Urban rainwater collecting, purifying and storage-regulating ecological utilization system

Abstract

The invention discloses an urban rainwater collecting, purifying and storage-regulating ecological utilization system. The urban rainwater collecting, purifying and storage-regulating ecological utilization system comprises a rainwater collecting part, a plant filter band, a filter part, a rainwater collecting pond and a rain water storage pond. The rainwater collecting part is connected to the filter part, the plant filter band is located on the upper part of the filter part, the filter part communicates to the rainwater collecting pond, the rainwater collecting pond is connected to the rainwater storage pond, the filter part comprises a grid bracket, ores and a filter layer, the ores are divided into multiple layers, the ores are paved in the grid bracket, and the ores are one or more ores, and the filter layer is located on the side face of the grid bracket and communicates to the rainwater collecting pond. In this way, the urban rainwater collecting, purifying and storage-regulating ecological utilization system has the benefits of storing rainwater, supplementing irrigation water for urban afforestation effectively, and promoting ecological balance of the urban environment.

Description

technical field [0001] The invention relates to the technical field of rainwater collection and purification, in particular to an urban rainwater collection, purification, adjustment and storage ecological utilization system. Background technique [0002] Rainwater harvesting refers to the collection and use of rainfall runoff collected on hardened surfaces such as building roofs, roads, squares, etc., through collection, water delivery, water purification, storage and other channels, and rainwater harvesting provides rainwater for greening, landscape water bodies, washing and groundwater sources Recharge, in order to achieve the purpose of comprehensive utilization of rainwater resources and water conservation. Rainwater harvesting has a wide range of meanings, such as slowing down urban rainwater flooding and groundwater level drop, controlling rainwater runoff pollution, and improving urban ecological environment. Rainwater collection uses buildings, roads, lakes, etc. t...

AI Technical Summary

Problems solved by technology

[0003] Traditional rainwater harvesting methods have poor or impermeable water permeability, do not use infiltration and accumulation of rainwater, and cannot effectively supplement groundwater, which affects ecological effects and ecological value

Some use chemical treatment to treat rainwater, which is expensive, difficult to maintain, and the water quality cannot meet the growth requirements of aquatic plants and fish in rivers and lakes
