Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to a sterilization, disinfection, and oxygen-enriched water aquatic seedling cultivation system. Background Technology

[0002] Dissolved oxygen in aquaculture water plays a crucial role in ensuring fish health, reducing harmful substances such as ammonia nitrogen and hydrogen sulfide, and maintaining normal fish growth. However, directly using air stones or nanotubes for oxygenation in aquaculture ponds generates strong airflows that break up uneaten fish food and feces, increasing pollutant levels and accelerating water quality deterioration. In nursery ponds, some fish and shrimp fry are naturally timid, and excessive noise from oxygenation can frighten them, causing them to cluster excessively, hindering observation of their behavior and feeding during production. To effectively address these problems encountered in aquatic seedling cultivation, it is urgent to explore new aeration models for aquatic seedlings.

[0003] In addition, during the aquaculture process, pathogens will be generated in the aquaculture water, which need to be killed. However, using chemical reagents to kill these pathogens will affect the water quality. Utility Model Content

[0004] The purpose of this invention is to provide a sterilization and disinfection oxygen-enriched water aquatic seedling cultivation system. This system does not affect water quality during sterilization, and it oxygenates the aquaculture water without affecting the normal growth of fish and shrimp fry.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A sterilization and disinfection system for oxygen-enriched aquatic seedling cultivation includes a seedling pond, a controller, a drainage pipe, a return pipe, an ozone generator, a gas-liquid mixing pump, a gas-liquid mixing tank, an ozone removal pipe, an ultraviolet lamp, an ozone content sensor, an oxygen content sensor, a water-oxygen mixing tank, a liquid oxygen tank, and a water pump. The drainage outlet of the seedling pond is connected to one end of the drainage pipe, and the other end of the drainage pipe is connected to the inlet of the gas-liquid mixing pump. The ozone generator is connected to the air inlet of the gas-liquid mixing pump via an ozone conduit. The discharge outlet of the gas-liquid mixing pump is connected to the inlet of the gas-liquid mixing tank via the gas-liquid mixing pipe. The discharge outlet of the gas-liquid mixing tank is connected to one end of the ozone removal pipe. The other end of the oxygen removal pipe is connected to the water-oxygen mixing tank, which is connected to the inlet of the seedling pond via a return pipe. The ultraviolet lamp is installed inside the ozone removal pipe, and the water pump is located on the return pipe. The ozone content sensor is used to detect the ozone content in the water at the outlet of the ozone removal pipe, and the oxygen content sensor is used to detect the oxygen content in the water in the seedling pond. The liquid oxygen tank is connected to the oxygen distributor in the water-oxygen mixing tank via an oxygen supply pipe, and an oxygen supply solenoid valve is installed on the oxygen supply pipe. The ozone content sensor and the oxygen content sensor transmit data to the controller, which controls the on / off operation of the ultraviolet lamp, the ozone generator, and the oxygen supply solenoid valve.

[0007] Furthermore, a filter screen is installed at the water inlet of the seedling pond.

[0008] Furthermore, a drain pipe is provided on the bottom side of the seedling pond, and a valve is provided on the drain pipe.

[0009] Furthermore, the ultraviolet lamps are provided in two sets: one set of ultraviolet lamps is located at the top of the ozone removal tube, and the other set of ultraviolet lamps is located at the bottom of the ozone removal tube.

[0010] Furthermore, the ozone removal tube has a cuboid structure.

[0011] Furthermore, the seedling pond is surrounded by a fence.

[0012] The beneficial effects of this utility model are as follows: This application adopts an external aeration and regulation method, which avoids the airflow generated during the aeration process from breaking up uneaten feed and feces, reducing the content of harmful substances in the seedling water, and improving the water quality of the seedling water. At the same time, it reduces the noise in the seedling pond, improves the breeding environment, effectively alleviates the phenomenon of excessive fish concentration, and is conducive to observing the dynamics of seedlings and feeding during the production process.

[0013] This application uses a circulating water ozone sterilization method. After sterilization, ultraviolet lamps are used to decompose and remove ozone in the water, so the sterilization process will not affect the water quality. Attached Figure Description
