Rainwater treatment device for sponge city

Abstract

The invention relates to the technical field of rainwater treatment equipment for a sponge city, and discloses a rainwater treatment device for a sponge city. The rainwater treatment device comprisesa box body, wherein the bottom of the inner wall of the box body is fixedly provided with a water storage tank; the top of the box body is fixedly connected with an L-shaped pipe in a sleeving way; the top of the L-shaped pipe is fixedly connected with a first water inlet; the right end of the L-shaped pipe is fixedly connected with a U-shaped pipe in a sleeving way through a fastening sleeve; thetop of the water storage tank is fixedly provided with a sedimentation tank. The rainwater treatment device for the sponge city has the advantages that through the matching of the U-shaped pipe, a first valve and the sedimentation tank, hybrid substances in rainwater entering from the first water inlet pass through a pipe opening communicated with the sedimentation tank; solid particles fall intothe sedimentation tank, so that solid particles and weighed impurities are filtered out; the flowing rainwater is primarily filtered and cleaned; the pipeline blockage due to full impurity piling ofthe sedimentation tank is avoided, so that the filtered impurities are timely treated; the blockage cannot easily occur.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment equipment for sponge cities, in particular to a rainwater treatment device for sponge cities. Background technique [0002] Sponge city is a new generation of urban stormwater management concept. It refers to the city's good "elasticity" in adapting to environmental changes and responding to natural disasters caused by rainwater. It can also be called "water elastic city". The international general term is "low-impact development stormwater system construction". When it rains, it absorbs, stores, infiltrates, and purifies water, and "releases" the stored water for use when needed. Substantial application of "sponge city" materials, showing excellent water seepage, compression resistance, wear resistance, non-slip, environmental protection, beautiful and colorful, comfortable and easy to maintain, sound absorption and noise reduction, etc., has become a "breathing" urban landscape pave...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a rainwater treatment device for sponge cities, which has the advantages of being convenient for timely processing of filtered impurities, not easy to be blocked, and convenient for flood discharge and storage, and solves the problems of existing rainwater treatment devices During sewage treatment, pollutants and impurities cannot be effectively cleaned up in time, and the existing rainwater treatment device cannot timely dump the filtered and precipitated impurities, which is easy to cause blockage, which is not conducive to the long-term use of the rainwater treatment device. And it is easy to cause the quality of rainwater to be treated later to decline, and it is not conducive to the storage of rainwater in the later stage
