摘　　要：目前,厨余垃圾、园林废弃物、农畜废弃物、污水污泥等有机废弃物的无规则排放导致环境污染日益严重,寻找一种有机废弃物的绿色处理方法已经成为研究热点。厌氧消化作为处理有机废弃物常用的手段已被广泛使用。然而,有机废弃物中的微塑料胁迫会使厌氧消化效率降低,从而降低废弃物利用率。分析导电材料缓解微塑料对有机废弃物中厌氧消化的抑制以及群体感应和种间电子转移对功能微生物的影响,探讨导电材料提高含有微塑料的有机废弃物厌氧消化效率的机制,为微塑料污染物所造成的有机废弃物处理提供解决方案。At present,the environmental pollution caused by the irregular discharge of organic waste(mainly kitchen waste,garden waste,agricultural and livestock waste,sewage sludge,etc.)has become increasingly serious.Therefore,finding a green method to deal with organic waste has become a research hotspot.Anaerobic digestion has been widely used as one of the commonly used methods for the treatment of organic waste.However,under the stress of microplastics in organic wastes,the efficiency of anaerobic digestion is often decreased,thus reducing the utilization rate of organic waste.The effects of conductive materials on alleviating the inhibition of microplastics on anaerobic digestion of organic wastes and the effects of quorum sensing and interspecies electron transfer on functional microorganisms were analyzed.The mechanism of conductive materials to improve the anaerobic digestion efficiency of organic wastes containing microplastics was discussed,which provided a solution for the treatment of organic wastes caused by microplastic pollutants.
