Nanobubble-and-hydroxyl-radical generator and system for processing polluted water without chemicals using same

Abstract

The present invention relates to a nanobubble-and-hydroxyl-radical generator and, more particularly, to a system for processing polluted water without chemicals comprising: an air supply unit; an inlet pipe, connected to the air supply unit, for introducing a fluid; the nanobubble-and-hydroxyl-radical generator, comprising a pump connected to the inlet pipe, a drive motor connected to the pump, rotary blades connected to the drive shaft of the drive motor, and fixed blades connected to the inner wall of the pump and disposed between the rotary blades; and a discharge pipe, connected to the nanobubble-and-hydroxyl-radical generator, for discharging a nanobubble-generated fluid, wherein the circumferential surface of the rotary blades or the fixed blades, or both, is formed to be inclined inone direction. As such, the present invention provides a nanobubble-and-hydroxyl-radical generator capable of further enhancing a dissolution rate in such a manner that the circumferential surface ofeach blade is inclined to induce a disturbance phenomenon of air and a fluid, thereby accelerating micronization and mixing of air and a fluid.

Description

technical field [0001] The present invention relates to micro-nano bubbles and hydroxyl radical generators, which can generate micro-nano bubbles and hydroxyl radicals and increase the dissolution rate of air or ozone in fluids by refining and mixing air and fluid, and the present invention About a system for treating polluted water without chemicals using said generator. Background technique [0002] In general, algae or aquatic plants living in wetlands or ponds (such as hazards in golf courses) depend on sunlight, water, and mineral nutrients (such as nitrogen or phosphorus dissolved in water) to spread. Mineral nutrients are provided in rain or irrigation water that flows into the pond. [0003] However, the above-mentioned mineral nutrients are constantly flowing, and algae or aquatic plants proliferate excessively and aggravate the eutrophication of the water body, correspondingly leading to the phenomenon of red tide. [0004] If the red tide phenomenon is not dealt...

Problems solved by technology

[0016] However, this system has the disadvantage that it requires a large pump power and that it requires a lot of installations including air compressors and pressure tanks

Therefore, it requires a large area and its cost is high
