摘要
在实验室条件下进行了仓式好氧堆肥实验,研究了城市有机固体废物堆肥物料种类、温度、含水率、固体颗粒粒度、碳氮比等因素对堆肥过程中有机物降解的影响.实验结果表明最佳堆肥实验条件为:温度40～50℃,含水率50%,粒径30mm,C/N质量比30∶1.实验结果显示为了保证仓式好氧堆肥反应的顺利进行,上述几个因素应当被严格地控制在适当范围内.另外,通过正交实验对各影响因素进行了比较,发现在研究的4个主要影响因素中含水率的影响作用最大,C/N质量比其次,温度和物料的粒径所起的影响作用最小.
The main factors influencing the organic solid waste biodegradation in aerobic vessel compost system, which included the kinds of composting materials, temperature, moisture content, particle size and C/N ratio in aerobic composting ,were investigated by doing a set of bench-scale laboratory experiments. The study showed that the optimum process conditions were 40～50 ℃, 50% moisture content 30 mm particle size and the C/N ratio of 30∶1. The experiment results showed these factors should be strictly controlled in a proper range to ensure composting reactions. The factors were compared through orthogonal experiments. The results showed that moisture content was the most significant factor in TOC biodegradation, C/N ratio the next, and the temperature and particle size the least.
