中文摘要 | 本研究乃利用部分硝化之原理,藉由氧氣供應量之控制,將氨氮氧化成亞硝酸鹽氮而非硝酸鹽氮,所使用之薄膜生物反應器是以矽膠管做為供氧系統,來取代傳統之曝氣系統。研究發現本系統極適於部分硝化反應之進行,且具有相當高的穩定性,以平均約510 mg/L NH₄[90a7]-N之高氨氮濃度合成廢水進行24小時之批次實驗,槽內液相中NH₄[90a7]濃度漸減而NO₂¯濃度漸增,NO₃¯則於反應時間內幾乎沒有形成,且最終槽內液相NH₄[90a7]-N/ NO₂¯-N之比值趨近於1,因此,若後續以Anammox程序進行脫氮,則不僅大幅減少氧氣需求量,更可提升生物脫硝速率,降低操作成本,頗具實用性及發展潛力。 |
英文摘要 | This research is based on the principle of partial nitrification, with the control of oxygen supply; the ammonia is oxidized into nitrite but not nitrate. The membrane bioreactor used in this research is to utilize silicon tube as the air supply system. It is indicated that this system is feasible for partial nitrification reaction, and have quite high stabilities. The batch experiments of 24 hours were carried on with the synthetic wastewater of high concentration of ammonia nitrogen. The concentration of NH₄[90a7]-N was reduced gradually and NO₂¯-N was cumulative with time, and NO₃¯-N scarcely forms in 24 hours of reaction time. At the end of reaction, the NH₄[90a7]-N/ NO₂¯-N ratio approached to 1. So if Anammox process is the follow-up denitrification reaction, this system not only can save the demand of the oxygen, but raise the reaction rate of demitrification and reduce the operation cost effectively. This type of reactor has much practicability and development potentiality for biological dnitrification process. |
