N-甲基二乙醇胺的生物电化学处理技术
Bioelectrochemical treatment technology of N-methyldiethanolamine
摘要
Abstract
This study focused on N-methyldiethanolamine(MDEA)in petrochemical wastewater and evaluated the enhanced treatment efficiency of bioelectrochemical technology compared to conventional biological treatment.By analyzing the succession patterns of microbial community structures in the system,the degradation mechanism of MDEA in bioelectrochemical systems was elucidated.Experimental results demonstrate that under the conditions where the COD in influent is 384.00-410.00 mg/L,and the TKN in influent is 29.61-38.94 mg/L,the bioelectrochemical technology achieves a 93.38%COD removal rate and 92.43%TKN removal rate,while simultaneously effectively reducing wastewater toxicity.The electric field significantly alters microbial community composition in the treatment system.This transformation not only inducesthe development of electroactive microorganisms but also notably enriches pollutant-degrading microbial populations.Dominant genera in the bioelectrochemical system include Methyloversatilis,Mycobacterium,and Rhodanobacter.Under electric field stimulation,the system enhances MDEA treatment efficiency primarily by increasing the abundance of Proteobacteria,Actinobacteriota,Planctomycetota,Chloroflexi,and Desulfobacterota.关键词
