- Abstract:
- The situations of sewage sludge treatment in Beijing including the technologies, the scales and state-of-the-art in this field were investigated, combined with the sewage treatment situation. The sludge treatment projects in Beijing basically met the treatment needs of sludge from municipal sewage plants among the whole city, which also fit the requirements of the “13th-five Year Plan” ecological environmental protection plan. Anaerobic digestion was the main sludge treatment in the central urban area of Beijing.Meanwhile, in the surrounding area of Beijing, the sludge was mainly treated by aerobic fermentation, which may be assisted by other processes. The disposal is mainly processed by land utilization, and the use of construction materials could also be a solution. This paper analyzes the current situations of sludge treatment and disposal in Beijing, the situations of sludge treatment and disposal at home and abroad, and the characteristics of domestic mainstream sludge treatment and disposal process. We also analyzed the matching degree between the sludge treatment route in Beijing and the relevant national technical guidelines, and the possibility of popularization and promotion of process application. Furthermore, this work analyzes and summarizes the sludge treatment capacity, treatment cost and disposal outlet in Beijing. This work could provide a certain reference for other cities on the selection of sludge treatment and disposal strategies in China.
