炭管曝气膜强化厌氧折流板反应器功能的研究

Innovative Application of Carbon Tube Aerated Membranes to Enhance Anaerobic Baffled Reactor for Wastewater Treatment

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%.

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. NH4^＋ -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, NH4^＋ -N 50 mg/L. simultaneous nitrification and denitrificatlon was happened, and COD and NH4^＋ -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.
