摘　　要：为了解饮水机中纯净水的微生物污染状况及变化规律 ,对现场使用的饮水机水中的细菌总数、大肠菌群、霉菌和酵母菌及消毒后纯净水中细菌总数变化进行检测。检测结果表明 ,饮水机纯净水细菌污染严重 ,并随着使用时间的增加 ,水中细菌总数不断增多。消毒剂可杀灭水中细菌 ,但无法在饮水机使用过程中有效地防止细菌污染和细菌生长。建议采取有效措施防止空气中微生物进入饮水机中 ,并选用合适的有机材料防止饮用水微生物生长 。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.
