A novel hybrid aerating membrane-anaerobic baffled reactor (HMABR), based on the installation of aerating membrane into an anaerobic baffled reactor (ABR), to achieve simultaneous removal of nitrogenous and carbonaceous organic pollutants was developed in this study. The results demonstrated that after the installation of membrane module, total VFA and COD concentration in the HMABR effluent were decreased by 68.1 and 59.5% respectively, with increased nitrogenous pollutant remove efficiency by 83.5%, at influent COD concentration of 1600 mg/L and NH(4)(+)-N concentration of 80 mg/L. Fluorescence in situ hybridization (FISH) results of the aerating membrane biofilm showed that the biofilm stratification for the spatial profiles of ammonia-oxidizing bacteria, nitrite-oxidizing bacteria, aerobic heterotrophic bacteria, and denitrifying bacteria. The potential usage of HMABR widens the usage of aerobic-anaerobic combination technology for industrial wastewater treatment.
本研究开发了一种新型混合曝气膜-厌氧折流板反应器(HMABR),即在厌氧折流板反应器(ABR)中安装曝气膜,以实现含氮和含碳有机污染物的同步去除。结果表明,在进水COD浓度为1600 mg/L、NH(4)(+)-N浓度为80 mg/L时,安装膜组件后,HMABR出水的总挥发性脂肪酸(VFA)和COD浓度分别降低了68.1%和59.5%,含氮污染物去除效率提高了83.5%。曝气膜生物膜的荧光原位杂交(FISH)结果表明,生物膜在空间上呈现出氨氧化细菌、亚硝酸盐氧化细菌、好氧异养细菌和反硝化细菌的分层现象。HMABR的潜在应用拓宽了好氧-厌氧组合技术在工业废水处理中的应用范围。
