Bio-drying of Dewatered Sludge and Changes of Calorific Value

  • 摘要: 探讨了物料配比、翻堆方式和通风量对脱水污泥生物干化的影响,分析了污泥生物干化前后热值的变化情况.结果表明,当污泥与园林垃圾的配比为5:2时,温度峰值最高,达54.6℃,物料含水率下降了11.22%,且VS去除率最高;与不翻堆的试验相比,翻堆试验的最终含水率为45.98%,比不翻堆的低2.54%;当通风量为0.5m3/h时,有利于堆体温度的上升和强化干化效果.采用最佳的生物干化条件对污泥进行预干化处理后,堆体的含水率从60.45%降至42.57%;干化后物料的低位热值达到9763.3kJ/kg,有良好的热值资源化前景.
