Abstract
This digestion system comprises: a digestion tank for digesting organic materials of excess sludge by means of anaerobic bacteria; first piping for supplying the excess sludge to the digestion tank; second piping having a greater pipe diameter than the first piping; a first storage tank which communicates with each of the first piping and the second piping and stores the excess sludge transferred from the second piping; a transfer means which continuously transfers, for a predetermined time, the excess sludge stored in the first storage tank to the digestion tank through the first piping; and a heater which heats the excess sludge inside the first piping by means of a fluid.
