- Abstract:
- Thermal hydrolysis strengthens the reduction, stabilization, harmlessness and resource utilization of anaerobic digestion of sludge, which has attracted the attention of science and industry for many years. With the development of the thermal hydrolysis and anaerobic digestion technology, it is particularly important to comprehensively analyze the problems existing in the industrialization of thermal hydrolysis and anaerobic digestion. Based on the technical characteristics of thermal hydrolysis and anaerobic digestion of sludge, combined with actual engineering cases and data, it summarizes and analyzes the process flow, technical drawbacks, and major operation problems existing in the application of thermal hydrolysis and anaerobic digestion, and proposes related recommendations. In order to take advantages of the thermal hydrolysis and anaerobic digestion technology and solve the existing problems, these factors and the layout of sewage treatment plants should be considered in planning and design. The thermal hydrolysis and anaerobic digestion technology of sludge needs to be flexible and applicable to reflect its advanced nature of “pollution control” and “resource recovery”.
