Application Progress of Membrane-Aerated Biofilm Reactor in Aquaculture Wastewater Treatment
摘要
Abstract
[Objective]Aquaculture wastewater is characterized by high concentrations of ammonia nitrogen and organic pollutants,as well as the presence of antibiotics.It requires treatment to mitigate pollution to receiving water bodies.The membrane-aerated biofilm reactor(MABR)is a novel biological reaction system that integrates aeration membranes with biofilms.It enables bubble-free aeration and simultaneous nitrogen and carbon removal,thus exhibiting significant application potential in aquaculture wastewater treatment.[Methods]This paper reviews the performance of single-stage/multi-stage MABR systems and their coupled processes in conventional pollutant removal,nitrous oxide emission reduction,and antibiotic degradation.Mechanisms including MABR operational principles,nitrogen migration pathways,and microbial metabolic degradation were analyzed using method such as electron transfer analysis and gene expression detection.Additionally,the effects of antibiotics on the nitrogen removal performance of MABRs were summarized and generalized.[Results]Through the analysis,this paper summarizes the optimized process parameters and key influencing factors,providing theoretical support for the efficient operation of MABR.Given the dual impacts of antibiotics on aquatic environments and MABR operation,the response mechanisms of MABR to antibiotic shock were summarized in two aspects:biofilm barrier protection and antibiotic resistance gene regulation.These findings offer a theoretical basis for in-depth exploration of antibiotic degradation mechanisms.[Conclusion]For future research on MABR application in aquaculture wastewater treatment,focus should be placed on the performance optimization of aeration membranes,the synergistic enhancement mechanisms of coupled processes,and the regulatory strategies of microbial communities in response to antibiotic resistance genes.关键词
