Area partitioned rainwater flow distribution, storage regulation and processing system based on combined-system pipe network

Abstract

The invention discloses an area partitioned rainwater flow distribution, storage regulation and processing system based on a combined-system pipe network. According to the system, an urban water processing system is divided into a plurality of independent water body processing districts, wherein the area of each water body processing district is 0.2-4 square kilometers; independent small-scale rainwater processing facilities are arranged in the water body processing districts, and each rainwater processing facility only needs to process rainwater flowing out of a rainwater branch pipe corresponding to the corresponding water body processing district and sewage flowing out of a sewage branch pipe corresponding to the corresponding water body processing district; the area of the water body processing districts is small, and therefore the time difference between the time when rainwater at the point far away from the rainwater processing facility is converged to the rainwater processing facility and the time when rainwater at the point close to the rainwater processing facility is converged to the rainwater processing facility in each district is small, the problem that primary rain contains a large amount of later-period rainwater because of the convergence time differences of the far points and the near points of the pipe network is solved, the mixing degree of primary rainwater and later-period rainwater is greatly lowered, the processing effect of rainwater is remarkably improved, and the aim of effectively, unceasingly and efficiently conducting filtration and purification in combined-system pipelines is achieved.

Description

technical field [0001] The invention relates to the technical field of rainwater treatment, in particular to a rainwater diversion, regulation and storage and treatment system for regional slices based on a combined pipe network. Background technique [0002] In the current society, urbanization is developing more and more rapidly, the area of ​​the city is getting larger and larger, the structure of the urban rainwater pipe network is becoming more and more complex, and the pressure on the urban rainwater treatment system is increasing. However, with the continuous expansion of the city, the existing rainwater pipe network structure has great defects. The urban pipe network generally divides the entire urban structure into several areas, and a separate water treatment system is set in each area. However, the existing urban The water body treatment system is unreasonable for the regulation of initial rainwater and later rainwater, and cannot be completely separated. [0003...

AI Technical Summary

Problems solved by technology

As a result, the water body collected by the abandoned flow well is essentially a combination of relatively clean initial water body and a large amount of mixed water body, which leads to unsatisfactory water treatment effect and cannot effectively, continuously and efficiently filter and purify urban combined pipelines

[0005] Although the existing water body treatment system of the combined pipe network in the urban area is also equipped with multiple abandonment wells, the time difference between the confluence of the distant water body and the incoming water body is not considered when setting the abandonment wells, which leads to unsatisfactory water treatment effects. , unable to filter and purify the urban combined pipeline effectively, continuously and efficiently
