| 中文摘要 |
| 利用高效复合微生物菌群对生活垃圾和污泥混合堆肥,通过测定堆肥过程中总菌数、温度、有机物、C/N比等,较系统地研究了高效复合微生物菌群在生活垃圾、污泥混合堆肥系统中的作用.试验证明:在生活垃圾和污泥共堆肥系统中,调节堆料比为厨房垃圾:污泥:粉煤灰土:成熟堆肥污泥:干草=41.6:27.8:13.8:11.1:5.5,有机物约为60%,总氮14%,全磷0.69%,全钾1.25%;初始含水率为58.5%,初始C/N比=30i供气量控制在0.8L/min·kg挥发性有机物,处理1、处理2、处理3堆料中分别接种2%、3%、5%(质量分数)的高效复合微生物菌群,与加入3%灭活菌的对照组进行对比实验.对照组、处理1、处理2和处理3堆肥系统垃圾腐熟时间分别为30d、24d、18d和12d;说明高效复合微生物菌群可以加速生活垃圾和污泥的降解,保证堆肥过程的顺利进行.处理3与对照组相比,堆腐时间缩短了18d,同时成品堆肥中含有大量具有生物活性的微生物,是一种良好的生物活性有机肥料.

| 英文摘要 |
| The effects of high effective complex microbial community (MECMC) in a combination composting process of municipal solid waste (MSW) and sludge were examined through inspecting biomass,temperature,organic matter,the carbon,nitrogen ration (C/N).Composting was performed under such conditions:The ratio of MSW:sewage:sawdust:composting of 45∶25∶15∶15 (W/W) and organic matter of 60%,total N of 1.4%,total P of 0.69%,total K of 1 25%, original moisture of 58.5%,original ratio of C/N of 30,aration flow of 0.8L/min·kg(volatile organic matter).The rates of adding HECMC to treatment 1,treatment 2 and treatment 3 were 2%,3%,5% respectively.Control experiment added 3% inactive HECMC.The day of MSW and sludge mature in control experiment,treatment1,treatment 2 and treatment 3 were 30,24,18 and 12,respectivly.This indicated HECMC were effective to compose organic matter and speedup composting change into humus.There are many active bacteria in composting which are favorable for soil. |
