生物干化技术是在好氧发酵的基础上，利用可降解有机物分解代谢作用时产生的生物热量，通过通风、翻堆等过程控制手段，促进物料中水分快速散失，降低含水率的干化工艺。污泥生物干化过程受物料性质、温度、含水率、调理剂、通风、机械翻堆等因素的影响。与其他污泥干化技术相比，生物干化技术更经济、节能、环保且具有良好的应用和发展推广前景。%On the basis of aerobic fermentation, the biological dried technique uses degradable organic matters decom-position and produces the bio-quantity of heat, it promotes the water quick dissipation of materials and reduces the containing water rate through aeration and turning over process. In comparison with other sludge dried technique, the biological dried technique is provided with economy, energy saving, environmental protection and a favorable prospect in application, develop-ment and popularization.
