不同氧环境中黑藻腐解过程及对水体-底泥碳、氮、磷的影响
DOI: 10.3724/SP.J.1145.2013.00484, PP. 484-488
Keywords: 沉水植物,黑藻,腐烂分解,营养盐,溶解氧
Abstract:
为了解不同溶氧条件沉水植物衰亡分解对水体以及底泥碳、氮、磷的影响，在实验室模拟条件下研究了不同氧环境下沉水植物黑藻（hydrillaverticillataroyle）分解过程中碳、氮、磷的释放，并探究沉水植物分解中，由于氧环境的改变对水体与底泥碳、氮、磷的影响.结果表明：好氧条件促进了黑藻腐烂分解，以及碳、氮的释放，但对磷的释放影响不大.同时，好氧条件明显降低了水体氨氮的含量，减慢了水体了硝酸盐氮的去除率.而低氧条件加快了硝酸盐氮的去除率，但是氨氮含量较好氧条件明显增加.因此，可以考虑在沉水植物腐解前期，氨氮迅速增大时适当曝气以降低水体氨氮含量.一段时间后停止曝气，此后沉水植物分解过程增强了水体反硝化作用，加快水体硝酸盐氮的转化，促进氮素以气体形式移出水体.
