摘要
国内许多城市都将取消高位水箱供水方式,并以叠压(无负压)供水方式取而代之。针对叠压(无负压)供水和高位水箱供水两种方式进行水质调研,对比分析两种供水方式的水质安全性。分析得出:高位水箱供水方式经过良好的维护管理,具有与叠压(无负压)供水方式相同的水质安全性。建议在解决二次供水污染问题时结合建筑现状条件,理性选择二次供水技术。
Many cities in China abolish water supply system with head tank and replace it with pressure-superposed water supply, which is also called non-negative pressure water supply. This paper investigated water qualities of water supply systems with pressure-superposed and head tank, and then compared and analyzed the water quality safety of two kinds of water supply methods. The results showed that： Through better maintenance and management, the water supply with head water tank had the same water quality safety as pressure-superposed water supply. It was suggested that the secondary water supply technologies should be chosen rationally according to the condition of building when solving the water pollution problems caused by secondary water supply.
