PURPOSE: A processing method of soil covering using sludge is provided to process large amount of sludge in short time and to increase efficiency of soil covering using sludge by increasing moisture elimination rate inside the sludge. CONSTITUTION: A processing method of soil covering using sludge includes a curing step which comprises the following steps: mixing sludge with curing agent; adding the mixture to a curing device; and drying through hot air. The curing step comprises first and second curing steps which are serially connected. The first curing step comprises the following steps: injecting the mixture into a container type main body and dropping; drying the mixture dropped through hot air; and immediately discharging the dropped mixture. The second curing step comprises the following steps: mixing and drying step (650) which dry the mixture which is dropped into the container type main body and the mixture which is dropped and loaded (660) by inserting and dropping the mixture into the container type main body while supplying hot air without discharging the mixture which is dropped; and discharging (670) the loaded mixture.
