Mathematical Model Research of Bottom Sediment Adsorption and Release in Liyun River at Huai'an of Jiangsu Province

摘要

The spatial distribution of heavy metal in sediment is shown based on the collection and analysis of the sample in Liyun River at Huai'an of Jiangsu province.Heavy metal release law in the water column of the Yangtze River with the quiet place condition is shown through the simulation of experiments.Finally,adsorption and release model of cadmium in the river is built and yields the experimental testing,providing basis of bottom sediment handling and desilting.
