Rain and sewage filtering device for sponge city rainfall flood management and capable of improving water utilization rate

Abstract

The invention discloses a rain and sewage filtering device for sponge city rainfall flood management and capable of improving the water utilization rate. The rain and sewage filtering device comprisesa shell body, an impurity concentration barrel, a top cover and a filtering screen, wherein a connecting column is arranged at one side above the outer part of the shell body; a sewage outlet is arranged on the front surface of a rainwater filter; the lower side of the impurity concentration barrel is connected with a transition tank through an inserting block; an activated carbon filtering frameis arranged above the transition tank and an inserting groove is reserved in the upper surface of the transition tank; the top cover is mounted above the shell body through a positioning column; a connecting groove is reserved at one side of the shell body; a water passing hole is reserved in the surface of a transverse rod on the top cover; the filtering screen is arranged at the bottom of the impurity concentration barrel. The rain and sewage filtering device for the sponge city rainfall flood management and capable of improving the water utilization rate, disclosed by the invention, can beused for filtering rainwater and collecting and storing impurities doped in the rainwater, so that the rainwater can be more rapidly and comprehensively filtered, and the recycling rate of the rainwater is effectively improved.

Description

technical field [0001] The invention relates to the technical field of stormwater management in sponge cities, in particular to a rainwater filter device for stormwater management in sponge cities that improves water utilization. Background technique [0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". In sponge city In rainwater management, it is often necessary to set up corresponding rainwater filtration devices to recycle rainwater resources. However, most rainwater filtration devices for rainwater management in sponge cities are inconvenient to treat rainwater well when collecting rainwater. If the mixed sundries are recycled and concentrated, it is easy to cause the rainwater mixed with sundries to block the pipeline, which reduces the circulation efficiency ...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a kind of rainwater filtering device for rainwater management of sponge city which improves water utilization rate, to solve the above-mentioned background technology and present most of rainwater filtering devices for rainwater management of sponge city are inconvenient when collecting rainwater It is very good to recover and concentrate the mixed sundries in the rainwater, and it is easy to cause the rainwater mixed with sundries to block the pipeline, which reduces the circulation efficiency of rainwater, and thus cannot improve the utilization rate of rainwater very well.
