二次供水技术及方案比选

Scheme Comparison and Selection of Secondary Water Supply Technologies

从能耗、供水安全、水质保障以及投资和运行费用等方面对常用二次供水方式进行了技术经济分析,论述了高层供水的压力分区以及低位蓄水池、高位蓄水池、中间水箱设置的优缺点,推荐采用市政供水管网→工频泵→高位水箱→用户的二次供水方式。

The techno-economic analysis of common secondary water supply modes was made in the aspects of energy consumption, water supply security, water quality guarantee, investment and operation cost. The pressure division of water supply for high-rise buildings as well as the advantage and disadvantage of setting low level water storage tank, high level water storage tank and intermediate water tank were discussed. The secondary water supply mode of municipal network→power frequency pump→high water storage tank→user was recommended.
