Abstract

A bioremediation project was carried out in an open ultra-eutrophic lake, Lake Caohai in 2011 to determine whether large-scale cultivation of water hyacinths could improve water quality. The coverage of water hyacinths reached an area of 4.30 km2 (211.0 kt) which is approximately 50% of lake area by November. After the controlled growth of water hyacinths, the concentrations of TN, NH4+-N, and TP decreased significantly in May and remained relatively stable from June to November. The abundance of DO and the decrease of NH4+-N concentrations can be benefit for fishes and aquatic ecosystems, and the decrease of TP concentrations may contribute to the reduction of phytoplantkton biomass. Assimilation by water hyacinths accounted for 64% of the removed N and 108% of the removed P, with the extra P coming from the sediments. The results demonstrated that large-scale water hyacinths can successfully reduce nitrogen and phosphorus loads in a eutrophic lake.
