雨水回收利用概述

The Reclamation of Rain Water

随着城市化的迅速发展,道路、建筑群等不透水面积日益扩大。一方面雨水不能再补充地下水,加上地下水严重超采,使城市周围的水环境和生态环境恶化;另一方面大雨时,径流迅速汇集造成地面积水和城市局部洪灾。如果在城市建设中,注意发展雨水收集和利用工程,既增加了水资源,也是节约自来水的好措施,同时,通过雨水收集利用的广泛开展也有效缓解了上述问题。文章对雨水回收利用优点、经济效益、应用领域、具体的工艺流程并结合相关案例进行了系统的介绍。

With the rapid development of urbanization,roads,buildings and other impervious area is growing. On the one hand,the rain is not able to replenish groundwater,and the serious exploitation in above quota of groundwater,make the city surrounding water environment and ecological environment deterioration; On the other hand,when the heavy rain,caused the ground water runoff together quickly and urban local flooding. If in city construction,pay attention to the development of rainwater collection and use of engineering,both increased the water resources,is also a good measure of saving water,at the same time,through the rainwater collection and utilization of extensive and effective in relieving the above problems. Articles of rainwater recycling advantages and economic benefit,application field,concrete process flow and combining with related cases were introduced.
