High-density aquaculture oxygenation purification method and system

Abstract

The invention discloses a high-density aquaculture oxygenation purification method and system. The method comprises the following steps of producing ozone through an ozone generator, producing singlet oxygen through a singlet oxygen generator, producing hydrogen peroxide through a hydrogen peroxide generator, respectively inputting the ozone, the singlet oxygen and the hydrogen peroxide in a gas-water mixer through a metering pump, inputting aquaculture water to be treated in an aquaculture water pipeline in the gas-water mixer through a pipeline, and conducting gas-water mixing under 3-5 barometric pressure; leading the aquaculture water after treatment of the gas-water mixer in the aquaculture water pipeline; and enabling quantity of the aquaculture water treated by the gas-water mixer to be 10-15% of the total of the aquaculture water. The high-density aquaculture oxygenation purification method and system can improve water sterilizing effects, efficiently improve water dissolved oxygen and achieve mariculture on the base of obtaining using effects of the ozone in the aquaculture industry. Through optimization design of a gas-water mixing mode, cost is substantially reduced, and oxygenation purification requirements of an aquaculture environment with high density and small water are met.

Description

Technical field [0001] The invention relates to an oxygenation purification method and system for high-density aquaculture, in particular to intensive pond aquaculture, industrial closed recirculating aquaculture, imitating wild aquaculture such as fish and vegetable symbiosis aquaculture and other oxygenation and purification systems characterized by high-density small water bodies. Water quality optimization method and system. It belongs to the technical field of aquaculture. Background technique [0002] At present, pond intensive culture equipment, industrial closed circulating aquaculture equipment, and fish-vegetable symbiosis equipment are being promoted and applied in actual production. The production conditions of high-density small water bodies have stricter requirements on water quality. Ozone occurs in the aquaculture industry. The technology of oxygenation and water quality treatment with the core device has attracted great attention, but the existing ozone technolo...

Problems solved by technology

[0002] At present, pond intensive culture equipment, industrial closed-loop aquaculture equipment and fish and vegetable symbiosis equipment are being popularized and applied in actual production. The production conditions of high-density small water bodies have stricter requirements on water quality. In the aquaculture industry, ozone The technology of oxygenation and water quality treatment with the core of the ozone device has received great attention, but the existing ozone technology has poor sterilization effect in water, insufficient generation, unreasonable gas-water mixing, difficult removal of seawater bromide, and high overall cost of existing devices And equipment maintenance workload and other issues
