Zusammenfassung:	The invention discloses a sludge treatment system and method. The system comprises a wet sludge bin, a mixer, a rotary drum dryer, an electric dust remover, a gas-solid separator, a sifter, a crusher, a dried sludge bin, a dried sludge dust bin, a coal mill and a subsequent treatment subsystem. The wet sludge bin is communicated with an inlet of the mixer, an outlet of the mixer and the electric dust remover are both communicated with an inlet of the rotary drum dryer, an outlet of the rotary drum dryer is communicated with an inlet of the gas-solid separator, an inlet of the sifter is communicated with an outlet of the gas-solid separator, an outlet of the sifter is respectively communicated with an inlet of the crusher, the drying sludge bin and the drying sludge dust bin, the dried sludge dust bin is respectively communicated with an outlet of the crusher and an inlet of the mixer, and the dried sludge bin is communicated with the coal mill. According to the invention, the rolling wet sludge is dried by ut
