摘　　要：研究了以葡萄糖为碳源曝气生物滤池在不同运行条件下(进水浓度、气水比、填料高度)去除COD的效能。结果表明:当进水COD浓度为500 mg/L时,4个BAF的出水波动相对较大,进水为280 mg/L和100 mg/L时出水相对稳定,故BAF进水浓度不宜过大,最佳浓度为100~300 mg/L;当进水气水比为11∶1时,4个BAF的出水稳定性最佳,而且BAF3和BAF4的去除率也最高,分别达到了70.51%和83.40%。通过进入参数P,以及4个BAF的沿程出水情况,得出结论,在填料高度不高于20 cm时出水最为稳定。The COD removal efficiency of glucose-based biological aerated filter(BAF)under different operating conditions(influent concentration,gas water ratio and filler height)was studied.The results show that when the influent COD concentration is 500mg/L,the effluent of the four BAFs fluctuates relatively large,and when the influent COD concentration is 280mg/L and 100mg/L,the effluent is relatively stable,so the influent concentration of BAF is not easy to be too high,and the optimal concentration is 100~300mg/L;When the ratio of air to water is 11∶1,the effluent stability of the four BAFs is the best,and the removal rates of BAF3 and BAF4 are the highest,reaching 70.51%and 83.40%respectively.By entering the parameter P and the water outflow along the four BAFs,the results show that the water outflow is most stable when the filler height is less than 20 cm.
