Abstract


In order to provide theoretical and scientific basis for the application of artificial aquatic plants in the black-odor river, parameters optimization experiment was undertaken to remediate artificial wastewater using artificial aquatic plants. After 25 days’ experiment, the results showed that the optimum operating parameters of dissolved oxygen was in 3.0-5.0mg/L, and that of pH was in the range of 8.0 to 8.5 in the low concentration of wastewater. And the removal rates of COD and NH4 +-N were 95.92% and 19.67% in low concentration of wastewater, 88.00% and 41.96% in the dissolved oxygen content of 3.0-5.0mg/l, 84.10% and 39.42% in pH 8.0-8.5, respectively.
