城镇给水工程设计的节能主要从水量(Q)、水头(H)和效率(η)三个因素着眼,即要在满足用户的水量、水质和水压条件下,尽量减少水厂自身耗水量和漏损水量,降低各个环节的水头损失,减少无效水头以及提高各种设备的效率。本文就常规给水工程设计中如何节能的问题作一讨论。 1.合理布局节能从布局上入手是一个十分重要的环节,最大的能耗往往是系统方面的。目前我国县级以上的大中城市,绝大部分都有一个以上的水厂,对十个大中城市的统计表明,
The energy saving of urban water supply engineering design mainly focuses on the three factors of water quantity (Q), head (H) and efficiency (η), that is, to minimize the water consumption of the water plant itself while satisfying the user’s water quantity, water quality and water pressure conditions. Leakage of water, reduce the head loss of all aspects, reduce the invalid head and improve the efficiency of various equipment. This article discusses how to save energy in the design of conventional water supply projects. 1. Reasonable layout Energy-saving is a very important part to start with layout. The biggest energy consumption is often the system aspect. At present, most large and medium-sized cities above the county level in China have more than one water plant. Statistics on ten large and medium-sized cities indicate that
