复合微生物菌剂强化堆肥技术研究

采用复合微生物菌剂对生活垃圾的接种堆肥技术进行了实验研究。通过测定堆肥过程中反应器出口O2、CO2与H2S气体浓度及对堆肥样品扫描电镜照片分析，比较了3个接种组与1个对照组中堆料中微生物总数变化、种群结构演替及堆肥腐熟速度。试验结果表明，在原料成分为：生活垃圾／成熟堆肥=80／20，有机物约为60％，初始含水率为55％，初始C／N-30时，对于不同接种量的复合微生物接种系统堆料中分别接种0．2％、0．3％、0．5％(质量百分含量)，与加入0．3％灭活菌的对照组进行对比实验，接种复合微生物菌剂堆肥系统不仅微生物总数高于对照组，而且其种群结构合理，能明显提高堆肥效率，有效控制臭气的产生，提高堆肥腐熟度。

Study on inoculation technology of complex microbial community for composting enhancement

The effect of complex microbial community in composting processes of municipal solid waste (MSW) were examined through inspecting outlet gas(O\-2, CO\-2, H\-2S) and scanning samples with scanning electronic microscopy. The total number of microorganisms as well as their structures were also examined. Composting was performed under such conditions: the ratio of MSW/composting is 80/20; Organic matter is 60%; original moisture is 55%; original ratio of C/N is 30; the rates of adding complex microbial community to treatment 1, tretment 2 and treatment 3 were 0.2%, 0.3%, 0.5%, respectively, and the control experiment was conducted with 0.3% inactive complex microbial community. The results indicated that adding complex microbial community in a municipal solid waste composting process was effective for increasing composting rate, controlling H\-2S gas emission and speeding up the humus producing.
