摘要
依托北京市南宫堆肥厂,研究了生活垃圾的不同物理组分对高温发酵阶段的堆肥腐熟度的影响。结果表明:从EC、E4/E6、C/N、GI等指标来看,植物性垃圾对堆肥的腐熟度起主导性作用;纸类和木竹类也对堆肥的腐熟度有一定的促进作用。在8d的高温发酵阶段,以上类别的原垃圾均可以得到较充分的降解,基本达到了高温期间对腐熟度指标的要求。因此在堆肥的原料中适当增加植物性垃圾,如厨余垃圾的比例,可加快垃圾堆肥的腐熟速度。
Depended on the eomposting process in Beijing Nangong Composting Plant, the contributions of different physical components of domestic waste to compost putrescibility in the high temperature fermentation phase were analyzed. The results showed that vegetable waste played a dominant role on compost putrescibility according to the assessing index EC, Ed/E6, C/N, and GI, paper and woods also promoted the certain role in compost putrescibility. The foregoing wastes could be degraded adequately to meet the demand of putrescibility in high temperature fermentation of 8 days. Therefore, increasing the vegetable waste properly, such as kitchen waste, can speed up the compost putrefying rate.
