In 2010, the sewage sludge production rate will be 178,500 t dried solids (ds) for Beijing and 294,000 t-ds for Shanghai, respectively. Beijing adopts a centralized system to stabilize 78% of her sludge in three rural Stabilization Centres. Aerated composting technique will be used. Shanghai on the contrary decentralizes the management plan to treat the sludge on site. Diverse treatment trains, such as aerobic/anaerobic digestion, drying, incineration, and composting will be applied. Production rate, treatment plan, and the associated costs, energy consumption, carbon dioxide emission, and risk assessment for heavy metals and pathogens on human health were evaluated in this report for sludges yielded in Beijing and Shanghai, China.
