Study On The Pollution Characteristics Of The Sediments In Huainan Segment Of Huaihe River

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.
