| Abstract: | A large quantity of sludge is produced during the treatment of waste water in China annually, whose complicated composition and high moisture content restrict its effective utilization. So the decreasing moisture content of sludge is a key to its development and utilization. The paper analyzed the sludge heat drying techniques and its economic feasibility, and elaborated four aspects including the typical of sludge drying process and equipment, environmental pollution and control of the drying process, the tail gas treatment of sludge drying and sludge drying efficiency. The sludge heat drying technology and its process were analyzed. The results indicated that the sludge heat drying was an effective treatment to achieve economic and environmental benefits. |
