Sponge city rainwater collection and utilization system
The invention relates to a sponge city rainwater collection and utilization system. A flow discarding and sewage intercepting device is connected with a rainwater well, a reservoir is connected with the flow discarding and sewage intercepting device, and the flow discarding and sewage intercepting device is connected with a sewage discharging pipeline. An overhaul well and a water outlet well are arranged in the reservoir, and the water outlet well, a rainwater purification device, a clean water tank and a rainwater recycling device are sequentially connected. The reservoir comprises a rainwater storage module, a backwashing device, a pollution discharge device and a rainwater lifting pump, the rainwater storage module is arranged in a concrete foundation pit and is wrapped by an impermeable film, and the overhaul well and the water outlet well are arranged in the rainwater storage module. A backwashing device and a blowdown device are arranged at the bottom of the rainwater storage module. The rainwater lifting pump is arranged in the water outlet well and communicates with the rainwater purification device. Geotextile, the medium sand layer and the original soil layer are sequentially covered above the reservoir. According to the sponge city rainwater collection and utilization system, rainfall can be effectively collected and utilized, the problem of urban waterlogging is solved, and utilization of water resources is promoted.
本发明涉及一种海绵城市雨水收集利用系统，包括：弃流截污装置和雨水井连接，蓄水池与弃流截污装置连接，且弃流截污装置与排污管道连接。检修井、出水井均设置在蓄水池中，出水井、雨水净化装置、清水池、雨水回用装置依次连接。蓄水池包括雨水蓄水模块、反冲洗装置、排污装置、雨水提升泵，雨水蓄水模块设置在混凝土基坑中，雨水蓄水模块被防渗膜包裹，检修井、出水井设置在雨水蓄水模块中。反冲洗装置和排污装置均设置在雨水蓄水模块的底部。雨水提升泵设置在出水井中，且雨水提升泵与雨水净化装置连通。蓄水池的上方依次覆盖土工布、中砂层和原土层。本发明的这种系统能够有效收集和利用降雨，既缓解了城市的内涝问题，又促进了水资源的利用。
