摘　　要：污泥单独焚烧工艺因其减量化、无害化和稳定化最为彻底的优点而逐渐被接受和推广。基于污泥的化学元素及物化特性分析,从机理角度解析了污泥独立焚烧工艺的各项子系统,包括污泥脱水及干化预处理、干污泥储存、焚烧系统及焚烧辅助系统等,提出了各工艺子系统设计及运行时的注意事项。污泥焚烧技术具有独特的优点,体现了能源的循环利用和可持续的发展理念,其应用将越来越广泛。The mono-incineration technology has been gradually accepted and popularized because of its advantages including reduction, hamilessness and stabilization of sludge processing. Based on analysis of chemical elements and physicochemical properties of sludge, the subsystems of the monoincineration process were analyzed from the mechanism perspective, including sludge dewatering and drying pretreatment, dry sludge storage, incineration system and incineration auxiliary system. At the same time, the attention items for design and operation of each subsystem were put forward. With the unique advantages, sludge incineration technology had the concept of sustainable development and could realize the energy cycling. Its application would be more and more extensive.
