雨水集蓄工程一般由集雨系统、输水系统、净水系统、蓄水系统和提水设备组成。1、集雨系统顾名思义,集雨系统就是收集雨水的场地,因而也叫集雨场,主要包括集雨面、边坎两部分。(1)集雨面集雨面的主要作用是承接雨水,并使雨水产生地表径流,从而达到收集雨水的目的。常用的集雨面有屋顶、庭院、道路、农田、林地等。集雨面的面积大小主要根据当地的有效降水量、集雨场的集水性能、蓄水建筑物(水窖或蓄水池)的容积大小、蓄水建筑物的年重复利用率等因
Rainwater catchment project generally consists of rainwater harvesting system, water delivery system, water purification system, water storage system and water lifting equipment. Rainwater harvesting system As its name implies, rainwater harvesting system is the site of rainwater harvesting, so it is also called rainwater harvesting area, which mainly includes rainwater catchment and ridge. (1) Rain-collecting surface The main function of rain-collecting surface is to undertake the rainwater and make the rainwater run away from the surface so as to achieve the purpose of collecting rainwater. Rain-collecting surface commonly used roofs, courtyards, roads, farmland, woodland and so on. The area of the catchment surface is mainly determined by the effective precipitation in the area, the catchment performance of the catchment, the volume of the storage building (the size of the water cellar or reservoir) and the annual reutilization rate of the impoundment
