基于MABR的压裂返排液处理及微生物群落研究

文章导读

摘要压裂返排液含有多种复杂有机物,毒性高、盐度高以及可生化性差。设计了1个三级MABR系统用于压裂返排液的处理,该系统在最适宜运行参数下表现出优异的除碳脱氮性能,出水经过芬顿试剂处理后满足污水综合排放二级标准。MABR系统对COD、NH⁺₄-N和TN的去除率分别达到79.30%、96.06%和75.61%。微生物分析表明MABR生物膜富集了丰富的功能菌群,Proteobacteria(变形菌门)、Bacteroidetes(拟杆菌门)是生物膜中的优势菌群。阐明了MABR处理压裂返排液的技术可行性,为MABR在处理相关废水中的应用奠定了基础。

Abstract： Fracturing flowback wastewater (FFW) contains a variety of complex organic substances with high toxicity, high salinity and poor biodegradability. In this study, a three-stage membrane-aerated biofilm reactor (MABR) system was designed for the treatment of FFW. The system showed excellent carbon and nitrogen removal performance under the optimal operating parameters. The effluent from MABR system treated by Fenton reagent met the secondary standard of integrated wastewater discharge. The removal rates of COD, NH⁺₄-N and TN by MABR system were 79.30%, 96.06% and 75.61%, respectively. Microbiological analysis showed that MABR biofilm was enriched with abundant functional flora, in which Proteobacteria and Bacteroidetes were the dominant flora. This study demonstrated the technical feasibility of MABR treatment of FFW, and laid a foundation for the application of MABR in the treatment of related wastewater.
