Rainwater filter and filtering method thereof

Abstract

The invention discloses a rainwater filter and a filtering method thereof. The rainwater filter comprises a shell; a rainwater inlet formed in the upper part of the shell; a filter screen assembly arranged in the shell and dividing an inner cavity of the shell into a rainwater filtering chamber and a sewage draining chamber; a rainwater outlet formed in the side, located on the bottom cavity wallof the rainwater filtering cavity, of the shell; and a sewage draining exit arranged at the bottom of the sewage draining chamber. The filter screen assembly is an oval cambered surface filter screenassembly, and the oval cambered surface filter screen assembly comprises two arc section parts, namely a first arc section part and a second arc section part. The first arc section part is a filter screen part with a filtering function and is arranged right opposite to the lower part of the water inlet. The second arc section part is a waterproof part, is positioned at the bottom of the rainwaterfiltering chamber and is used for guiding rainwater into the rainwater outlet.

Description

technical field [0001] The invention discloses a rainwater filter and a filtering method thereof. Background technique [0002] Urban water consumption continues to increase, making urban water issues more and more attention. Especially in southern cities, there is a lot of rainfall and a large amount of rainfall. As rainwater is an available natural resource, proper collection and storage will have a great impact on alleviating the shortage of urban water resources. In order to ease urban traffic, in road construction, viaducts are usually used. When it rains, the rainwater on the viaduct usually flows directly into the urban drainage pipes, causing a waste of water resources. There are generally green belts planted under the viaduct, and the maintenance of the green belt requires a lot of water, and the green belt is located under the viaduct, even if it rains, it cannot be irrigated by rainwater. Financial and water resources, while also affecting traffic. [0003] my...
