Rainwater sewage interception and purification device based on sponge city
The invention provides a rainwater sewage interception and purification device based on a sponge city, and relates to the technical field of rainwater sewage interception and purification. The devicesolves the problems that a rainwater sewage interception device in the prior art mostly adopts a sewage interception hanging basket to intercept sundries such as leaves and branches contained in rainwater, but once there are too many intercepted sundries such as the leaves and the branches, meshes of the sewage interception hanging basket can be blocked, the permeation efficiency of the rainwateris affected, and the rainwater overflow phenomenon occurs at a rainwater sewage interception part due to the low permeation efficiency of the rainwater under the rainy day condition. The rainwater sewage interception and purification device based on the sponge city comprises a pre-buried rainwater conveying mechanism, and the pre-buried rainwater conveying mechanism is pre-buried in a rainwater pipe duct part. Even if a small amount of sundries such as the leaves and the branches fall into a secondary filtering interception mechanism along a gap between the outer circumferential surface of a circular plate B and the inner circumferential surface of a cylinder, the small amount of sundries such as the leaves and the branches can also be intercepted by a U-shaped geotextile filter bag, and the sundries such as the leaves and the branches are prevented from flowing into a rainwater inlet branch pipe.
本发明提供一种基于海绵城市的雨水截污净化装置，涉及雨水截污净化技术领域，解决了现有雨水截污装置多采用截污挂篮对雨水中所包含的树叶、树枝等杂物进行拦截，但拦截的树叶、树枝等杂物一旦过多，其将会堵塞住截污挂篮的网孔，影响雨水的渗透效率，导致雨天条件下，因雨水的渗透效率低，导致雨水截污部位发生雨水溢出现象的问题。一种基于海绵城市的雨水截污净化装置，包括预埋式雨水输送机构，所述预埋式雨水输送机构预埋安装在雨水管渠部位。即便有少量树叶、树枝等杂物沿圆板B外周面与筒体内周面之间的空隙掉落至二级过滤拦截机构内时，该少量树叶、树枝等杂物也将经由U型土工布过滤袋所拦截，避免树叶、树枝等杂物流入雨水口支管内。
