River flow-separating purification beautification treatment system and method

Abstract

The invention discloses a river flow-separating purification beautification treatment system and method. A damming system comprises a hydraulic turnover plate gate which is arranged at the bottom of a riverbed, and a water retaining breast wall which is used in cooperation with the hydraulic turnover plate gate, wherein a flow drainage channel is formed between the hydraulic turnover plate gate and the water retaining breast wall, and the hydraulic turnover plate gate automatically adjusts the degree of opening of the flow drainage channel along with changes of the river discharge to have control over the discharged flow, and keeps the water level of the damming system stable. A flow separating system is arranged on the lower section of the damming system, a reinforced concrete cover plate is arranged on the tops of quay walls of a river channel, the cover plate covers the whole river channel, river water on the upper layer of the damming system flows through the cover plate, river water on the lower layer of the damming system is separated to flow through the river channel formed below the cover plate, sewage tanks are built on the lower portion, close to the quay walls on the two banks, of the river channel arranged below the cover plate, and urban sewage, flowing into the river channel, on the two banks can be guided to the downstream portion, and can flow into a sewage treatment system. According to the river flow-separating purification beautification treatment system and method, land can be saved, the visual field can be beautified, construction cost can be reduced, and management is convenient.

Description

technical field [0001] The invention relates to the field of river purification and beautification, in particular to a river diversion purification and beautification management system and method that can save land, beautify the field of vision, reduce construction costs and facilitate management. Background technique [0002] With the rapid increase of population and the improvement of people's living standards, the amount of domestic sewage has increased significantly. [0003] At present, most of the urban sections of rivers in mountainous areas are channelized due to the narrow water flow caused by the construction of bank walls, which destroys the natural form of the river. Smelly ditch. In order to beautify the urban sections of rivers, it is often necessary to build sluice gates or rubber dams to raise the water surface to form waterscapes (hereinafter referred to as "gate and dam method"). As a mountainous river, the longitudinal slope is very large, about 0.1-1.0%...

AI Technical Summary

Problems solved by technology

Not only the cost is high, but also can not form a good landscape effect

At the same time, because the depth of backwater ranges from shallow to deep, people in the shallow section cannot get close to the water (the height difference between the bank wall and the water surface is too large), and it is not safe to be close to the water in the deep section, and the relationship between people and water is not intimate and harmonious.

[0004] Among the existing methods for purifying and beautifying rivers, the gate and dam method requires the construction of a sewer pipe network in addition to submerging a large area of ​​land to form a landscaping water surface. There is also the problem that the landscape effect is not good, and the relationship between the landscape water body and people is not intimate and harmonious.
