Riverway oxygenation device and oxygenation method thereof

Abstract

The invention provides a riverway oxygenation device and an oxygenation method thereof. The riverway oxygenation device comprises a floating platform, oxygen injection mechanisms, a sterilization mechanism and an oxygen dissolving mechanism, installation floating plates are fixedly installed on the two sides of the floating platform, a bearing plate is installed on the rear end face of the floating platform, and the floating platform, the installation floating plates and the installation floating plates form a riverway oxygenation base station. One oxygen injection mechanism used for increasing the oxygen content of water liquid in a river channel is installed at the bottom of each installation floating plate, the sterilization mechanism used for reducing the microorganism content of riverwater is installed at the bottom of the floating platform, and the oxygen dissolving mechanism used for increasing the dissolved oxygen content of the water liquid in the river channel is installed at the bottom of the floating platform. The riverway oxygenation device and the oxygenation method thereof have the advantages that the mixing contact area of air and water is increased, and the stability is good.

Description

technical field [0001] The invention relates to the technical field of river aeration, in particular to a river aeration device and an aeration method thereof. Background technique [0002] With the rapid development of the economy and the acceleration of urbanization, the problems of river water pollution and ecological degradation in many cities in my country are very prominent. In order to protect water resources and solve the problem of river pollution, people usually use oxygen-increasing aeration devices to treat river sewage , this method is to increase the oxygen in the water and increase the oxygen needed for the growth of plants and animals in order to ensure the ecology of the water. At present, mechanical oxygenation is mainly to provide high-content water to the polluted river water mechanically or through water and water. The method of effectively contacting air to continuously replenish oxygen to the water body increases the dissolved oxygen in the water body. ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing aerators used in river water raise the water through an impeller, stir the water body to produce splashes, and rely on the centrifugal force generated by the rotation to make the upper water body diffuse to the surrounding, and the lower water body fills the gap to form the water body up and down circulation, the oxygen content After the higher surface water enters the bottom layer, it can effectively improve the dissolved oxygen status of the bottom water body, but the oxygenation efficiency of most traditional wind wheel aerators is low, and the water body can only be raised by the impeller and added by air. Large contact to achieve the purpose of oxygenation, the dissolved oxygen in the water body is limited, and it is still prone to high-yield floating head hypoxia, which will cause the flood of microorganisms in the river water and cause a large number of fish and shrimp to die
