摘要
以海洋富营养化水体为处理对象、红树林植物秋茄为湿地植物,通过测定水体中的氮磷去除率,研究潜流型人工湿地系统对海洋水体脱氮除磷的效果.实验表明:潜流型人工湿地系统对中高浓度富营养化海水中总氮、总磷、氨氮、硝酸盐氮、亚硝酸盐氮和磷酸盐的平均去除率分别为76. 9%,46. 0%,69. 6%,71. 9%,54. 4%,74. 5%;对低浓度富营养化海水中各指标的平均去除率分别为79. 8%,64. 0%,80. 5%,72. 8%,31. 0%,76. 4%.总体上潜流型人工湿地对中高浓度和低浓度富营养化海水均具有良好的净化效果,其中,对低浓度富营养化海水的净化效果稍优于中高浓度富营养化海水.
To conduct research on nitrogen and phosphorus removal,the marine eutrophic water was treated by applying subsurface flow constructed wetland with the Kandelia candel of mangrove plant. The experimental results indicated that the average removal rates of TN,TP,NH4-N,NO3-N,NO2-N and PO4-P in medium high concentration marine eutrophic water are 76. 9 %,46. 0%,69. 6%,71. 9%,54. 4% and 74. 5%,respectively.Meanwhile the average removal rates of various indicators in low concentration marine eutrophic water are79. 8%,64%,80. 5%,72. 8%,31% and 76. 4%,respectively. In general,subsurface flow constructed wetland exerts good purification effect on both types of marine eutrophic water,with the purification effect on low concentration marine eutrophic water greater than that on medium high concentration marine eutrophic water.
