Sponge city rainwater treatment system

Abstract

The invention relates to a sponge city rainwater treatment system, and relates to the technical field of sponge cities. The sponge city rainwater treatment system comprises a base soil layer; a planting belt is arranged on the base soil layer; a water storage tank is arranged in the planting belt; a water storage module communicated with the water storage tank is arranged in the base soil layer; the water storage module comprises a rainwater regulating tank, a PP module group collecting tank and a filtering front pool; a residential area is arranged on the base soil layer; the residential areais connected with the filtering front pool; the base soil layer is provided with a water-permeable pavement mould frame for rainwater to penetrate into the base soil layer; the water-permeable pavement mould frame comprises a brick groove, a water-permeable groove and a cushion layer arranged below the water-permeable groove. By arranging a rainwater regulating tank, a PP module group collectingtank, and a filtering front pool, when in extreme rainfall conditions, excess rainwater can be collected so that the sponge city can still drain normally in the face of extreme rainfall.

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 means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city", an international general term For "Low Impact Development Stormwater System Components". Its main function is to absorb water, store water, seep water, purify water when it rains, and "release" the stored water and use it when needed. [0003] 1. Water seepage in sponge cities: With the advancement of urbanization, the natural ecology of cities is also facing severe imbalances. Urban roads are hardened and paved with impermeable materials everywhere, changing the original natural ecological ontology and hydrological characteristics. Therefor...

Problems solved by technology

However, in some coastal cities, especially in the case of extreme rainfall, sponge cities are still unable to effectively deal with rainwater and fall into the embarrassment of "waterlogged into the sea"
