SLUDGE TREATMENT METHOD AND APPARATUS FOR TREATMENT OF SLUDGE, AND SYSTEM FOR TREATING SLUDGE USING IT

摘要

PPROBLEM TO BE SOLVED: To reduce a running cost while increasing a solubilization efficiency of sludge, and carrying out a maintenance saving for a sludge treatment apparatus and a sludge treatment system using it. PSOLUTION: The sludge treatment apparatus 5 comprises an inflow port 6, an outflow port 7, a treated water inflow port 8, an electrolytic cell 12 and an ultrasonic wave treatment tank 13, wherein the sludge is fed to the cathode 16 side of the electrolytic cell 12, treated water flowing out from a drainage treatment system is fed to an anode 15 side, and after the sludge is subjected to alkali treatment by electrolysis on the cathode 16 side of the electrolytic cell 12, ultrasonic wave treatment is carried out.
