Rainwater treatment device
The invention belongs to the field of water resource recovery, sponge city construction and rainwater management and control, and discloses a rainwater treatment device. The rainwater treatment device comprises a barrel, a filter cartridge and a valve plate mechanism; a vertically-arranged partition plate is arranged in the barrel and divides the barrel into an overflow chamber and a water inlet chamber; the overflow chamber is provided with a water outlet; the water inlet chamber is provided with a water inlet and a backflow opening, and the water inlet is positioned below the backflow opening; the filter cartridge is arranged in the overflow chamber; a water inlet of the filter cartridge communicates with the water inlet chamber, and a water outlet of the filter cartridge communicates with the water outlet; a gap is formed between the outer wall of the filter cartridge and the inner wall of the barrel, and the filter cartridge is used for filtering rainwater; and the valve plate mechanism is arranged in the water inlet chamber and used for closing the water inlet when the water level of the water inlet chamber rises and opening the water inlet when the water level of the water inlet chamber drops. According to the rainwater treatment device, initial rainwater and rainwater in the middle and later periods can be separated, the initial rainwater can be directly purified and then discharged, and the surface runoff control rate and the non-point source pollution reduction rate are increased.
本发明属于水资源回收、海绵城市建设、雨水管控领域，公开了一种雨水处理装置，包括筒体、过滤筒和阀板机构，筒体内设有竖直设置的隔板，隔板将筒体分隔为溢流室和进水室，溢流室设置有出水口，进水室设置有进水口和反流口，进水口位于所述反流口的下方；过滤筒设置在溢流室内，过滤筒的入水口与进水室连通，过滤筒的排水口与出水口连通，过滤筒的外壁与筒体的内壁之间具有间距，过滤筒用于对雨水进行过滤；阀板机构设置在进水室内，用于在进水室水位上升时关闭入水口，在进水室的水位下降时打开入水口。本发明不仅可对初期雨水与中后期雨水进行分离，而且可直接对初期雨水进行净化后再外排，提高地表径流控制率与面源污染削减率。
