The invention discloses a treatment device for drying sludge through slag waste heat. The treatment device comprises a feeding conveying system, an air circulating system and a sludge drying system. The feeding conveying system is used for conveying raw materials to the sludge drying system, the air circulating system is used for conveying heat to the sludge drying system, and the sludge drying system is used for drying sludge. The sludge drying system is a rotary sludge dryer which is transversely arranged in an inclined mode. One end of the rotary sludge dryer is higher than the other end of the rotary sludge dryer. Waste heat of slag discharged by a garbage incinerator is utilized for drying the sludge, the sludge of a sewage treatment factory can be dried without consuming new energy, in this way, the drying cost is greatly lowered, and meanwhile basic conditions are provided for harmless, reducing and resourceful treatment of the sludge of the sewage treatment factory are provided. 本发明公开了一种利用炉渣余热干化污泥的处理装
