民用建筑生活给水系统水质保障设计探讨

Discussion on the water quality guarantee of domestic water supply system in civil buildings

合理的供水设施规模以及提高管网内水的流动性是保障建筑室内饮用水水质的有效措施。结合两个工程案例,指出了较高的管道流速有利于控制供水管网管道容积,建议水池补水采用多级可调模式以应对给水系统低负荷运行状态,通过采用末端自动定时放水装置避免管网长时间滞水。

Reasonable scale of water supply facilities and improvement of water flow in the pipe network are effective measures to ensure the quality of drinking water in the buildings.Combined with two engineering cases,it is pointed out that higher pipeline flow rate is beneficial to control the scale of water supply network.It is suggested that the multi-stage adjustable mode should be adopted for the water supplement of the tank to cope with the low load operation state of the water supply system,and the Automatic end timing water discharge devices should be used to avoid the long-term water stagnation of the network.
