AbstractAn ecological engineering project, with large-scale utilization of Eichhornia crassipes (coverage area similar to 4.3 km(2)) for pollution control in an open ultra-eutrophic lake, Lake Caohai, was first implemented in 2011. In this study, the efficiency of N removal using E. crassipes in the lake was evaluated. After E. crassipes was planted in May, the concentrations of TN and NH4+ in Waicaohai, the main part of Lake Caohai, were significantly decreased within a month, and then, remained stable from June to November, 2011, although the lake had received waste water continuously from river inlets. The average concentrations of TN, NH4+-N and NO3--N in water of Xi Yuan Channel (outlet) were reduced to 33, 0.02 and 0.8 mg L-1 from 13.8, 4.7 and 5.8 mg L-1 in river inlets, respectively. The DO levels in 2011 were not decreased, but concentrations of TN and NH4+ were significantly reduced when compared with the historical data from 2007 in the lake. Assimilation by E. crassipes was the main pathway to remove N in Lake Caohai, accounted for 52% of the total N influent (936 t), or 64% of the removed N (761 t). These results indicated that large scale utilization of E. crassipes for removal of N in the eutrophic lake is practicable. (C) 2013 Elsevier Ltd.
