Development and Trend of Sludge Incineration Technology

With the continuous improvement of China's sewage treatment capacity, the amount of sludge has increased sharply, posing a severe challenge to environmental safety and disposal costs. In this paper, the development and trend of sludge incineration technology are analyzed, with emphasis on the characteristics, effects and practical applications of this technology, including the progress of equipment optimization, process innovation and pollutant emission control. At the same time, this paper emphasizes the bottleneck problems faced by the technology, and proposes the rotary kiln incineration technology as an efficient and environmentally friendly sludge treatment means, strengthening the pretreatment and drying process can reduce the water content of the sludge, thereby reducing the exhaust gas. By combing the current technical status and looking forward to the future trend, this paper provides theoretical basis and practical guidance for improving efficiency, reducing costs, realizing sludge reduction, harmless, stable and resource utilization, and promoting the coordinated development of China's environmental protection cause and circular economy
