好氧堆肥去除畜禽粪便病原体的研究进展.

In recent years, outbreaks, such as that of African swine fever, influenza A(H1N1), avian influenza, and COVID-19, have occurred frequently. These epidemics, caused by the transmission of zoonotic pathogens such as H1N1 and avian influenza, have gradually attracted the attention of experts in the field of solid waste treatment and utilization. If livestock or poultry manure cannot be reasonably recycled, it may pose a threat to human health and ecological security because of the presence of large number of pathogens. High-temperature aerobic composting is a method of treating solid waste, during which the thermophilic stage can effectively reduce the number of pathogens. However, compost products with residual pathogens may pose safety risks after their application in soil. This review summarizes the effect of the composting process on pathogens and their consequent impacts, and discusses the possible causes and risks of residual pathogens in compost. Based on this, an optimization direction is proposed to improve the pathogen removal efficiency in composting, which would minimize the safety risks and ensure the safe and efficient use of livestock and poultry manure composting products.
