堆肥作为一种常规的固体废物处理方法,在碳氮保护方面发挥着至关重要的作用,从而减少养分和能量的损失。但由于操作条件的不同,在堆肥过程中不可避免地会释放出一些含碳、氮的气体,造成碳、氮的损失。为了克服这一障碍,许多研究人员一直在尝试优化调整参数并添加一些修正(即物理修正、化学修正和微生物修正),以减少损失并加强碳和氮的保护。然而,关于碳和氮保存机制的研究是有限的。因此,本综述总结了有关物理修正的研究,化学改良剂和微生物改良剂,提出了增强碳和氮保存的潜在机制:吸附或转化,并评估了它们对缓解温室效应的贡献,为后续堆肥相关研究人员更好地改善碳和氮提供了理论基础。氮保护措施。本文还建议:评估堆肥作为一种过程对全球温室气体减排的贡献需要对堆肥进行完整的生命周期评估。目前缺乏堆肥熟料对应用场地碳氮封存能力的影响,需要更多的研究人员去探索。并评估其对减缓温室效应的贡献,为后续堆肥相关研究人员更好地改进碳氮保护措施提供理论依据。本文还建议:评估堆肥作为一种过程对全球温室气体减排的贡献需要对堆肥进行完整的生命周期评估。目前缺乏堆肥熟料对应用场地碳氮封存能力的影响,需要更多的研究人员去探索。并评估其对减缓温室效应的贡献,为后续堆肥相关研究人员更好地改进碳氮保护措施提供理论依据。本文还建议:评估堆肥作为一种过程对全球温室气体减排的贡献需要对堆肥进行完整的生命周期评估。目前缺乏堆肥熟料对应用场地碳氮封存能力的影响,需要更多的研究人员去探索。评估堆肥作为一个过程对全球温室气体减排的贡献需要对堆肥进行完整的生命周期评估。目前缺乏堆肥熟料对应用场地碳氮封存能力的影响,需要更多的研究人员去探索。评估堆肥作为一个过程对全球温室气体减排的贡献需要对堆肥进行完整的生命周期评估。目前缺乏堆肥熟料对应用场地碳氮封存能力的影响,需要更多的研究人员去探索。

Carbon and N conservation during composting: A review
Composting, as a conventional solid waste treatment method, plays an essential role in carbon and nitrogen conservation, thereby reducing the loss of nutrients and energy. However, some carbon- and nitrogen-containing gases are inevitably released during the process of composting due to the different operating conditions, resulting in carbon and nitrogen losses. To overcome this obstacle, many researchers have been trying to optimize the adjustment parameters and add some amendments (i.e., pHysical amendments, chemical amendments and microbial amendments) to reduce the losses and enhance carbon and nitrogen conservation. However, investigation regarding mechanisms for the conservation of carbon and nitrogen are limited. Therefore, this review summarizes the studies on physical amendments, chemical amendments and microbial amendments and proposes underlying mechanisms for the enhancement of carbon and nitrogen conservation: adsorption or conversion, and also evaluates their contribution to the mitigation of the greenhouse effect, providing a theoretical basis for subsequent composting-related researchers to better improve carbon and nitrogen conservation measures. This paper also suggests that: assessing the contribution of composting as a process to global greenhouse gas mitigation requires a complete life cycle evaluation of composting. The current lack of compost clinker impact on carbon and nitrogen sequestration capacity of the application site needs to be explored by more research workers.
