Abstract:将微孔炭管曝气膜置于厌氧折流板反应器(ABR)隔室内,构建一种新型复合式生物反应器(HMABR),通过MABR与ABR的耦合作用强化ABR处理污水的功能,降解其中COD、NH+4-N和TN.结果表明,将驯化好生物膜的炭管曝气膜加入反应器第3隔室后,在膜内腔气压0.025MPa, HRT=24 h,进水COD为2 000 mg/L, NH+4-N为50 mg/L的条件下,系统发生同时硝化反硝化,出水COD、NH+4-N分别从加膜前的156 mg/L、36mg/L左右下降到45 mg/L、6mg/L左右, TN去除率达到87.66%,第3隔室挥发性脂肪酸(VFA)减少77.12%,总产气量减少30%.
