臭氧对大菱鲆半封闭循环水养殖系统水质净化研究
Effect of ozone on the purification of water in partial-reused aquaculture system for turbot (Scophthalmus maximus)
摘要
Abstract
Ozone can sterilize, oxidize, remove algal and improve water quality, and is widely used in kinds of waste water treatment. But there' s limited knowledge about the application of ozone in marine aquaculture. The effect of ozone on water quality in partial-reused aquaculture system for turbot (Scophthalmus maximus ) is studied by adding ozone to aquaculture system at the concentration of 0. 26 mg/L. The treatment group results showed that; total suspended solids can be effectively removed at 59% , and it keeps total suspended solids in the range of 8 mg/L, can effectively increase the concentration of dissolved oxygen of 8. 38 mg/L each cycle. In treatment group, 18% ammonia nitrogen, 8% nitrite nitrogen, 94% heterotrophic bacteria can be removed. The application of ozone to marine aquaculture system can significantly improve water quality, and will be widely extended in aquaculture waste water treatment.关键词
