According to relevant data, the amount of sludge generated by my country's sewage treatment plants reached 300 million tons in 2010. Because sludge dehydration requires biochemical and flocculation treatment, and dehydrated sludge contains large amounts of cellular and adhering water, the existing equipment and technology in nearly all sewage treatment plants can only reduce the sludge moisture content to around 80%. Reducing the sludge moisture content to below 50%, which is required for incineration, is extremely costly. Consequently, nearly all sewage treatment plants in my country are forced to primarily landfill or stockpile their sludge, causing serious environmental pollution.
