高层建筑管道直饮水工程实践

Practice in design of the drinking water taken directly from supply pipe for a high-rise building

介绍了反渗透(RO)工艺在高层建筑管道直饮水工程中的应用实践,探讨了有关的工艺过程、工艺参数和设备选型。采用恒压变频、分区减压阀双循环供水方式和臭氧、紫外线双重消毒,确保供水稳定、及时、安全。运行和测试结果表明:出水电导率≤10μs/cm,达到国家直饮净水水质标准,整套系统能全自动运行,并实现远程控制管理。

In this paper,the application of the reverse osmosis technique in the design of the drinking water taken directly from supply pipe for a highrise building is introduced. The technological process and parameters and the choosing of equipment are discussed. The drinking water is supplied under constant pressure with variable frequency,and subarea decompressors are adopted. And the water runs in dual cycle and is sterilized with ozone and ultraviolet radiation ao as to ensure the supplied water being steady,timely and safe. The operation and testing results show that the conductance of product water is equal to or less than 10 μs/cm,and the water reaches the State standards of the drinking water. The introduced system can operate automatically, and the longdistance control and supervision is realized.
