Abstract

Abstract

Sediment is a vital component of river and lake aquatic ecosystems, the repeated migration of pollutants between the sediment and overlying water bodies has become the crux of water environment management. This experiment studied the coupling of submerged plants and benthic animals to purify sediment to reduce the impact of sediment pollutants on water bodies. The research showed that the highest performance in removal of pollutants from sediment was achieved when combining 50% sediment coverage of Vallisneria natans with 2 kg/m² of freshwater mussels. The removal rates were 12.2% for organic matter, 25.3% for NO^-₂-N, 29.1% for NO^-₃-N, 54.4% for NH⁺₄-N, and 16.20% for TP. The removal rates of organic matter, TN, NO^-₂-N, NO^-₃-N, NH⁺₄-N and TP were 29.4%, 29.8%, 86.5%, 67.1%, 70.2%, 28.2% respectively, when adding biochar with 5% dry weight of sediment to the sediment, under 20 ℃. When aeration was conducted and the aeration rate was 6 L/min, the removal rates of organic matter, TN, NO^-₂-N, NO^-₃-N, NH⁺₄-N and TP in the sediment of the combination reached 23.5%, 39.1%, 92.1%, 77.7%, 71.8% and 17.3%, respectively.
