Buried municipal square rainwater collection system

Abstract

The invention relates to the technical field of municipal rainwater treatment, and aims to provide a buried municipal square rainwater collection system which comprises a drainage mechanism, a confluence mechanism and a rainwater treatment mechanism. The drainage mechanism comprises a linear drainage ditch and a purified water collecting pipeline which communicate with each other through a connecting pipeline; a filtering device and a leakage-proof device are arranged in the connecting pipeline; the confluence mechanism comprises a sewage transfer box communicating with the linear drainage ditch and a purified water transfer box communicating with the purified water collecting pipeline; and the sewage transfer box is connected with the rainwater treatment mechanism. When rainwater flowinginto the linear drainage ditch passes through the connecting pipeline, part of the rainwater can be treated by the filtering device, enters the purified water collecting pipeline downwards and is finally stored in the purified water transfer box, so that the sewage storage capacity is reduced, the purified water storage capacity is increased, meanwhile, the rainwater treatment efficiency is improved, and therefore the rainwater collection and utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of municipal rainwater treatment, in particular to an underground rainwater collection system for municipal squares. Background technique [0002] With the development of society and the rapid expansion of population, the shortage of water resources is becoming more and more serious. While protecting water resources, we must also think about how to make better use of water resources. [0003] At present, the Chinese patent document with the authorized announcement number CN205776487U in the prior art discloses a rainwater collection system for underground municipal squares, including a water collection tank and a water treatment tank. It is connected to the water collection tank through the water collection pipe, and the rainwater collected on the square floor flows into the water collection tank through the water collection pipe, and the ozone generator is used to generate ozone in the water collection tank...

AI Technical Summary

Problems solved by technology

[0004] However, many squares have a large area, and it is difficult to collect rainwater from various places through the lower square floor. Most squares use drainage ditch systems for confluence and drainage to avoid water accumulation in some areas; The amount of rainwater collected by the drainage ditch system is large and rapid, which will cause the speed of rainwater purification treatment to fail to keep up with the speed of water intake in the collection tank, and the overflowing rainwater can only be discharged into the sewer, resulting in a low utilization rate of rainwater collection
