Study on the Removal of Heavy Metals and Organic Pollutants in Water Bodies Through Various Aquatic Plants
The ability of different aquatic plants to remove heavy metals and organic pollutants from contaminated water bodies was investigated.Experimental analyses compared the efficiency of reeds,water hyacinths,and water lilies in mono-planting and inter-planting systems for the removal of pollutants such as lead,cadmium,mercury,benzene,and toluene.Findings reveal that reeds are particularly effective in removing heavy metals,while water hyacinths and water lilies show greater advantages in reducing organic pollutants and suspended solids.Moreover,variations in ecological flow significantly affect pollutant removal rates,with higher efficiency under increased flow conditions.Under high-flow conditions,pollutant removal efficiency significantly increased,providing a scientific basis for the pollution control of rivers and other water bodies.
