Aerobic composting has been used for a long time for bioconversion of manure wastes, however, its application has been limited due to slow transition of organic matters and influence of heavy metals and antibiotics residues. Compost with lime addition can speed up the composting process, while its effects on the evolution of organic matters, heavy metals and antibiotics need to be further investigated. In this research, the effects of lime amendment on organic substances changes was assessed by the spectroscopic characteristics. Besides, chlortetracycline (CTC) removal and Cu, Zn chemical speciation transformation were also evaluated. Results showed that the humic acid-like substances region of fluorescence regional integration (FRI-EEM) increased from 20.5% to 40.9% and 20.6% to 32.6%, respectively, in lime addition treatment and control after 15 days of composting, indicating that the addition of lime remarkably improved the transition of organic matter and accelerated the maturity process. Besides, 94.04% of CTC in the manure was removed when lime was added, higher than 86.10% in the control group. The transformation of zinc from exchangeable and reducible into oxidizable and residual fractions was improved while the transformation of copper was affected slightly. Therefore, lime is a suitable amendment material for manure composting, which can accelerate the transition of organic matters due to the regulation of composting pH, as well as eliminate harmful CTC and bioavailable heavy metal, thus promoting the further utilizing of organic substance.

好氧堆肥用于粪便废物的生物转化已经很长时间了，但是由于有机物的缓慢转化以及重金属和抗生素残留的影响，其应用受到了限制。添加石灰的堆肥可以加快堆肥过程，而其对有机物，重金属和抗生素的演变的影响还需要进一步研究。在这项研究中，通过光谱特性评估了石灰改良剂对有机物变化的影响。此外，还评估了金霉素的去除以及铜，锌化学形态的转化。结果表明，荧光区域整合（FRI-EEM）的腐殖酸样物质区域分别从20.5％增至40.9％和20.6％增至32.6％。在堆肥15天后进行石灰添加处理和控制，表明添加石灰显着改善了有机物的转化并加速了成熟过程。此外，加入石灰后，粪便中的四氯化碳含量去除了94.04％，高于对照组的86.10％。锌从可交换和可还原到可氧化和残留部分的转化得到改善，而铜的转化受到轻微影响。因此，石灰是用于肥料堆肥的合适的改良材料，由于堆肥pH值的调节，它可以加速有机物的转化，并消除有害的四氯化碳和可生物利用的重金属，从而促进有机物的进一步利用。表明添加石灰显着改善了有机物的转化并加速了成熟过程。此外，加入石灰后，粪便中的四氯化碳含量去除了94.04％，高于对照组的86.10％。锌从可交换和可还原到可氧化和残留部分的转化得到改善，而铜的转化受到轻微影响。因此，石灰是用于肥料堆肥的合适的改良材料，由于堆肥pH值的调节，它可以加速有机物的转化，并消除有害的四氯化碳和可生物利用的重金属，从而促进有机物的进一步利用。表明添加石灰显着改善了有机物的转化并加速了成熟过程。此外，加入石灰后，粪便中的四氯化碳含量去除了94.04％，高于对照组的86.10％。锌从可交换和可还原到可氧化和残留部分的转化得到改善，而铜的转化受到轻微影响。因此，石灰是用于肥料堆肥的合适的改良材料，由于堆肥pH值的调节，它可以加速有机物的转化，并消除有害的四氯化碳和可生物利用的重金属，从而促进有机物的进一步利用。锌从可交换和可还原到可氧化和残留部分的转化得到改善，而铜的转化受到轻微影响。因此，石灰是用于肥料堆肥的合适的改良材料，由于堆肥pH值的调节，它可以加速有机物的转化，并消除有害的四氯化碳和可生物利用的重金属，从而促进有机物的进一步利用。锌从可交换和可还原到可氧化和残留部分的转化得到改善，而铜的转化受到轻微影响。因此，石灰是用于肥料堆肥的合适的改良材料，由于堆肥pH值的调节，它可以加速有机物的转化，并消除有害的四氯化碳和可生物利用的重金属，从而促进有机物的进一步利用。
