Aeration system for river restoration

Abstract

The invention discloses an aeration system for river restoration in the technical field of river restoration, and aims to solve the technical problem in the prior art that an operating cycle and an aeration volume of micro-porous aeration are determined according to experience, deviation of aeration accuracy is large, the resource consumption amount is large, and the influence of water flow on oxygen diffusion and transfer is not fully considered in an aeration process. The aeration system comprises an aeration control module, wherein the aeration control module is connected with an aeration control center, a fan sends air to the aeration control module through a ventilation pipeline, the aeration control module sends the air to multiple aerators through ventilation branch pipelines, the aeration control module adjusts an aeration volume and an aeration time of each aerator, an aerator control module is arranged on each aerator, and the aeration control center controls the aerators through the aerator control modules. The system has small dependence on engineer experience, small energy consumption amount, and enhanced aeration effects, can adjust an aeration process in real time inaccordance with specific hydrological conditions, and realizes real-time monitoring of the aeration process.

Description

technical field [0001] The invention belongs to the technical field of river restoration, and in particular relates to an aeration system for river restoration. Background technique [0002] Aeration is a common in-situ restoration technology for rivers. Its principle is to increase the dissolved oxygen concentration in river water, promote the metabolism of microbial aerobic flora in rivers, enhance the self-purification ability of rivers, and achieve the effect of decomposing pollutants. The existing aeration methods are mainly divided into two categories, mechanical aeration and blast aeration. Mechanical aeration has a large disturbance to the water body, and when used in rivers, it will cause resuspension of the river sediment and the release of pollutants in the sediment to the water body, which will affect the water quality of the downstream river, so it is often used in the aeration tank of the sewage treatment plant. Not for in situ aeration of rivers. Blast aerat...
