An integrated underground water storage and purification system for sponge cities

Abstract

The invention discloses an integrated underground water storage and water purification system for a sponge city, which is mainly composed of a grit chamber, a sunken green space, an underground water storage tank and an equipment room. The rainwater flows into the sunken green land for infiltration pretreatment after sand settling, and then enters the underground storage tank. A rubber soft dam is installed in the underground storage tank to divide the underground storage tank into an upper sewage unit and a lower clean water storage unit. The underground storage tank is connected to the equipment room through pipelines, and the sewage above the underground storage tank is treated by the treatment system in the equipment room and then returned to the water purification storage unit of the storage tank for storage and reuse. This system integrates the functions of rainwater collection, purification, storage and reuse, and realizes the collection, storage, treatment and reuse of rainwater, which plays a role in promoting the construction of sponge cities.

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.
