| 中文摘要: |
| 超高温好氧堆肥是高效、绿色的有机固体废弃物资源化技术，为了弥补超高温好氧堆肥在大规模工程性处理研究中的不足，通过对规模化畜禽粪便超高温好氧堆肥工程案例（处理量300 t·d-1）的分析，阐述了超高温好氧堆肥在工程应用中的原理、工艺选择、运行参数以及经济效益。槽式及条垛式规模化畜禽粪便超高温好氧堆肥的最高温度可超过80℃，20~30 d完成堆肥。堆肥结束后，含水率和有机质分别保持在44%和35%左右，EC值为2.9 mS·cm-1，水溶性有机碳和水溶性总氮的含量分别保持在3.0mg·kg-1和0.9 mg·kg-1。此外，腐熟料经过二次加工，可制备为功能性有机肥料。超高温好氧堆肥投资成本小、产品价值高，具有更高的经济效益。目前，已形成的可复制的畜禽粪便循环利用新模式，可为农林残余、生活垃圾、厨房残余等其他有机固废的规模化超高温好氧堆肥处置提供参考。 |

| Hyperthermophilic composting is an efficient and green resource recycling technology of organic solid waste. To address the lack of engineering research on large-scale hyperthermophilic composting, a case of large-scale livestock manure hyperthermophilic composting was investigated(300 t·d-1), including the principles, process selection, operating parameters, and economic benefits in the application of the hyperthermophilic composting process. The results showed that the maximum temperature for large-scale hyperthermophilic composting of livestock manure was above 80℃, and fermentation was completed in 20 to 30 days with trough and windrow composting. After composting, the moisture content and organic matter were maintained at approximately 44% and 35%, respectively, the EC value was 2.9 mS·cm-1, and the levels of water-soluble organic carbon and water-soluble total nitrogen were maintained at 3.0 mg·kg-1 and 0.9 mg·kg-1, respectively. Moreover, the decomposed material could be prepared into functional organic fertilizer after secondary processing. Hyperthermophilic composting has low investment cost, high product value, and increased economic benefits. Currently, a new model of reproducible recycling and utilization of livestock manure has been developed, which can provide a reference for the large-scale hyperthermophilic composting disposal of organic solid waste, such as agricultural and forestry residues, domestic waste, and kitchen residue. |
