Watercourse aeration apparatus installation method

Abstract

The invention provides a watercourse aeration apparatus installation method, which comprises the following steps: carrying out aeration by the use of an aerator pipe, laying the aerator pipe at a setposition in a watercourse, and fixing the aerator pipe temporarily; arranging a guiding pile in the watercourse, and removably installing the aerator pipe on the guiding pile; adding counterweight forthe aerator pipe; setting air supply pressure of the aerator pipe to be greater than weight of the counterweight of the aerator pipe, supplying gas for the aerator pipe, and letting the aerator pipestart to operate. The watercourse aeration apparatus installation method is suitable for polluted river water body restoration, has low installation and construction difficulty, and has high safe 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
