摘要
实验探索了高MLSS(溶液悬浮固体浓度)下多孔颗粒载体—膜生物反应器发生短程硝化、反硝化的可能性。研究了溶解氧(DO)、C/N、氨浓度及氨负荷、pH等因素对短程硝化、反硝化和TN去除的影响。实验发现,当控制pH=7.5、DO=1.0mg/L、C/N为6时,该反应器能同时达到较高的NH4+—N和TN出除率。
The possibility of shortcut nitrification - denitrification in porous granulated carrier - membrane bioreactor under high MISS was explored. This paper studied on the influence of dissolved oxygen （DO）, C/N, ammonia density, ammonia load and pH on shortcut nitrification - denitriflcation and the removal of nitrogen. The experimental results showed that the NH4^＋ -N and TN could be removed effectually at the same time if the conditions were controlled under C/N ratio of 6, DO of 1.0 mg/L and pH of 7.5.
