生活垃圾堆肥接种技术

Composting Technology of Municipal Solid Waste with Inoculation Agent

以复合微生物菌剂、马粪、成熟堆肥、果园土、污泥为接种剂 ,采用在线监测堆肥设备 ,通过温度传感器、出口气体O2 H2 S监测仪 ,研究堆肥过程中温度、耗氧速率、有机物分解速率、H2 S气体浓度变化 .试验结果表明 ,添加接种剂堆肥与对照组比 ,堆料能达到理想的温度 ,且高温停留时间长 ,堆肥反应速率加快及堆肥腐熟时间缩短 ,并能很好地控制出口H2 S气体浓度 .特别是以复合微生物菌剂或马粪作为接种剂 ,能明显加速堆料的腐熟进程 ,其腐熟时间分别比对照组提前 2 1 0h和 1 80h .

This paper introduced composting technology of municipal solid wastes (MSW) with inoculation agent. used complex microbial community,ordure of horse,composting, soil of garden and sewage sludge as inoculation agent, the temperature, oxygen consumption rate, organic matters degradation rate and outlet H 2S gas were detected and analyzed in composting process. The experimental results indicated that adding inoculation agent to municipal solid wastes were proper for enhancing the composting temperature, oxygen consumption rate and controlling well H 2S gas. Especially, when adding complex microbial community or ordure of horse as inoculation were effective to compose organic matter and speed up composting into humus. Therefore, adding inoculation agent to MSW greatly influence the rate of organic degradation and was useful to improve composting conditions.
