Application of ozone in aquaculture water treatment

来源: Release time: 2014/3/17 Views: 93 Source:

Ozone treatment of aquaculture water is extremely beneficial to the growth of fish, shrimp, and crabs, and the economic benefits are also very obvious. The aquaculture water is rich in organic matter, and the water quality is easy to cause problems. The spread of bacteria and viruses to fish and shrimp is also very rampant. In recent years, many shrimp ponds along the coast have lost production and a lot of wasteland.
In addition to sterilizing and inhibiting the infection and spread of fish and shrimp by virus bacteria in the treatment of aquaculture water, ozone can also degrade organic matter, reduce chemical oxygen demand (COD) and biochemical oxygen demand (BOD), and help to coagulate. Effect is a good measure for improving water quality. In recent years, water pollution has been severe, and diseases and large numbers of deaths caused by contaminated water are common. Ozone can degrade harmful substances such as NH3, SO2, and red tide toxin, which shows that the application of ozone technology in the breeding industry is necessary.
It has been reported that the treatment of aquaculture water with ozone can increase the fish pond fish production by more than 30%, and the shrimp pond shrimps can increase the production by more than 60%. The comparative test of fish, shrimp, and crab fry has increased the survival rate by more than 90%. The use of ozone in water generally kills bacteria in the water. If ozone is injected at a concentration of 0.5-1.2mg / L, all bacteria in the water can be killed. If used as a preventive agent, 0.5-0.7mg / L is sufficient.
