| 摘 要： | 根据常见物料的自身特征及国内外评价堆肥腐熟度的相关标准，提出以堆肥高温期持续时间、C／N降解速率、NH3-N／NO3-N、种子发芽指数、NH3-N降解速率5个指标作为堆肥腐熟度的判别指标，并基于模糊数学方法建立腐熟程度的综合判别模型，然后利用该模型验证了分别以污水污泥和生活垃圾为物料的3种堆肥样品的腐熟度。结果表明，利用这5个指标，通过综合判别模型可以作为污泥（C／N初≥C／N终）、生活垃圾高温好氧堆肥腐熟程度通用的判别方法．判别结果合理且较符合实际。

| Abstract: | According to characteristics of common material and relative standards to evaluate compost maturity both in China and abroad, duration time of high temperature, C/N degradation rate, NH3-N/NO3-N, seed germination index, NH3-N degradation rate were taken as indexes of compost maturity. The integrated judgment model was built based on fuzzy mathematics method. And the model was used to assess the degree of maturity of three kinds of composts derived from sewage sludge and domestic waste, respectively. The results demonstrated that using the five indexes of compost maturity through the integrated judgment model could obtain reasonable and more practical results to reflect the degree of maturity of composts from sewage sludge （C/N初≥C/N终） and domestic waste in thermophilic aerobic composting. |
