摘要
有机固体废弃物堆肥的腐熟度指标是评价堆肥稳定及安全农用的重要参数,通过综述堆肥的物理、化学、生物学指标,提出评价堆肥的腐熟度时,物理指标一般作为辅助指标,化学指标中T值≤0 6、水溶性C/总有机N≤0 70可以稳定应用,核磁共振和红外光谱分析可以精细地评价腐熟后堆肥产品中各组分,发芽率指标可作为堆肥产品安全稳定的生物指标。在应用时要与BOD、CEC、腐殖化参数等多方面结合来评价堆肥的腐熟程度。
The maturity indexes of organic solid waste compost are important parameters evaluating stability and safe guarantee for agricultural utilization. The maturity physical indexes, chemical indexes and biological indexes are reviewed in the paper. Physical indexes can be used as subsidiary parameters, the amount of T ≤0.6 and the ratio of WSC to total organic nitrogen ≤0.70 can be used as chemical parameters, ^(13)C-NMR and FTIR can be used to evaluate ingredients of maturity compost. Seed germination index, as biological parameter, was recommended to be a safe and stabile parameter of maturity compost. BOD, CEC and humification indexes can be combined while evaluating maturity.
