transportation and transformation of a main contaminant (ammonia nitrogen) in the Taihu Lake sediment through a clayey soil layer are studied experimentally. The permeability coefficient and diffusion coefficient under different pressures are determined through the laboratory tests of stimulation test of infiltration and dynamic soil column test. The adsorption coefficient of ammonia nitrogen to clay soil is also obtained through the static adsorption test. The test results show that the ammonia nitrogen is mainly adsorbed and obstructed by the clayey soil layer in a facility for the dredged sediments from Taihu Lake.
