Abstract:

短程硝化/厌氧氨氧化‑硫自养反硝化实现晚期垃圾渗滤液深度脱氮的装置与方法,属于高氨氮废水生物脱氮领域。晚期垃圾渗滤液首先进入短程硝化/厌氧氨氧化反应器,进水NH4+‑N被氧化为NO2‑‑N,生成的NO2‑‑N在NH4+‑N作为电子受体条件下被厌氧氨氧化原位还原去除。厌氧氨氧化过程每去除1molNH4+‑N将代谢产生0.26molNO3‑‑N,因此大量NO3‑‑N在短程硝化/厌氧氨氧化反应器内积累,难以满足垃圾渗滤液排放标准;含有NO3‑‑N的出水和外加硫离子同时引入硫自养反硝化反应器,在确保进水S/N质量比大于等于1.42条件下,厌氧氨氧化产生的NO3‑‑N被硫自养反硝化菌还原为N2,实现晚期垃圾渗滤液的深度脱氮处理。本发明解决了晚期垃圾渗滤液脱氮效率低、出水总氮高的问题,并极大降低了剩余污泥产量。
