摘要:

以沣西新城新河黑臭水体管理为方针，在控源截污等办法根本上，采取拆卸式滤墙/AF/BAF/复合流人工湿地组合工艺进行系统管理。颠末4个月的运转调试，新河水质已获得较着改良，上游来水COD、BOD5、TP、NH3-N平均浓度别离为44.98、9.39、0.91、7.71 mg/L的环境下，出程度均浓度别离降至24.71、2.88、0.35、1.33 mg/L，DO、通明度由平均2.3 mg/L、13 cm上升至5.3 mg/L、40 cm，到达《地表水情况质量尺度》（GB 3838—2002）Ⅳ~Ⅴ类程度。该手艺在河流修复空间无限、原水可生化性差等污染河道管理中具有参考鉴戒价值。

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 we����appre 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.
