In this study, the main objective was to investigate the potential effect of tertiary-amine modified bentonite (TAMB) on the nitrogen transformation and the volatile fatty acids (VFAs) degradation during the chicken manure (CM) composting. Six dosages of TAMB (0%, 2%, 4%, 6%, 8% and 10%) were amended into the mixture of CM and wheat straw and then composted for 50 days. The results revealed the TAMB amendment could prolong the thermophilic phase and enhance the organic matter (OM) degradation. With the increasing dosage of TAMB, the ammonia volatilization was reduced by 15.41%–65.35%. Meanwhile, the TAMB addition had a positive effect on VFAs degradation and reducing odor unit_MAX (OU_MAX) by 17.61%–59.24%. Moreover, CH₄ was reduced by 12.15%–32.78% in TAMB applied treatments compared to control. Finally, combined with all results, it indicated that TAMB amendment could reduce VFAs, CH₄ emission and nitrogen loss to improve the compost quality.

在这项研究中，主要目的是研究叔胺改性膨润土（TAMB）对鸡粪（CM）堆肥过程中氮转化和挥发性脂肪酸（VFAs）降解的潜在影响。将六剂TAMB（0％，2％，4％，6％，8％和10％）修改为CM和麦秸的混合物，然后堆肥50天。结果表明，TAMB改性剂可以延长嗜热相并增强有机物（OM）的降解。随着TAMB剂量的增加，氨气挥发减少了15.41％–65.35％。同时，添加TAMB对VFA的降解具有积极作用，并将气味单位_MAX（OU _MAX）降低了17.61％–59.24％。此外，CH ₄与对照相比，使用TAMB的治疗减少了12.15％–32.78％。最后，结合所有结果，表明TAMB改良剂可以减少VFA，CH ₄排放和氮损失，从而改善堆肥质量。
