In order to determine the removal efficiency of COD,TP,TN,cations and anions by plant,and illustrate the transfer mechanism of nitrogen-containing pollutants,Thalia dealbata was used to treat the water samples collected from an urban river in Guangzhou and a lake at Jinan University.The results indicated that T.dealbata could improve the removal ratios of COD,TP and TN.After the urban river water samples were treated for 144 h,the concentrations of TN,CODCr and TP were decreased from 11.15mg·L-1,45mg·L-1 and 1.17mg·L-1to 3.21mg·L-1,15.8mg·L-1 and 0.53mg·L-1,respectively.After the lake water samples were treated for 144 h,they were reduced from 4.50mg·L-1,36mg·L-1 and 0.25mg·L-1 to 2.31mg·L-1,11.7mg·L-1 and 0.03mg·L-1,separately.Moreover,the indigenous microorganisms and T.dealbata could remove NH4+ effectively,and induced nitrosification and nitrification.However,they did not change the levels of Cl-,SO42-,Na+,K+,Mg2+and Ca2+.
