摘要
腐熟度参数及其指标是评价堆肥过程及堆肥产品质量的重要尺度。腐熟度指标可分为三类:物理学指标、化学指标和生物学指标。目前还没有一种公认的堆肥腐熟度指标。通过系统分析现有堆肥腐熟度指标的特点及局限,讨论了建立垃圾堆肥腐熟度综合判断的必要性和可行性,提出了以C/N、比耗氧速率(SOUR)、NH4+-N为指标建立堆肥腐熟度综合评价方法。
Evaluation of the compost maturity is important for both composting and compost. The parameters for compost maturity are grouped into three types: physical, chemical and biological indices. There is no unanimous parameter to evaluate compost maturity till now. In this paper, the characteristics and shortcomings of existing parameters are analyzed. The necessity and feasibility to build a comprehensive assessment of compost maturity is discussed and the C/N, NH4+-N, SOUR are suggested indices for assessment.
