Abstract

The invention provides a rainwater collection and treatment system for a sponge city. The system comprises a site rainwater pipe network, the site rainwater pipe network comprises a plurality of sub-catchment areas obtained by dividing a site according to areas in advance, according to each of the sub-catchment areas, by using a drain pipeline, a part of rainwater splits, and is collected and concentrated to a rainwater main pipeline, the other part splits to a municipal drainage pipeline, the rainwater main pipeline delivers the rainwater to a rainwater collecting pool through a rainwater intercepting and basket hanging device, a rainwater abandonment filtering device and a rainwater filtering device buried under the ground surface, the rainwater collecting pool is provided with an inspection well and a reusing well, recovered water in the rainwater collecting pool is lifted to the ground through a lifting pump in the reusing well, is further purified by a purifying integrated machine, and then is used for road washing or green irrigation. The system is managed according to regions, abides by the principle of ecological priority, promotes the utilization of rainwater resources andecological environment protection, reduces the discharging amount of regional rainwater runoff, and achieves ecological effects.

Description

technical field [0001] The invention belongs to the field of urban planning and design and urban water conservancy facilities, and in particular relates to a rainwater collection and treatment system for sponge cities. Background technique [0002] With the continuous development of cities, many "over-urbanization" phenomena have emerged, resulting in a series of contradictions and problems called "urban diseases": traffic congestion, environmental pollution, water shortage, urban waterlogging, urban heat island effect, etc. Wait. [0003] Sponge city refers to a city that can be like a sponge and has good flexibility in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and releases and utilizes the stored water when needed. To solve urban problems, we must conform to nature. When upgrading the urban drainage system, it is necessary to give priority to retaining limited rainwater, give...
