Rainwater collection and treatment system used for roof of residential building
The invention discloses a rainwater collection and treatment system used for a roof of a residential building. The rainwater collection and treatment system comprises a pebble absorbing area, an overflow channel and a rainwater garden which are sequentially arranged on the ground beside the residential building from near to far, residential building roof rainwater is guided to the ground through adownpipe, the bottom of the downpipe is connected with an elbow, the elbow is connected with a water inlet of the pebble absorbing area, a water outlet of the pebble absorbing area is connected to the rainwater garden through the overflow channel; a water seepage ditch is arranged below the pebble absorbing area, a water seepage pipe used for leading the rainwater out to a basement top plate is arranged at the bottom of the water seepage ditch, a basement drainage layer is arranged at the top of the basement top plate, and the basement drainage layer is connected to a basement drainage ditch.According to the rainwater collection and treatment system used for the roof of the residential building, a flow-limiting purification facility is additionally arranged, so that purifying and temporarily retaining roof rainwater runoff are carried out, sometimes, storing the rainwater in a short time can be carried out, the time for the rainwater runoff to reach a rainwater pipe network is shortened, and therefore the peak flow is reduced, and the rainwater collection and treatment system is an efficient runoff conduction facility.
本发明公开了用于住宅楼屋顶雨水收集处理系统，其包括由近及远依次设置在住宅楼旁地面上的卵石消纳区、溢流通道和雨水花园，由落水管将住宅楼屋顶雨水引到地面，所述落水管的底部连接一弯头，所述弯头连接所述卵石消纳区的进水口，所述卵石消纳区的出水口通过所述溢流通道连接至所述雨水花园；所述卵石消纳区的下方设置有渗水沟，所述渗水沟的底部设置有用于将雨水引出至地库顶板上的渗水管，所述地库顶板的顶部设置有地库排水层，所述地库排水层连接至地库排水沟。本发明通过增加限流净化设施对屋顶雨水径流进行净化和临时滞留，有时会对雨水进行短时间的存储，减缓雨水径流到达雨水管网的时间，从而降低峰值流量，是一种高效的径流传导设施。
