.95～100% and 99.80～100% respectively. If the disinfection apparatus is used in combination with filtration method, the result of disinfection of drinking water can be improved further.更多还原
