- 摘要:
- 以灃西新城新河黑臭水體治理為目標(biāo),在控源截污等措施基礎(chǔ)上,采用裝配式濾墻/AF/BAF/復(fù)合流人工濕地組合工藝進(jìn)行系統(tǒng)治理。經(jīng)過4個(gè)月的運(yùn)行調(diào)試,新河水質(zhì)已得到明顯改善,上游來水COD、BOD5、TP、NH3-N平均濃度分別為44.98、9.39、0.91、7.71 mg/L的情況下,出水平均濃度分別降至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,達(dá)到《地表水環(huán)境質(zhì)量標(biāo)準(zhǔn)》(GB 3838—2002)Ⅳ~Ⅴ類水平。該技術(shù)在河道修復(fù)空間有限、原水可生化性差等污染河流治理中具有參考借鑒價(jià)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.
