Drying sewage sludge by indirect heating by extraction steam from turbine is the best technology for power generation by sludgeincineration because the total cost of sludge disposal is the lowest.
采用汽轮机抽汽间接加热方法干化污泥，污泥处理的直接成本最低，是最佳的污泥焚烧发电技术。

While its popularization and application is limited by the emission of heavy metals, dioxin, NOx, SOx, etc. Therefore, it is necessary to study the secondly pollution in sludgeincineration process.
Through the incineration experiment of dried sludge in fluidized bed incinerator, the operation experience and pollutant emission characteristics of sludge fluidized bed incineration were grasped.
