摘要
污水处理过程中产生的厌氧消化气体(主要成分是CH和CO)是污水处理厂碳排放的主要来源之一。以H和CH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H或CH为基质的MBfR(H_(2)/CH_(4)-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H_(2)/CH_(4)-MBfR中微生物利用CH和CO进行自身代谢的过程,指出H_(2)/CH_(4)-MBfR实现碳减排的途径和潜力。H_(2)/CH_(4)-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。
The anaerobic digestion gas(the main components are CHand CO)produced in the sewage treatment process is one of the main sources of carbon emissions in sewage treatment plants.The rise of Hand CH-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 Hor CH(H_(2)/CH_(4)-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 CHand COfor their own metabolism in H_(2)/CH_(4)-MBfR,the pathway and potential of H_(2)/CH_(4)-MBfR to achieve carbon emission reduction were pointed out.The huge potential of H_(2)/CH_(4)-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.
