摘要

摘要本研究确定了添加β-环糊精（β-CD；0、0.15或0.25%）是否能改善绿色垃圾的两阶段堆肥。在堆肥过程中或在最终产品中测量以下参数：水分含量；体积生化和化学需氧量；腐殖物质；C/Nsolid和C/Ns可溶性；微生物数量（可培养细菌、放线菌和真菌）；酶活性（果胶酶和木聚糖酶）；微生物生物量碳和氮；有机成分的降解；磷（有效和总）、钾、钠、钙和镁的含量；以及对发芽种子的毒性。添加0.15%β-CD的GW两阶段堆肥效果最佳。仅在28天内就获得了成熟稳定的堆肥优化的两阶段堆肥天数，而不是90–270天传统堆肥通常需要几天。

Changes in Physical, Chemical, and Microbiological Properties During the Two-Stage Composting of Green Waste due to the Addition of β-cyclodextrin

Abstract This research determined whether addition of β-cyclodextrin (β-CD; 0, 0.15, or 0.25%) improved the two-stage composting of green waste (GW). The following parameters were measured during composting or in the final product: moisture content; volume; biochemical and chemical oxygen demand; humic substances; C/Nsolid and C/Nsoluble; microbial numbers (culturable bacteria, actinomycetes, and fungi); enzyme activities (pectinase and xylanase); microbial biomass carbon and nitrogen; degradation of organic components; contents of phosphorus (available and total), potassium, sodium, calcium, and magnesium; and toxicity to germinating seeds. The two-stage composting of GW was optimal with the addition of 0.15% β-CD. A mature and stable compost was obtained in only 28 days with the optimized two-stage composting rather than in the 90–270 days typically required for traditional composting.
