摘　　要：借助序批式反应器(SBR),通过采用厌氧/好氧/缺氧(AOA)的运行方式来实现同步脱氮除磷.结果表明:AOA-SBR系统运行稳定后,磷酸盐和总氮的平均去除率分别可达97.77%和88.89%;对运行时间优化得到最佳运行工况为厌氧(含进水)1.5,h,好氧2.5,h,缺氧3,h,静置沉淀1,h以及排水闲置0.5,h.缺氧段外碳源浓度及投加方式试验结果表明,一次性投加优势明显,最佳投加浓度为60,g/L NaAc.Simultaneous nitrogen and phosphorus removal from wastewater was investigated in SBR operated in anaerobic/aerobic/anoxic（AOA）mode. The results show that after the AOA-SBR process was stably operated, the average phosphorus and total nitrogen removal efficiencies were 97.77% and 88.89% respectively. The optimum operating condition obtained by the running-time optimization was： anaerobic stage（including influent water time）1.5 h, aerobic stage 2.5 h, anoxia stage 3 h, static settlement stage 1 h and drainage idle stage 0.5 h. In addition, the experiment about the performance of different external carbon source concentration and adding model on anaerobic period shows that continuous feeding had no obvious advantage over disposable feeding, and continuous feeding consumes more energy. Therefore ,it would be best to use disposable feeding, and the best adding dosage was 60 g/L NaAc.
