摘要
污泥的厌氧消化技术能够有效实现污泥的减量化、无害化与资源化,在当今许多国家得到了广泛的应用。为了提高厌氧消化过程的效率,各种化学、物理以及生物技术被用于厌氧消化的预处理。介绍了碱解处理、热处理、超声波处理、微波处理的基本原理、特点及应用前景,并对近几年研究者们所关注的一些联合预处理技术做了介绍。
Aanaerobie digestion is a common method for sludge stabilization to achieve sludge reduction, harmlessness and resource reuse. Due to demands for higher efficiency process, various chemical, physical and biological methods have been used to improve solubilization and digestibility of anaerobic digestion. This study aimed to discuss the basic principles, characteristics and future application of alkaline pretreatment, thermal pretreatment, ultrasound pretreatment and microwave pretreatment. And some combined pretreatments which were concerned by people these years were presented.
