Advanced oxidation treatment device and method for controlling red tide plankton invasion on offshore culture zone

Abstract

The invention discloses an advanced oxidation treatment device and method for controlling red tide plankton invasion on an offshore culture zone, and belongs to the fields of a gas discharge advanced oxidation technology and a marine ecological environment protection application technology. The movable advanced oxidation treatment control device of the red tide plankton invasion of the offshore culture zone is formed by an integrated active oxygen radical generation device, a fence active oxide radical red tide plankton killing device and a vessel, wherein the integrated active oxygen radical generation device is disposed on the vessel; the fence active oxygen radical red tide plankton killing device is disposed on the sea by solid float cloth; and the integrated active oxygen radical generation device is connected with the fence active oxygen radical red tide plankton killing device at two ends of an active oxygen radical diffusion pipeline through a fiber reinforced PVC (polyvinyl chloride) soft connecting pipe. The active oxygen radical is injected into seawater so as to kill the red tide plankton; and therefore, the economic losses and ecological damage of the offshore culture zone caused by ocean red tide invasion are reduced.

Description

technical field [0001] The invention belongs to the technical field of gas discharge advanced oxidation technology and application of marine ecological environment protection, and relates to a device and method for preventing and controlling the invasion of marine red tide disasters, especially an advanced oxidation treatment device and method for preventing and controlling the invasion of red tide organisms in marine breeding areas . Background technique [0002] The 21st century is the most critical historical period for the development of my country's marine industry. While the marine economy continues to grow rapidly, the pollution of my country's coastal marine environment is also becoming more and more serious. One of its disastrous consequences is the frequent occurrence of red tides in my country's coastal waters. Not only It will cause damage to the marine ecological environment, and cause huge losses to people's lives and property, especially the marine aquaculture ...

AI Technical Summary

Problems solved by technology

The direct killing method is to use chemical agents to directly kill red tide organisms. Commonly used chemical agents include copper sulfate, quicklime, potassium permanganate, sodium hypochlorite, hydrogen peroxide, etc. The problem is that the chemical agents are highly toxic and can destroy coastal waters. Sea ecosystems are affected by tides and diffusion, and the effect on red tide organisms is short and the cost is high

However, since the method and device are sprayed to kill red tide organisms, they are easily affected by ocean tides and diffusion, the utilization rate of oxygen active particles is also low, and the production of hydroxyl radicals is also very low. The design of devices and methods is required, so the effect of treatment for preventing and controlling red tide biological infestation in sea farming areas is limited
