Improving the Aquaculture Water by Multe-Oxidants That Generate by Electrochemistry Technology
Nitrogen oxide such as ammonia and nitrite were critical species of pollutant in traditional aquaculture and the water-exchange method was used to deal with deteriorate of cultivation water. Based on the substantial development of environment, the tendency of aquaculture will tend to use recirculation water system. Therefore, the aim of this research was to realize the improvement of cultivation water and reduce the influence strike against the environment by multe-oxidants. Hence, we use synthetic water to simulate real aquaculture for basic test and simplification, and try to find out the optimum dose ratio of multe-oxidants in different concentrations of ammonia and nitrite. Compared with the reference, the multe-oxidants was more efficient than ozone for ammonia removal, and the removal rate was proportional to the dose ratio. The similar result has been observed in nitrite removal, and the fully removal could be achieved at dose ratio 1:2. Furthermore, the reaction balance could be achieved in 5 minutes when using multe-oxidants to treat ammonia and nitrite.
