- 摘要:
- 以沣西新城新河黑臭水体治理为目标，在控源截污等措施基础上，采用装配式滤墙/AF/BAF/复合流人工湿地组合工艺进行系统治理。经过4个月的运行调试，新河水质已得到明显改善，上游来水COD、BOD5、TP、NH3-N平均浓度分别为44.98、9.39、0.91、7.71 mg/L的情况下，出水平均浓度分别降至24.71、2.88、0.35、1.33 mg/L，DO、透明度由平均2.3 mg/L、13 cm上升至5.3 mg/L、40 cm，达到《地表水环境质量标准》（GB 3838—2002）Ⅳ~Ⅴ类水平。该技术在河道修复空间有限、原水可生化性差等污染河流治理中具有参考借鉴价值。
- 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 blackodorous 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.
