Water circulating system for sponge city construction

Abstract

The invention discloses a water circulating system for sponge city construction. The water circulating system for sponge city construction is characterized by comprising a rainwater collecting deviceconsisting of a plurality of modularized comprehensive rainwater treating boxes; each modularized comprehensive rainwater treating box comprises a water collector, a filtering mechanism, an enclosuresupport structure and a planting purification structure; the water collector, the filtering mechanism, the enclosure support structure and the planting purification structure are installed from bottomto top; and filtering sponges can be replaced freely.

Description

technical field [0001] The invention relates to the technical field of sponge cities, in particular to a water circulation system for sponge city construction. Background technique [0002] Sponge city refers to a city that can be like a sponge and has good "elasticity" in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water. Use them to gradually improve and restore the city's natural ecological balance. [0003] Sponge city is the concept of a new generation of urban stormwater management. It means that the city can have a certain elasticity like a sponge in the face of environmental changes and natural disasters caused by large amounts of rain. When the city's ground runoff is abundant, the ground These water resources can be reasonably and effectively stored through water absorption, water seepage, and water purification. When urban water resources are scarce, water resources can be rel...

AI Technical Summary

Problems solved by technology

[0007] Since the structure of the rainwater circulation system based on the sponge city disclosed in the above patent is relatively simple, and there are only some filtering structures, the functions that can be realized are relatively simple, so the utilization of rainwater is not complete, and the treatment of rainwater is not thorough.

[0008] In addition, the fully automated rainwater circulation system uses a large number of sensors, such as pressure sensors, liquid level sensors, etc., and also uses a lot of click structures, which makes the overall cost very expensive. The service life of the equipment in the open air environment is limited, so the maintenance and repair expenditure is also very large, which leads to the fact that it cannot be promoted on a large scale

[0009] Due to the sponge city construction of roof greening, it generally adopts several points of integrated design, and uses expensive equipment such as motors and sensors, which makes the cost high and makes it difficult to promote on a large scale.
