摘　　要：对A/O-MBR工艺处理高COD、高氨氮餐厨废水进行了研究.结果表明,在为期140d的运行过程中,出水平均COD、NH4＋-N、TN分别为277、2.16、271 mg/L,平均去除率分别达到95.68％、99.78％、79.43％;当硝化液回流比为300％,反应器进水补充甲醇作为碳源时,出水平均COD、NH4＋-N、TN分别为275、2.10、71 mg/L,平均去除率分别达到95.35％、99.77％、95.01％;当污泥质量浓度维持在9～13 g/L时,可减缓膜污染的速度,TMP的增长较为缓慢.Research on the A/O-MBR technology used for treating food wastewater with high COD and high ammo- nia-nitrogen has been accomplished. The results indicates that in a 140 d operation process,the average effluent COD,NH4＋-N and TN are 277,2.16 and 271 mg/L, respectively,and the average removing rates reach 95.68%, 99.78% and 79.43% ,respectively. The average effluent COD, NH4＋-N and TN are 275,2.10 and 71 mg/L, respec- tively and the average removing rates reach 95.35%, 99.77% and 95.01%, respectively, when the nitrification liquid return ratio is 300% and CH3OH is added to the reactor influent as carbon source. When the mass concentration of sludge keeps at 9-13 g/L, the speed of membrane fouling could be slowed down, and the increase of TMP is slower.
