Abstract:
On the basis of source pollution control, a combined process of fabricated permeable barrier (PB), anaerobic filter (AF), biological aerated filter (BAF) and integrated constructed wetland (ICW) was used for blackodorous water governance of Xinhe River in Fengxi New City. After four months of operation and commission, the river water quality was significantly improved. When the average upstream concentrations of COD, BOD5, TP and NH3-N were 44.98 mg/L, 9.39 mg/L, 0.91 mg/L and 7.71 mg/L, the average downstream concentrations were reduced to 24.71 mg/L, 2.88 mg/L, 0.35 mg/L, and 1.33 mg/L, respectively. DO and transparency were increased from 2.3 mg/L, 13 cm to 5.3 mg/L, 40 cm, respectively. They could meet the standard for level Ⅳ-Ⅴ in Environmental Quality Standards for Surface Water(GB 3838-2002). The effective treatment performance indicated that combined process was suitable for treatment of polluted river with poor biodegradability and limited restoration space inside and outside of river channel.
