    Abstract
  • The simulated Grade I (A) effluent based on the Standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) was used as the inlet of wetland. Under the intermittent operation, the effects of hydraulic load and water flow mode on the pollutants removal of the new-type integrated vertical flow constructed wetland simulation system were investigated. The effect of plant planting on pollutants removal was also investigated. The results showed that the optimal operation hydraulic load of the new-type integrated vertical flow constructed wetland simulation system was 0.36 m3/(m2·d), the best way was vertical upward flow type (UVCW), and the effluent concentrations of total phosphorus (TP) and chemical oxygen demand (COD) met Grade Ⅳ requirements of Environmental Quality Standard for Surface Water (GB 3838-2002). With plants planting of Phragmites australis and water hyacinth, the constructed wetland had a significant effect on pollutants removal. The removal rates of total nitrogen (TN), TP, ammonia nitrogen (NH4+-N) and COD could reach 72.20%, 72.00%, 81.13% and 75.01%, respectively, and the effluent TP, NH4+-N and COD concentrations achieved Grade Ⅳ water quality standards. When the new-type integrated vertical flow constructed wetland was applied, it was recommended to set the hydraulic load to 0.36 m3/(m2 ·d), choose UVCW flow mode, and implement complex planting to ensure the stable operation of the wetland and high removal effect of pollutants.
