Research on the technical and economic assessment index system for sludge drying and incineration
Drying and incineration can achieve intensive and efficient reduction,stabilization,and hazard-free treatment of sewage sludge,and is currently one of the mainstream technologies for sludge treatment and disposal.The process of the drying and incineration is relatively complex,with numerous equipment and instruments,making it difficult to objectively evaluate the engineer-ing design and operation situation.Based on the characteristics and evaluation needs of the main-stream process of sludge drying and incineration in China,namely"Indirect drying+Fluidized bed incineration",a technical and economic assessment index system suitable for project state charac-terization,problem identification,optimization direction identification,and optimization space esti-mation has been proposed.Taking a certain sludge drying and incineration engineering as an exam-ple,a brief analysis of the index system used for its operation state assessment at different times has been conducted.
