摘要

Abstract

Aerobic composting technology is an important means to achieve the reduction,harmless-ness and resource utilization of organic waste,among which oxygen volume fraction is one of the core factors affecting the composting process and quality.A reasonable oxygen flow regulation strategy can maintain microbial activity,control the temperature of the pile,reduce greenhouse gas emissions,increase the degree of humification,and enhance the safety and stability of fertilizers.This article summarizes the affecting mechanisms of oxygen supply on the dynamics,metabolic pathways and de-composition activities of microbial communities.The effects of regulating oxygen concentration on im-portant composting factors such as temperature,decomposition efficiency of organic matter,and greenhouse gases,the effects of different oxygen volume fractions on compost products(including ma-turity,product safety,seed germination rate,etc.),and,the effects of raw material properties on oxy-gen diffusion and flow resistance were studied.The dynamic response relationship between the change of oxygen concentration and the physical,chemical and biological indicators of the pile dur-ing the aerobic composting process was summarized.Finally,directions and prospects for future re-search were proposed.In conclusion,this article provides a theoretical basis for promoting the up-grading of aerobic composting towards precision and low carbonization,and innovates a development path for the sustainable management of organic waste.
