摘要:采用宏组学分析技术研究了两家炼油厂电脱盐污水生化处理系统的菌群结构特征,识别了主要功能菌种,揭示了主要功能基因的丰度及其表达情况。结果表明:一体化间歇生物反应器(IBR)中,相对丰度占比最高的6种功能菌为Immundisolibacter cernigliae、Rugosibacter aromaticivorans、Nitrospira moscoviensis、Candidatus Nitrospira inopinata、Thauera sp.MZ1T和Nitrospira japonica,且上述功能菌的基因表达均活跃;IBR中脱氮途径以硝化-反硝化为主。A/O单元中,相对丰度占比最高的6种功能菌为Sulfuritortus calidifontis、Immundisolibacter cernigliae、Anaerolinea thermophila、Thauera sp.MZ1T、Ottowia sp.27C和Ignavibacterium album;除磷功能菌Defluviicoccus vanus虽然相对丰度较低但其表达活跃;A/O单元中硝化功能菌占比极低,脱氮功能很弱。受进水水质和运行工况影响,IBR的硝化功能显著,A/O单元的硫氧化功能显著。
Meta-omics analysis technology were employed to study the microbial community characteristics in electric desalination wastewater treatment system of two petrochemical enterprises,to identified the primary functional microbial community,and to reveal the abundance and expression of primary functional genes.In the integrated bioreactor(IBR)system,six functional bacteria with the highest relative abundance proportion are Immundisolibacter cernigliae、Rugosibacter aromaticivorans、Nitrospira moscoviensis、Candidatus Nitrospira inopinata、Thauera sp.MZ1T and Nitrospira japonica,with active gene expression.In IBR,the main denitrification pathways are nitrification and denitrification.In the A/O unit,six functional bacteria with the highest relative abundance proportion are Sulfuritatus calidifontis、Immundisolibacter cernigliae、Anaerolinea thermophila、Thauera sp.MZ1T、Ottowia sp.27C and Ignavibacterium album.The phosphorus-removal function microbial,Defluviococcus vanus,is low in relative abundance but actively expressed.In the A/O unit,the nitrifying functional microbial is low in proportion and weak in nitrification.Influenced by inlet water quality and operating conditions,the nitrification function is significant in IBR,while the sulfur oxidation function is significant in A/O unit.
