| 摘 要： | 水在贮蓄装置中的停留时间和流动特性是生活饮用水二次污染的主要原因，水在蓄贮装置中的停留时间越长，水中污染物质量浓度越高；水的流动性越差，水中微生物繁殖越快，为避免水质二次污染，应严格控制停留时间，消除死水区。

| Abstract: | The exit age and hydraulical character of water in cistern are the main reasons for water second pollution. The contaminants in water increase with the water exit age in cistern. Water mobility obviously affects the index of microbiology in water, and microorganisms in water breed with poor mobility. And motionless part water in cistern should be eliminated, and the water should be kept flowing. |

| Keywords: | drinking water cistern retention period mobility second pollution |
