摘　　要：为了研究膜曝气生物反应器(MABR)在污水处理过程中的应用前景,探索氧气传质和脱氮规律,以昆山市某污水处理厂为研究对象,搭建了单级式MABR纯生物膜中试装置,在不同负荷条件下探究了MABR对污染物的去除效果,并对MABR在污水中的传氧性能进行了分析。结果表明,MABR在保证传氧的同时能够大幅降低曝气能耗,脱氮过程中有明显的同步硝化反硝化反应发生,而且污染物浓度越高越利于氧的高效利用;16S rDNA测序结果显示,MABR生物膜具有丰富的生物相,且以好氧微生物为主。To investigate the application prospect of membrane aerated biofilm reactor(MABR)in wastewater treatment,and explore the rule of oxygen mass transfer and nitrogen removal in the reactor,a single stage MABR pure biofilm pilot plant was built in a wastewater treatment plant in Kunshan.The pollutants removal performance of MABR was explored under different load conditions,and the oxygen transfer efficiency in wastewater was analyzed.MABR greatly reduced the energy consumption of aeration while ensuring oxygen transfer.Obvious simultaneous nitrification and denitrification took place in the process of nitrogen removal in the MABR,and the higher concentration of pollutant was conducive to efficient utilization of oxygen.The 16S rDNA sequencing showed that the MABR biofilm had diverse microbial species,and aerobic microbes were the dominant.
