摘要:

污水处理过程中产生的厌氧消化气体(主要成分是CH4和CO2)是污水处理厂碳排放的主要来源之一。以H2和CH4为基质的膜生物膜反应器(MBfR)技术的兴起,为氧化性污染物的生物还原和污水处理厂的碳减排提供了一种很有前景的方案。介绍了以H2或CH4为基质的MBfR(H2/CH4-MBfR)的运行原理、优缺点,对MBfR在去除氧化性污染物方面的研究情况进行了总结、比较和评价。通过解析H2/CH4-MBfR中微生物利用CH4和CO2进行自身代谢的过程,指出H2/CH4-MBfR实现碳减排的途径和潜力。H2/CH4-MBfR在碳减排方面表现出的巨大潜力为实现“碳达峰”和“碳中和”提供了新方向,使得污水处理厂有望同步实现污染物去除和碳减排。

Abstract:

The anaerobic digestion gas (the main components are CH4 and CO2) produced in the sewage treatment process is one of the main sources of carbon emissions in sewage treatment plants. The rise of H2 and CH4-based membrane biofilm reactor(MBfR) technology provides a promising solution for biological reduction of oxidative pollutants and carbon emission reduction in wastewater treatment plants. The operation principle,advantages and disadvantages of MBfR based on H2 or CH4(H2/CH4-MBfR) were introduced,and the research status of MBfR in removing oxidative pollutants were summarized,compared and evaluated. By analyzing the process of microbial use of CH4 and CO2 for their own metabolism in H2/CH4-MBfR,the pathway and potential of H2/CH4-MBfR to achieve carbon emission reduction were pointed out. The huge potential of H2/CH4-MBfR in carbon emission reduction provided a new direction for the realization of “carbon peaking” and “carbon neutralization”,so that sewage treatment plants were expected to simultaneously achieve pollutant removal and carbon emission reduction.

Key words: MBfR, H2, CH4, oxidizing pollutants, methane oxidation, carbon reduction
