[Survey on the microbial pollution of pure water in water dispenser and its disinfection].
The counts of bacteria, total coliforms and fungi of pure water in the water dispensers were detected and the regular pattern of bacterial reproduction in water were studied after the dispensers and water were disinfected. The results showed the bacterial pollution in the water dispensers was serious and the bacteria counts increased with the time of using dispensers lasted. The disinfectant could killed effectively the bacteria in the water sources but it could not control the new bacteria polluted and reproduced while the water dispensers were in use. It was suggested that the bacteria polluted from air should be prevented by taking effective methods and selecting appropriate organic materials for making dispensers.
