水和人们的生活生产密切相关,是非常重要的一个问题。我们国家的水资源相对来说是比较匮乏的,人均水资源拥有量只为世界平均值的四分之一。在建筑住宅排水系统中建设中水系统,不但可以节约用水,并且可以一定程度防止水体污染。因此,合理设计中水系统是节省资源和能源的关键。在此针对不同功能的建筑探讨不同的节水对策和技术。 Water and the production of people’s lives are closely related, is a very important issue. The water resources of our country are relatively scarce, with the per capita water resources holding only one quarter of the world average. In the construction of residential drainage system in the construction of water systems, not only can save water, and to a certain extent, prevent water pollution. Therefore, the rational design of the water system is the key to saving resources and energy. Here for different functions of the building to explore different water-saving measures and technologies.
