Embodiment Construction

[0037] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0038] refer to figure 1, is a sponge city rainwater treatment system disclosed in the present invention, including a permeable layer 1, an aquifer 2, a water purification layer 3 and a water collection layer 4 arranged from top to bottom. The infiltration layer 1 is for the rainwater on the surface and the road to infiltrate naturally downwards, such as planting soil and the like. Rainwater is stored in the aquifer 2, and the purpose of collecting the rainwater infiltrated from the ground surface and the road surface. The water purification layer 3 plays the role of water purification, and can be filled with stone or bamboo charcoal. The rainwater reaches the water collection layer 4 after passing through the water purification layer 3 .

[0039] Such as figure 1 As shown, the water collecting layer 4 is provided with a primary clean water chamber 41 and...

Abstract

The invention discloses a sponge city rainwater treatment system, and belongs to the technical field of sponge cities. The technical scheme key points of the system include a permeable layer, an aquifer, a water purification layer and a water catchment layer, wherein the water catchment layer is connected with a water supply device, and the water catchment layer is internally provided with a first-stage clear water cavity and a second-stage clear water cavity; a deepening filter assembly is arranged between the first-stage clear water cavity and the second-stage clear water cavity; and the water supply device includes a first water supply assembly and a second water supply assembly, wherein the first water supply assembly is connected with the first-stage clear water cavity, and the secondwater supply assembly is connected with the second-stage clear water cavity. According to the sponge city rainwater treatment system, an effect of improving the utilization rate of rainwater is achieved.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a rainwater treatment system for sponge cities. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". To build a sponge city, coordinate the use of natural ecological functions and artificial intervention functions, effectively control rainwater runoff, and realize the urban development mode of natural accumulation, natural infiltration, and natural purification, which is conducive to restoring urban water ecology, conserving water resources, and enhancing urban waterlogging prevention capabilities. Expand effective investment in public goods, improve the quality of new urbanization, and promote the harmonious development of man and nature. [0003] The existing Chinese patent whose public...
