摘　　要：以亚/超临界水处理工艺的原理和相关理论依据为基础,研究该工艺处理脱水污泥的农业利用可行性。结果表明,亚临界水比超临界水更适合污泥的资源化处置,技术和安全性在理论上可行,但推行该技术仍需要通过开展后续的深入研究以及获得示范性项目的连续运行效果以提供理论和实践支持。Based on the principal and related theory of subcritical/supercritical water treatment technological processes, feasibility of sewage sludge for agricultural utilization after treatment by subcritical/supercritical water technological processes was studied. Re- suits show that subcritical water condition is much more suitable than supercritical one for sludge reutilization. The technological pro- cess is feasible in theoretically. Furthermore, much deeper research and pilot projects are necessary as basic of theory and experi- ence which to support promoting the technological processes.
