碱蓬对富营养化海水养殖水体中氮磷的去除研究
Study of the Removal of Nitrogen and Phosphorus from the Eutrophic Marine Aquaculture Waters by Suaeda Glauca
摘要
Abstract
In this paper, artificial simulation tests were used to set up purification experiments of eutrophic waters with five kinds of concentration gradient. Effects of a halophyte named Suaeda glauca on removal and purification of nitrogen and phosphorus in the aquaculture waters at different eutrophic levels were compared and studied. The results showed that Suaeda glauca could grow in the waters at lower eutrophic level. However, it could grow well in the waters at higher eutrophic level only after a certain adaption phase. Furthermore, Suaeda had a good purification effect on nitrogen and phosphorus in water, with initial concentrations of 0.68 ~8.02 mg/L and 0.00 ~3.12 mg/L reduced to be 0.37 ~2.36 mg/L and 0.00 ~1.70 mg/L respectively, as well as played a role in reducing the water salinity from the initial rate of 3.2% to 2.6% ~2.9%, providing scientific basis for profound study of the patterns and mechanisms of eutrophication aquaculture water remediation by use of halophytes.关键词
