Abstract

The invention relates to a sponge city rainwater treatment system, which belongs to the field of sponge cities. Including river channels, vegetation layers, water guides, outfalls, water filter layers, water storage layers, rainwater pipes and reservoirs, the vegetation layer is set on the top of the water filter layer, and a certain number of outfalls are set on the vegetation layer , the water storage layer is set at the lowest end, and the water guide is set between the vegetation layer and the water filter layer, wherein the water guide includes a water collection part and a diversion pipe; the water outlet is at the upper end of the water storage layer, the water storage layer and the drainage There is no filter layer in the middle of the mouth; the vegetation layer has a terrain difference from high to low; the rainwater pipe is next to the vegetation layer, close to the river, and the rainwater pipe is below the reservoir, and it is at a certain height of the reservoir A diversion pipe is provided, and the outlet of the diversion pipe is arranged in a river; the present invention can ensure that the road area will not be caused by excessive rainfall, and can realize the accumulation, infiltration and purification of rainwater in urban areas, which is conducive to the full utilization of rainwater resources and ecological environment balance.

Description

technical field [0001] The invention belongs 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. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and when needed, "releases" the stored water and utilizes it. The interception and utilization of rainwater in the initial stage of the sponge city and the infiltration of rainwater in the later stage are the subjects of rainwater treatment that have been widely studied in the construction of sponge cities. [0003] 1) Water seepage in the ecological sponge city [0004] With the advancement...
