The use of power plant waste heat medium pressure saturated steam as sludge drying of heat source. thermal sludge dry of evacuation to heat and power plant CO combustion. The sludge CO combustion technology  in Suzhou Industrial Park sewage treatment works have obtained successful application. The project realizes sludge thermal drying by combining the organic system and thermal power plant system. Through the engineering of sludge heat drying CO combustion characteristics and the design of research and analysis, we can  provides reference and reference for treatment of similar sludge.
