Sponge city rainwater collecting and treating system and rainwater collecting and treating method thereof

Abstract

The invention discloses a sponge city rainwater collecting and treating system and a rainwater collecting and treating method thereof. The sponge city rainwater collecting and treating system comprises a drainage system, a rainwater permeating unit, a rainwater storage unit, a rainwater treating unit and a rainwater recycling unit; the drainage system comprises a rainwater collecting groove, a drainage pipe, a drainage pool and a water feeding pipe; the rainwater collecting groove is connected with the drainage pool through the drainage pipe, and the drainage pool is communicated with the rainwater permeating unit through the water feeding pipe; the rainwater permeating unit is arranged on a sponge city greenbelt; the rainwater permeating unit feeds collected rainwater to an underground rainwater storage unit; the rainwater treating unit filters the rainwater many times, and the sterilized rainwater is fed to a place where water is needed through the rainwater recycling unit. By meansof the sponge city rainwater collecting and treating system, the rainwater is reutilized to irrigating, washing toilets, flushing vehicles and supplementing scenery water, saves tap water, reduces thecost of water treatment and effectively solves the problem of water resource shortage.

Description

technical field [0001] The invention belongs to the technical field of urban water treatment, and in particular relates to a sponge city rainwater collection and treatment system and a rainwater collection and treatment method thereof. Background technique [0002] Sponge city, as the name suggests, is a city like a sponge. During the rainy season, the rainwater in the city can be collected, stored and purified. When water resources are needed, the stored water resources can be released for use. [0003] 50% of most cities in our country are short of water or even seriously short of water. Utilizing water resources, especially rainwater resources, is an important way to effectively solve the shortage of urban water resources. To reuse rainwater resources, it is first necessary to collect and store rainwater resources. Rainwater storage projects can effectively reuse rainwater and solve the problem of water shortage. [0004] However, the current rainwater storage system mos...

Problems solved by technology

However, there is currently no reasonable urban planning for a complete system for utilizing storm water

When there is a lot of rainfall, pumps and other methods are used to drain water or this traditional method leads to timely drainage and wastes water resources
