A river pollutant removal device

Abstract

The invention discloses a river pollutant removal device. The upper section of a vertical hollow pipe is positioned on the water surface of a river, and the lower section of the vertical hollow pipe stretches into the water surface of the river; the top opening of the vertical hollow pipe is sealed; one end of each of 2-4 bent hollow pipes stretches into the sealed top opening of the vertical hollow pipe and is fixedly connected with the vertical hollow pipe; each bent hollow pipe is downwards bent by a certain angle from the top opening of the extended vertical hollow pipe; the lower part of each bent hollow pipe is positioned on the water surface and is connected with a conical cylinder of the vertical hollow pipe by virtue of a bearing; steps are formed in the surface of the outer side of the conical cylinder; silver phosphate catalysts are fixedly arranged on the outer surfaces of the steps; the lower edge of the conical cylinder outwards horizontally extends to form a platform; a first blade is fixed at the outer edge of the upper surface of the platform; and a second blade is fixedly arranged on the lower section of the vertical hollow pipe below the water surface. Electrodynamic force is not needed in the whole process, and the aim of filling oxygen can be achieved by virtue of river water flow; and moreover, due to deep river water, the vertical hollow pipe can be lengthened, so that the river water on the whole section can be uniformly filled with oxygen.

Description

technical field [0001] The invention relates to a river channel pollutant removal device, which belongs to the technical field of sewage treatment in environmental protection. Background technique [0002] At present, urban and rural rivers are seriously degraded due to pollution and ecosystems, and water environment problems are becoming more and more serious. Most rivers are seriously polluted and eutrophic, resulting in a severe environmental and ecological situation. Aeration refers to artificially passing air into the biochemical aeration tank through appropriate equipment to achieve the purpose of oxygenation. Aeration not only makes the liquid in the pool contact with the air to oxygenate, but also accelerates the transfer of oxygen in the air to the liquid due to the agitation of the liquid, thereby completing the oxygenation; in addition, aeration also prevents the suspension of the pool from sinking, and strengthens the organic matter and microorganisms in the wate...

AI Technical Summary

Problems solved by technology

[0005] However, there is currently no suitable aeration and oxygenation device for the river, because the water volume of the river is large, if the existing aeration device is used for aeration, if the aeration is continued 24 hours a day, the electric power cost required for aeration will be very high
