Description

Technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a low-calorific value sludge three-stage treatment process and device. Background technique [0002] In the process of sewage and wastewater treatment, a large amount of sludge will be produced. Some sludge has high organic matter content and higher calorific value after drying, which is convenient for incineration, such as sludge produced by domestic sewage treatment. Some sludges have high inorganic content, such as the sludge produced by metallurgical and electric power wastewater treatment. After drying, the calorific value is low, the energy consumption of direct incineration is high, the volume reduction is small, and the incineration product is solid slag, which is not conducive to resource utilization. [0003] For the treatment and disposal of sludge with high calorific value, mature technologies are currently available, such as the patent number "201110216120" "U...
