INFLUENCE OF TYPE AND DOSING LOCATION OF CARBON SOURCE ON WATER QUALITY OF SUBMERGED ZONE IN PYRITE-BASED BIORETENTION SYSTEMS

  • 摘要: 在生物滯留設施內構建淹沒區并添加碳源是目前廣泛采用的雨水強化脫氮方式,這使得淹沒區成為反硝化作用發生的主要場所,并顯著影響生物滯留設施脫氮效能。但是目前尚無研究清晰揭示生物滯留設施中碳源的種類和位置對淹沒區水質的影響?;谔嵘S鐵礦同步脫氮除磷的能力,在黃鐵礦基質生物滯留設施中通過改變碳源的種類(玉米芯、稻殼、樹皮)和添加位置探究了其對淹沒區水質的影響。結果顯示,3種碳源對強化NO3--N的去除的能力順序為樹皮>稻殼>玉米芯,且樹皮不會造成NH4+-N去除效率的下降。對淹沒區水質的進一步研究發現,添加樹皮后淹沒區NH4+-N、PO43--P濃度更低,且NO3--N去除速率更快。碳源添加在覆蓋層促進了NH4+-N和PO43--P去除,但NO3--N去除率略微下降。碳源添加在覆蓋層可以維持淹沒區中更低且穩定的NH4+-N濃度,并提供適宜的COD使NO3--N濃度不斷下降。當碳源添加在包氣帶和覆蓋層時反硝化主要發生在干旱期間,而碳源添加在淹沒區時反硝化作用主要發生在降雨期間。
