Method and device for killing cryptocaryon irritans cysts through hydroxyl radicals

Abstract

Provided are a method and device for killing cryptocaryon irritans cysts through hydroxyl radicals. The method is provided with a water storage tank, a couture pond, a high-frequency high-voltage power source, a modular oxygen activity fragment generator, an online oxygen activity fragment detector, a Venturi gas-liquid mixing and dissolving device, a liquid-liquid mixing and dissolving device, a TRO detector, a motor, an automatic rotary brush, a water pump, a valve, a gas pipeline and a liquid main pipeline. An air inlet of the modular oxygen activity fragment generator is externally connected with an oxygen source, and an oxygen activity fragment air outlet of the modular oxygen activity fragment generator is connected with the online oxygen activity fragment detector, and an air suction opening of the Venturi gas-liquid mixing and dissolving device in sequence. A water outlet of the water storage tank is connected with a water inlet of the water pump, a water outlet of the water pump is connected with a liquid inlet of the Venturi gas-liquid mixing and dissolving device, a liquid outlet of the Venturi gas-liquid mixing and dissolving device is connected with a liquid inlet of the liquid-liquid mixing and dissolving device, and a liquid outlet of the liquid-liquid mixing and dissolving device is connected with the TRO detector and a water inlet of the culture pond in sequence. The automatic rotary brush controlled by the motor is arranged in the middle of the culture pond, and a water outlet in the bottom of the culture pond is externally connected with sea water.

Description

technical field [0001] The invention relates to the fields of plasma chemistry, seawater aquaculture technology, marine environmental engineering and the like, in particular to a method and device for killing and stimulating Cryptocaryon cyst by hydroxyl radicals. Background technique [0002] Cryptocaryon stimuli is a kind of ciliate that causes "white spot disease" in marine fish. The disease is prone to outbreaks in water bodies with high stocking density, poor fluidity and rich organic matter content, and usually parasitizes tropical and subtropical marine fish. The skin, fins, gills, etc. of the fish will cause damage and dysfunction of fish organs, cause abnormal activity, epithelial hyperplasia, breathing difficulties and mechanical damage of diseased fish, cause a large number of fish deaths, and cause great harm to the mariculture industry. [0003] The life cycle of Cryptocaryon stimuli includes four stages: "trophoblast", "cyst precursor", "cyst" and "larvae". Tr...
