Novel intelligent grid stormwater and flood management system

Abstract

The invention discloses a novel intelligent grid stormwater and flood management system. The system comprises a plurality of subsystems. Each subsystem comprises a plurality of rainwater treatment modules. Each rainwater treatment module is composed of a collection device, a rainwater discarding device, a filtering and purifying device and a storage and leakage device which are arranged on the ground or on the lower portion of the kerb, wherein the rainwater discarding device and the filtering and purifying device are arranged on the storage device, the collection device is connected with a water inlet of the rainwater discarding device through a pipeline, the rainwater discarding device is communicated with the filtering and purifying device through a liquid guide opening, and the filtering and purifying device is communicated with the inside of the storage and leakage device through a rainwater collection pipe. According to planned initial rainwater discarding values of cities, the functions of rainwater collection, precise discarding, filtering, storage and leakage can be precisely achieved under any rainfall condition, flood drainage safety can be effectively guaranteed, the structure is reliable, and maintenance is convenient. Meanwhile, rainwater treatment conditions in an implementation area can be monitored as a whole, big data management of sponge city planning is achieved, and the ecological environment in the area is improved.

Description

technical field [0001] The invention relates to a rainwater treatment system, in particular to a rainwater collection, discarding, filtering, storing, and seepage system used in the construction of a sponge city. Background technique [0002] The rainwater management system in the existing cities mainly adopts a tree structure. The rainwater inlet is equivalent to the terminal leaves of the tree, and the rainwater branch pipes installed underground are equivalent to small branches. The above-mentioned smaller rainwater branch pipes funnel rainwater into larger branch pipes , and the rainwater branch pipes flow into the rainwater main road. The disadvantages of tree-shaped stormwater management are: 1. Since the collected rainwater comes from different regions and at different time points, the composition content of the rainwater is different, which is not conducive to the initial rainwater abandonment and the purification treatment of later rainwater; 2. When the system part...

AI Technical Summary

Problems solved by technology

The disadvantages of tree-shaped stormwater management are: 1. Since the collected rainwater comes from different regions and at different time points, the composition content of the rainwater is different, which is not conducive to the initial rainwater abandonment and the purification treatment of later rainwater; 2. When the system partially drains When the flood is not smooth, the superposition of upstream rainwater and flood exceeds the processing range of the branch, resulting in the decline or collapse of the entire system processing function
