A method for installing a river aeration device

Abstract

The invention provides a method for installing a river channel aeration device, which includes the following steps: using an aeration tube to aerate, laying the aeration tube at a set position in the river channel, and temporarily fixing the aeration tube; setting guide piles in the channel, placing the The aeration tube is movable and installed on the guide pile; counterweight the aeration tube; set the air supply pressure of the aeration tube to be greater than the counterweight weight of the aeration tube, supply air to the aeration tube, and the aeration tube starts Work. The invention has the advantages of being applicable to the restoration of river water pollution, low difficulty in installation and construction, and high safety and reliability.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an installation method of a river aeration device. Background technique [0002] Urban black and odorous water is a serious water environment problem, which can easily lead to problems such as nutrient enrichment in river sediment, black and smelly water, and serious siltation in the middle of the river. Moreover, the river's water flow capacity is poor, which affects the river's sewage discharge and flood control. Drainage and irrigation functions not only damage the urban living environment, but also seriously affect the image of the city. [0003] In order to improve the pollution of water bodies, the existing method is to use aeration technology. The principle is to transport air into the aeration device, disperse and escape in the form of bubbles, and dissolve oxygen into the water at the gas-liquid interface to increase the dissolved oxygen in the water. the goal of. The m...

AI Technical Summary

Problems solved by technology

However, the existing aeration technology is mainly used in the aeration tank of the sewage treatment plant. Due to the complex geographical location and wide laying range of the river water pollution restoration, the application of the aeration technology in the river water pollution restoration project is limited. Cofferdam construction and high operational requirements lead to problems such as complex installation, high construction costs, and low safety and reliability of aeration pipe construction; at the same time, the application of aeration pipes in river courses will hinder the normal passage of ships and affect the navigation capacity of rivers
