Compost can realize the recycling of organic waste. However, it also emits NH and greenhouse gases (GHGs) to the environment, which leads to nitrogen loss and global warming. Adding additives to compost can alleviate the emission of NH and GHGs. The mechanism of nitrogen transformation and GHGs emission was studied with deer manure and corn straw as compost substrate, and biochar and zeolite as additives. The results showed that the addition of zeolite in compost is good for prolonging high-temperature composting time. The addition of zeolite reduced the transformation of NH-N and the NO emission. The addition of zeolite is beneficial to reduce nitrogen loss during composting. CH emission is an important factor affecting the global warming potential of composting, and it is necessary to improve ventilation conditions in order to alleviate anaerobic. This study is of great significance to reduce nitrogen loss and improve composting effect.
堆肥可以实现有机废物的循环利用。然而，它也会向环境中排放氨气和温室气体（GHGs），导致氮素损失和全球变暖。在堆肥中添加添加剂可以缓解氨气和 GHGs 的排放。本研究以鹿粪和玉米秸秆为堆肥基质，以生物炭和沸石为添加剂，研究了氮素转化和 GHGs 排放的机理。结果表明，沸石的添加有利于延长高温堆肥时间。沸石的添加降低了 NH-N 的转化和 NO 的排放。沸石的添加有利于减少堆肥过程中的氮素损失。CH 排放是影响堆肥全球变暖潜势的重要因素，有必要改善通风条件以缓解厌氧。本研究对于减少氮素损失和提高堆肥效果具有重要意义。
