【摘要】 近二十年来,淮河的污染日趋严重,即使在经过治理后,底泥仍能在很长时间内对水质产生影响。因此,底泥污染的研究和治理,是从根本上解决河流污染问题的重要途径之一。 借鉴湖泊水质评价方法,对淮河淮南段四个断面(峡山口、石头埠、姚家湾和胡大涧)的表层底泥及其间隙水和上覆水以及柱状底泥的地球化学指标(氮、磷、重金属等)进行了测试,并测定了柱状底泥的土质指标(粒径、粘性、矿物成分等),分析了氮、磷及同步浸提金属在底泥中的垂直分布规律和沿程分布规律及在表层底泥、间隙水和上覆水的分布特征,探讨了土质对底泥污染指标差异性的影响,可为淮河水质污染评价提供科学依据。更多还原

【Abstract】 Near the last 20 years, the contamination in Huaihe River is gradually serious. Even after the treatment, the sediment still can affect to the fluid matter creation in very long time. So the research and treatment on the pollution of sediment is one of the important methods to resolve the contamination problem of river by the root.Use the method of appraisement on lake quality for reference, test the geochemistry index (nitrogen, phosphorus, heavy metal elements etc.) of the sediment on surface layer and its back lash aqua and overlying water and the stanchion form sediment in four cross sections of the piece of Huainan of Huaihe river (Xiashankou, Shitoubu, Yaojiawan and Hudajian), and test the soil properties index (Particle size, stickiness, mineral component and etc.) of the stanchion form sediment, and analyzed the law of perpendicular distribution and the law of distribution along the distance of nitrogen, phosphorus and simultaneously extracted metals elements in the sediment, and inquired into the affection of the quality of soil to the otherness of sediment’s pollution index. The paper afford the reference of appraisement on contamination of water quality in Huaihe river.更多还原
