【摘要】 为探讨热预处理(Thermal Pretreatment, TP)对鸡粪堆肥发酵过程和堆肥品质的影响，试验通过自制的加热设备将鸡粪与稻壳的混料预处理后进行好氧堆肥，此为试验组(TP组),原料直接好氧堆肥为对照组(CK组),对比两组堆肥过程中理化指标和腐熟度指标的变化情况，以及堆肥结束时各组之间堆肥质量的差异性。结果表明，TP组堆肥温度达到50℃的时间比CK组提前了5 d,高温(>55℃)维持时间比CK组多2 d,高温峰值(65.1℃)比CK组高6.8℃。堆肥结束时，TP组总有机碳下降率、全氮上升率、腐殖酸上升率和种子发芽指数值都有极显著的提高。综上，热预处理能使发酵过程中有机碳的分解效率更高，防止氮损失，并显著提高了最终堆肥产品的腐熟度。更多还原

【Abstract】 To explore the effects of thermal pretreatment on the process and quality of chicken manure composting, an experiment was conducted using a self-made heating device. The pretreated chicken manure was mixed with rice husks for aerobic composting, desingated as the experimental group(TP group), while the raw materials underwent direct aerobic composting was designated as the control group(CK group). The changes of physical and chemical indicators and maturity indicators in the two groups during the composting process, as well as the differences in compost quality between the groups at the end of composting were compared. The results showed that the TP group reached a temperature of 50 ℃ five days earlier than the CK group, maintained high temperatures(above 55 ℃) for two additional days, and achieved a peak temperature of 65.1 ℃, which was 6.8 ℃ higher than that of the CK group. At the end of the composting process, the TP group exhibited significantly greater reduction in total organic carbon(TOC), increase in total nitrogen(TN), increase in humic acid(HA), and higher germination index(GI) values. These results suggest that thermal pretreatment enhances the decomposition efficiency of organic carbon during fermentation, prevents nitrogen loss, and significantly improves the maturity of the final compost product.更多还原
