| 中文摘要: |
| 将日本马泽藻Mazzaella japonica、孔石莼Ulva pertusa、鼠尾藻Sargassum thunbergii、红毛菜Bangia fusco-purpurea、蠕枝藻Helminthocladia australis、扇形拟伊藻Ahnfeltiopsis flabelliformis 6种大型海藻培养在富含氮磷海水中72 h，分析海水中氨氮、硝氮和活性磷浓度的变化，目的在于比较它们对营养盐去除效果。实验结果表明，6种海藻对氮磷都有明显的去除作用，日本马泽藻和孔石莼对氨氮、硝氮和活性磷的去除效果最好，分别吸收了培养水体中氨氮初始总量的98.0%和97.1%、硝氮初始总量的76.9%和82.0%、活性磷初始总量的90.8%和86.9%。 |
| 英文摘要: |
| o investigate the removal efficiency of nutrient by macroalgae, six species of algae, including Mazzaella japonica, Ulva pertusa, Sargassum thunbergii, Bangia fuscopurpurea, Helminthocladia australis, and Ahnfeltiopsis flabelliformis, were cultured in natural seawater for 72 h, and then the concentrations of ammonia, nitrate, and phosphate in the culture media were measured respectively. The results showed that compared with the other species, M. japonica and U. pertusa showed much higher efficiency in removing all three nutrients. The percentages of the three nutrients absorbed by M. japonica and U. pertusa in 72 h were 98.0% and 97.1% of ammonia, 76.9% and 82.0% of nitrate，90.8% and 86.9% of phosphate, respectively. |
