摘要： A method and system for treating biosolid material having pathogens, the method including: introducing dried biosolid material into a pathogen treatment vessel; monitoring an actual temperature of the dried biosolid material in the treatment vessel; determining a desired residence time of the biosolid material in the treatment vessel; determining a desired minimum temperature of the dried biosolid material in the treatment vessel, wherein the minimum temperature is based on the desired determined residence time of the biosolid material in the treatment vessel; passing the dried biosolid material through the treatment vessel such that the actual residence time of the biosolid material in the treatment vessel is at least as long as the determined residence time; applying heat from a hot fluid to the dried biosolid material in the treatment vessel, if the actual temperature of the biosolid material is lower than the minimum temperature, and reducing pathogens in the biosolid material by maintaining the biosolid material in the treatment vessel for at least the determined residence time while the actual temperature is at least as hot as the minimum temperature.
