The invention discloses a method for treating sludge by using movable skid-mounted equipment, which comprises the following steps: a conditioning step: conveying the sludge to a conditioning tank to be mixed with a conditioner; a dehydration step: feeding the conditioned sludge into dehydration equipment for dehydration; a sludge temporary storage step: feeding the dewatered sludge into a sludge storage bin for temporary storage; a drying step: feeding the sludge into a drying machine for thermal drying; a carbonization step: feeding the dried sludge into a carbonization machine for a pyrolytic reaction; a sludge carbon cooling and outputting step: cooling the sludge carbon generated by carbonization, and conveying the cooled sludge carbon to a sludge carbon bin for storage; and a biomass fuel energy supply step: before the drying step and the carbonization step, burning the biomass fuel in a drying hot-blast stove and a carbonization hot-blast stove, providing high-temperature flue gas for a drying machine a
