摘　　要：为提高废弃酒糟资源化利用附加值,实现对印染废水中亚甲基蓝(MB)的高效吸附降解,采用Massibacillus菌株和酒糟多孔炭材料(DGPC)制备了微生物固定化酒糟多孔炭材料(M-DGPC)。利用FTIR、SEM和EDS对M-DGPC的结构、形貌和元素组成进行了表征。通过批量实验考察了pH和盐度对M-DGPC吸附MB性能的影响,比较了在短期实验和长期循环利用中M-DGPC对MB的吸附和降解的性能。结果表明,在pH=6和盐度为1%的环境下,M-DGPC对水中MB的48h去除率分别达到97.0%和98.6%;M-DGPC在6次循环利用后对MB的去除率约为99%,经过8次循环利用后,对MB的去除率约为93%,且MB降解率约为50%。In order to improve the additional value of waste distiller's resource utilization and achieve the efficient adsorption and degradation of methylene blue(MB)in printing and dyeing wastewater,microbial immobilized porous charcoal(M-DGPC)was prepared from Bacillus massiliogabonensis strain and porous charcoal material(DGPC),and characterized by FTIR,EDS and SEM for analyses on its structure,morphology as well as element composition.The effects of pH and salinity on the MB adsorption performance of M-DGPC were investigated by batch experiments,and the adsorption and degradation performance of M-DGPC on MB were compared between short-term experiment and long-term recycling.The results showed that the removal rates of MB in water could reach 97.0%and 98.6%at pH=6 and salinity of 1%.In addition,The MB removal rate of M-DGPC was about 99%after 6 cycles,and about 93%after 8 cycles,with MB degradation rate of about 50%.
