Underground water storage and purification integrated system for sponge city

Abstract

The invention discloses an underground water storage and purification integrated system for a sponge city, which is mainly composed of a grit chamber, a sinking green field, an underground reservoir, and an equipment room. Rainwater flows through grits into the sinking green field for permeation pretreatment, and then flows to the underground reservoir. The underground reservoir is internally provided with a soft rubber dam which divides the underground reservoir into an upper sewage unit and a lower purified water storage unit. The underground reservoir and the equipment room are connected by a pipe. Sewage in the upper part inside the underground reservoir is treated by a treatment system in the equipment room and then flows back to the purified water storage unit of the underground reservoir for storage and reuse. The system integrates functions of rainwater collection, purification, storage and reuse. Rainwater collection, diversion and storage and rainwater treatment and reuse are realized. The system helps to push forward the construction of a sponge city.

Description

technical field [0001] The invention relates to the field of rainwater storage and resource utilization, in particular to an integrated underground water storage and purification system for sponge cities. Background technique [0002] In recent years, cities have been frequently hit by heavy rainstorms, causing severe waterlogging. It can be said that "when it rains, it will be flooded, and when it encounters waterlogging, it will collapse." "The city looks at the sea" has become a popular vocabulary. One of the main reasons for urban waterlogging is the low construction standards of urban drainage systems. Many urban constructions have the problem of "emphasizing the surface and ignoring the underground". The system is backward and cannot keep up with the development of the city. [0003] Sponge city refers to a city that can be like a sponge and has good flexibility in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores...

[0003] Sponge city refers to a city that can be like a sponge and has good flexibility in adapting to environmental changes and responding to natural disasters. When it rains, it absorbs, stores, infiltrates, and purifies water, and releases and utilizes the stored water when needed. The current rainwater drainage system only simply discharges rainwater or builds a temporary rainwater storage tank for temporary regulation and storage, which cannot meet the needs of sponge city construction.
