Problems solved by technology

However, when the precipitation is large, a large amount of rainwater washes the ground, and the dust and sand on the ground are brought into the underground waterway together. The rainwater is mixed with a large amount of dust, sand, etc., which causes a huge burden on the purification device for rainwater purification.

Embodiment Construction

[0034] The following is attached Figure 1-4 The application is described in further detail.

[0035] refer to figure 1 with figure 2 The sponge city rainwater recycling system includes a drainage ditch 1 and an underground waterway 2 , the drainage ditch 1 is arranged above the underground waterway 2 , and a drainage hole 5 communicating with the underground waterway 2 is opened on the drainage ditch 1 . In rainy weather, after the rainwater flows into the drainage ditch 1, it is discharged into the underground waterway 2 from the drainage hole 5, and then flows to the rainwater purification device for purification.

[0036] refer to figure 1 A plurality of retaining ribs 6 are integrally formed on the inner bottom surface of the drain ditch 1 , the length direction of the retaining ribs 6 is parallel to the width direction of the drain ditch 1 , and the plurality of retaining ribs 6 are arranged at intervals along the length direction of the drain ditch 1 . The section ...

Abstract

The invention relates to the field of water supply and drainage construction, in particular to a sponge city rainwater recycling system which comprises a drainage ditch and an underground water channel, the drainage ditch is arranged above the underground water channel, a drainage hole communicated with the underground water channel is formed in the inner bottom face of the drainage ditch, a supporting column is arranged in the underground water channel, and a rotating assembly is arranged on the supporting column. A purification assembly used for receiving rainwater and filtering the rainwater is arranged on the rotating assembly and extends to the position below the drainage hole. The rainwater purification device has the effects of reducing gravel and the like mixed in rainwater and relieving the purification pressure of the rainwater purification device.

Description

technical field [0001] This application relates to the field of water supply and drainage construction, in particular to a sponge city rainwater recycling system. Background technique [0002] Sponge city refers to the fact that the city, like a sponge, has good resilience in adapting to environmental changes and dealing with natural disasters caused by rain. When it rains, it absorbs, stores, infiltrates, and purifies water, and releases and utilizes the stored water when needed, so as to realize the free migration of rainwater in the city. [0003] In rainy weather, rainwater flows along the underground waterway to the rainwater purification device, and is stored after being purified by the rainwater purification device. However, when the precipitation is large, a large amount of rainwater washes the ground, and the dust and sand on the ground are brought into the underground waterway together. The rainwater is mixed with a large amount of dust, sand, etc., which causes a...
