我国目前年缺水达350亿m3。节水已经成为当下热议的话题,谈起节水,我们并不能简单地认为就是减少用水量。所谓节水,应当是在满足使用要求和给排水系统正常运行的前提下,加强管理,依靠科技进步,采取先进措施,提高水的有效利用率,减少无用耗水量。无用耗水量是对水资源的巨大浪费,会给十分紧张的城市供水带来更大困难。本文作者先从建筑给排水的浪费原因,并就建筑给排水中节水节能措施的应用加以分析,以期参考交流。
At present, our country has a water shortage of 35 billion m3. Saving water has become the hot topic of the moment. Speaking of water conservation, we can not simply think of it as reducing water consumption. The so-called water-saving should be to meet the requirements and the normal operation of the water supply and drainage system under the premise of strengthening management, relying on scientific and technological progress, to take advanced measures to improve the effective utilization of water and reduce useless water consumption. Useless water consumption is a huge waste of water resources, will bring great difficulties to the very tight urban water supply. The author firstly analyzes the causes of waste of water supply and drainage in buildings and analyzes the application of water-saving and energy-saving measures in building water supply and drainage so as to make reference and exchange.
