Embodiment 1

[0052] Such as figure 1 A kind of aeration system for repairing black and odorous water bodies that can increase water circulation is shown, including a water inlet device 1 arranged on the water surface for extracting black and odorous water bodies, an oxygenation system connected to the water inlet device 1, and an oxygen enhancement system connected with the water inlet device 1. Drain unit 4 for oxygen system connection;

[0053] The oxygenation system includes a magnetized mixing device 2 for increasing the concentration of dissolved oxygen, and a hybrid ultrasonic device 3 connected to the magnetized mixing device 2 for pressurizing the water body;

[0054] Such as figure 2 As shown, the magnetization mixing device 2 includes a protection box 20 arranged on the ground, a cutting waterway 21 movably installed in the protection box 20, an electromagnetic field generator 22 arranged in the protection box 20 and located on both sides of the cutting waterway 21 , and a cut...

Embodiment 2

[0080] The difference from Embodiment 1 is that the ejector 302 can eject the gas provided by the air booster pump 303, and the angle between the jet flow direction of the gas and the water flow direction is 50°;

[0081] Such as Figure 7 As shown, the water inlet device 1 includes a floating plate 10 fixed on the water surface, a sewage storage tank 11 arranged at the center of the floating plate 10 and opening above, a filter cartridge 12 arranged at the lower end of the sewage storage tank 11, and one end communicated with the filter cartridge 12 , the negative pressure pump 13 that the other end communicates with the cutting water pipe 211, the rotating water wheel 14 that is arranged on the floating plate 10 and is positioned at both sides of the sewage tank 11, and provides power to the rotating water wheel 14 to transport the black and odorous water to the storage tank. The power unit 15 in the dirty tank 11;

[0082] The dirt storage tank 11 is provided with a first ...

Abstract

The invention relates to the technical field of black and odorous water body aeration, and particularly discloses an aeration system capable of increasing water flow circulation and used for black and odorous water body remediation. The system comprises a water inlet device arranged on the water surface and used for pumping black and odorous water bodies, an aeration system body connected with the water inlet device and a drainage unit connected with the aeration system body. The aeration system body comprises a magnetization mixing device and a mixing ultrasonic device; the magnetization mixing device comprises a protection box body arranged on the ground, a cutting water path movably installed in the protection box body, electromagnetic field generating devices arranged in the protection box body and located on the two sides of the cutting water path, and a cutting power module arranged on the protection box body and used for providing magnetic induction line cutting power for the cutting water path. The system can be used for solving the problems of poor treatment effect and low efficiency caused by less increase of soluble oxygen content in the black and odorous water body repaired by an aeration system.

Description

technical field [0001] The invention relates to the technical field of oxygenation for black and odorous water bodies, in particular to an oxygenation system for repairing black and odorous water bodies that can increase water circulation. Background technique [0002] Black and odorous urban rivers have become a common pollution problem in many large and medium-sized cities in my country. It is of great significance to explore its causes and mechanisms. Black and odorous water bodies have attracted widespread attention. This kind of sewage seriously reduces the aesthetic feeling of the city, affects the creation of a good urban atmosphere, and also has unnecessary negative effects on the daily life of residents. Black and odorous rivers are a serious water pollution phenomenon in the process of urbanization in my country. The main reason is that the organic matter in the water body consumes more oxygen than reoxygenation during the decomposition process, resulting in an ano...
