摘　　要：以快速降低含水率、提高生活垃圾热值为研究目的,利用工程用堆肥料仓作为试验平台,通过控制进仓物料、堆高、通风量、翻堆等反应条件进行生物干化过程,研究有机物的降解情况以及含水率与热值的变化规律。试验结果表明,以原生垃圾为进料,堆高1.5 m,通风量0.32 m3/(min.m3),反应进行到第4天进行翻堆,生活垃圾中水分去除率达到16%,热值可提高到5 376 kJ/kg。The test aims to quickly reduce water content and raise caloric value,in which the aeration composting depot is used as a platform,to conduct bio-drying process by controlling materiel,turning,height,air-flow rate and so on,researches on the degradation of organic substances and changes of water content and caloric value.The results show that if the materiel is the initial waste,the removal efficiency of water content can reach 16% and the caloric value can be raised to 5 376 kJ/kg when the height,air-flow rate and turning time remains 1.5 m,0.32 m3/(min·m3)and the forth day respectively.
