【摘要】 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、NH4+-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0.025 MPa,HRT=24 h,进水COD为2000 mg/L,NH4+-N为50 mg/L的条件下,系统发生同时硝化反硝化,出水COD、NH4+-N分别从加膜前的156 mg/L、36 mg/L左右下降到45 mg/L、6 mg/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%.更多还原

【Abstract】 New type hybrid biological reactor was developed by initiating the carbon membrane aeration in ABR which was augmented with carbon aerated membranes to improve wastewater treatment by removing COD,（NH⁺₄-N） and TN.The results showed that on the conditions of intra-membrane pressure of 0.025 MPa,HRT 24 h,influent COD（2?000）（mg/L）,（NH⁺₄-N） 50（mg/L）,simultaneous nitrification and denitrification was happened,and COD and（NH⁺₄-N） decreased from 156（mg/L）,36 （mg/L） to 45（mg/L）,6（mg/L） respectively after the membrane aeration with biofilm was initiated in the third compartment of ABR.TN removal reached 87.66%,and VFA and biogas was decreased by 77.12% and 30%,respectively.更多还原
