Rainwater percolation, accumulation and purification system

Abstract

The invention provides a rainwater percolation, accumulation and purification system, which comprises a natural percolation and collection system and a manual percolation and collection system, wherein the natural percolation and collection system sequentially comprises a pervious concrete layer, a laying layer, a percolation layer and a pressure bearing layer; the laying layer is formed by splicing a plurality of laying mechanisms; the manual percolation and collection system comprises a percolation well and an impounding reservoir; on the premise of ensuring the urban waterlogging security,the collection, the percolation, the purification and the utilization of the rainwater in the urban range are realized to the greatest degree; the urban waterlogging pressure can be effectively relieved and reduced; the utilization of rainwater resources is promoted; and the requirement of sponge city building is met.

Description

technical field [0001] The invention belongs to a purification system, in particular to a rainwater percolation, storage and purification system. 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. "Come out and take advantage of it. Under the premise of ensuring the safety of urban drainage and waterlogging prevention, sponge cities can maximize the accumulation, infiltration and purification of rainwater in urban areas, promote the reuse of rainwater resources and ecological environment protection, and realize the high standards proposed by the state for urban rainwater management and new requirements. The rainwater purification system refers to a system that collects rainwater according to demand, and purifies the collected rainwater to meet the use standards. The collected rainwater is roughly divided into two categories, roof rainwater ...

AI Technical Summary

Problems solved by technology

The collected rainwater is roughly divided into two categories, roof rainwater and road surface rainwater. Considering the serious air pollution in our country, the collected rainwater has many impurities and complex sources of pollutants. The reused water obtained by the existing rainwater purification device There is still the problem of poor water quality, which cannot meet the needs of urban systems, and the comprehensive utilization rate of collected rainwater is low, which does not meet the concept and requirements of sponge city construction and ecological environment protection.
