不完全厌氧-好氧堆肥处理有机垃圾技术研究

Technology of Anaerobic hydrolytic-Aerobic Composting for Organic Waste Treatment

为对比不完全厌氧-好氧堆肥与好氧堆肥的过程和效果,探究微生物菌剂对堆肥的影响,分别在有机垃圾中添加猪粪、麦糠和微生物菌剂,对各处理在堆肥过程中温度、p H、含水率、全碳、全氮和C/N的变化进行了分析和研究。结果表明,不完全厌氧-好氧堆肥在堆肥前期保温、升温效果好,水分蒸发慢,p H下降明显,与好氧堆肥相比,具有有机质分解彻底、氮素流失少等特点。此外,微生物菌剂可在一定程度上提高堆肥处理效果。

The process and effects of anaerobic hydrolytic - aerobic composting and aerobic composting were compared and the influence of microbial agents on the composting process was investigated. The pig manure, wheat bran and microbial a- gents were added to the organic waste respectively. Temperature, pH, water content, total carbon, total nitrogen and C/N changes of different composts were analyzed and researched. The results indicated that anaerobic hydrolytic-aerobic composting in the early stage had a better effect of heat preservation and warming, slow evaporation of water, downtrend of pH. Compared with aerobic composting, organic matter decomposition was thorough and nitrogen loss was less. In addition, the effects of corn- posting treatment were enhanced by microbial agents.
