| 摘 要： | 美国现存供水管网系统的管径是按照消防用水最大流量确定的.由于现在火灾频率已变得很低,使得管网流速变缓,导致供水被输送到用户端时水质下降、甚至恶化.为此,美国已开始倡导并应用分用途供水的双管道供水系统,以小管径的不锈钢管输送直饮水,并保留传统管道作为消防等非饮用水之用.这样不仅可以达到供应直饮水的目的,而且可大大降低非饮用水的处理成本.另外,中水也可纳入传统管道系统,使分用途供水第二条管道铺设成本有所降低. |

| Abstract: | Conventional water supply pipeline system in United States was sized to satisfy the need of fire control with large flows.Due to low frequencies of fire as a disaster,slow water flow velocities are often caused in the conventional system now,which results in poor water qualities at the user ends.For this reason,America proposes dual water supply systems:a small stainless pipeline for drinking water and another large pipeline(the conventional system) for non-drinking system mainly for fighting fire.In this w... |
