摘要
随着城市化和人口增长,全球废水处理面临巨大问题。膜曝气生物膜反应器(Membrane Aeration Biofilm Reactor,MABR)作为一种新兴的废水处理技术,展现出显著的处理优势。MABR的无泡曝气理论氧气传输效率可达100%,传氧速率(Oxygen Transfer Rate,OTR)可达8~15 g O_(2)/m^(2)·d,能耗仅为传统系统的30%~50%。在应用方面,MABR在处理市政污水时,总氮(Total Nitrogen,TN)去除率可达65%~91%,化学需氧量(Chemical Oxygen Demand,COD)去除率可达70%~96%;处理高盐废水时,TN去除率超99%。MABR在氧气传输效率、能耗降低、污染物去除率等方面有着显著提升,凸显了其在废水处理领域的巨大潜力。
With urbanization and population growth,wastewater treatment faces huge challenges globally.MABR,an emerging technology,offers significant advantages.Its bubble-free aeration can reach 100%oxygen transfer efficiency,with an OTR of 8~15 g O_(2)/m^(2)·d and energy use at 30%~50%of traditional systems.MABR removes 65%~91%TN and 70%~96%COD in municipal wastewater,and over 99%TN in high-salt wastewater.MABR has a significant improvement in oxygen transmission efficiency,energy consumption reduction,and pollutant removal rate.These improvements highlight MABR's potential in wastewater treatment.
