原始语种摘要: Abstract(#br)With the increasing use of engineering nanomaterials (ENMs) in industrial and domestic products, ENMs inevitably enter into wastewater treatment plants and remain in sewage sludge. Most of the reported studies on anaerobic digestion were focused on the impact of ENMs on different types of ENMs, methane production, key metabolism enzymes and microorganisms. Little attention was paid to the effect and mechanism of ENMs on volatile fatty acids (VFAs) accumulation during anaerobic digestion. In this work, the concentration of accumulative VFAs during anaerobic digestion with the presence of ZnO ENMs was found to be affected positively compared to the control (without ZnO ENMs). The enhanced VFAs accumulation in the presence of ZnO ENMs was contributed to slowly production and...
