强化废水厌氧消化过程的导电材料及其特性影响
Conductive materials for enhanced anaerobic digestion of wastewater and influence of their properties
摘要
Abstract
Anaerobic digestion of wastewater is a biological treatment process in which microorganisms degrade organic substrates in an anaerobic environment and produce biogas,which has great potential to reduce energy dependence.However,due to the low methane yield,easy acidification,slow microbial enrichment,and unstable reactor operation,the traditional anaerobic technology has caused increasing energy consumption and treatment costs.Conductive materials can stimulate the interspecific electron transfer between syntrophic bacteria and methanogenic archaea,thereby improving the efficiency of methanogenesis,and are widely used in the field of wastewater anaerobic treatment.On the basis of sorting out the enhanced efficiency of carbon-based,metal-based and other conductive materials mediated anaerobic digestion,the advantages of composite synergistic effect in efficient biodegradation and high stability of operation were emphatically introduced.The effects of different physical and chemical properties of materials on enhanced anaerobic digestion performance were discussed from the aspects of particle size,conductivity and surface characteristics,and the research prospect of enhanced anaerobic biodegradation of wastewater by conductive materials was prospected.关键词
