Water circulation structure based on sponge city

Abstract

The invention discloses a water circulation structure based on a sponge city, and solves the problem of reduction of water quality, which is caused by a case that water stored by an existing water storage structure of the sponge city is in an non-circulated state for a long term. The technical scheme of the invention has the key points that the water circulation structure comprises a reservoir used as a sponge city water storage structure, and further comprises a pump station, a fountain-type oxygen-increasing pool and a waterfall-type oxygen-increasing pool; the pump station is used for pumping water in the reservoir to the fountain-type oxygen-increasing pool and forming a fountain landscape; the waterfall-type oxygen-increasing pool is arranged at one side of the fountain-type oxygen-increasing pool, and the waterfall-type oxygen-increasing pool comprises a waterfall forming wall arranged close to the fountain-type oxygen-increasing pool; when the fountain-type oxygen-increasing pool overflows, water flows into the waterfall-type oxygen-increasing pool through the waterfall forming wall; the horizontal position of the waterfall-type oxygen-increasing pool is lower than that of the fountain-type oxygen-increasing pool; the waterfall-type oxygen-increasing pool is communicated with the reservoir. The water circulation structure achieves the advantage of improving water quality, and creates the waterscape in the flowing process of water so as to beautify the environment.

Description

technical field [0001] The invention relates to the technical field of water resources treatment and utilization, more specifically, it relates to a water circulation structure based on a sponge city. 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". [0003] For example, the Chinese utility model patent with the authorized announcement number CN206512819U announced a sponge city road drainage and water storage structure. Use the overflow pipe to collect the overflowing water in the reservoir. When the water in the reservoir reaches the aqueduct, the water in the reservoir can be introduced into the planting soil layer, and the plants in the planting belt can be self-treated Irrigation, and when there is excess rainwater in the planting bel...

[0004] The above-mentioned prior art collects and stores rainwater in seepage wells and cisterns. Usually, these water resources will be stored in the above-mentioned seepage wells and cisterns for a long time before being reused, becoming "dead water", so that the self-purification of this part of water The capacity is weakened, resulting in a decline in water quality and even rancidity
