[目的]探究温度和物料配比对城市园林绿化废物与鸡粪水浴法好氧堆肥的影响,为大规模好氧堆肥提供技术指导与理论基础。[方法]以恒温水浴锅、空气泵、气体转子流量计、温度计、发酵瓶与洗气瓶为材料,构建水浴法温控好氧堆肥装置,开展城市园林绿化废物与鸡粪质量比分别为2: 3,2: 1,3: 1,5: 1(分别命名A,B,C,D组)水浴法堆肥试验。[结果]城市园林绿化废物与鸡粪发酵堆肥微生物代谢活性最佳温度在50~55 ℃之间,当温度≥55 ℃,微生物对有机物的降解受到明显抑制。从温度变化看,A-D组堆肥均经历了升温期、高温期、降温期和中温期。A-D组堆肥氮素损失率分别为47. 11%±0.55%,63.82%± 1.05%,53. 43%±0....

[Objective] The effects of temperature and material ratio on urban landscaping waste and chicken manure water bath aerobic composting were studied in order to provide technical guidance and theoretical basis for large-scale aerobic composting. [Methods] A water bath temperature-controlled aerobic composting device was constructed with water bath incubator, air pump, gas rotameter, thermometer, fermentation bottle and a gas bottle. Water bath composting with different ratios of urban gardening waste to chicken manure of 2:3,2:1,3:1,and 5: 1 (nam...
