摘要 沉积物营养成分释放通量的模拟没有标准方法,现有研究中采用的方案均为自行设计,方案与结果差异明显。本文以藻苲淀为研究对象,选用差别较大的两种方案分别进行沉积物中COD、氨氮、总磷释放通量实验。通过模拟,沉积物中营养成分在前两天均表现为正释放,对水质的改善起到了负面作用。沉积物营养成分含量与各释放时间的释放速率没有明显相关性,并不是影响释放速率的直接因素,但其受泥水比的直接影响。 There is no standard method to simulate the release flux of sediment nutrients.The schemes used are self-designed,and there are differences in the schemes and results.In this paper,two different schemes were selected to test the release fluxes of COD,ammonia nitrogen and total phosphorus in sediments.Through the simulation experiment,the nutrients in the sediment showed positive release in the first two days,which was negative to the improvement of water quality.The nutrient content of sediment has no obvious correlation with the release rate of the release time,which is not a direct factor affecting the release rate,but is directly affected by the mud water ratio.
