英文摘要	The effects of biochar on temperature related performance and thermal loss during swine manure composting, when different mechanical turning frequencies were adopted, were investigated. Monitoring results showed that biochar addition significantly increased accumulated temperature and prolonged duration of thermophilic phase. More importantly, biochar addition remarkably reduced total thermal loss, which was a consensus between decreased heat exchange and incremental water vaporization heat, when there was one turning event. From heat output point of view, biochar decreased heat exchange and incremental water vaporization heat when one and two turning happened. In detail, biochar decreased the proportion of heat exchange from 66.2% to 61.6% and 67.2% to 62.7% respectively, and increased water vaporization heat from 22.1% to 32.9%, 17.3% to 23.9% respectively. Finally, biochar showed a potential to mitigate thermal loss caused by turning during swine manure composting.
