不同初始含水率对沼渣和秸秆混合堆肥过程的影响

为了实现沼渣的无害化处理和资源化利用,试验在沼渣污泥混合物中按一定比例加入切碎的稻草进行混合堆肥发酵,该混合物初始含水率分别设置为55%、60%、70%3个水平,对3堆堆肥在堆肥过程中进行温度、含水率、有机质等指标的测定和分析,以期找到适合高效处理堆肥过程的最佳控制因素及水平。对堆肥过程研究分析发现:3堆堆肥发酵到一定阶段时,将其含水率调节至70%后,相应指标参数发生了一系列明显变化,表明堆肥过程中适当补充水分能够加速堆肥的进程。

Effects of Different Initial Moisture Content on the Composting Process of Biogas Residue and Straw

To realize harmless treatment and resourceful utilization of biogas residue,minced straw was mixed with biogas residue at a certain proportion for fermentation.The initial water content in the mixture was set as 50%,60% and 70%;the temperature,water content and organic content of the three pile of mixture during fermentation was detected and analyzed to find a proper condition for high efficient process of piled compost.The result showed that if adjust the water content of compost to 70% during certain stag...
