| description | PROBLEM TO BE SOLVED: To provide a method and apparatus for treating sludge capable of markedly enhancing the treatment capacity of excess sludge in a biological treatment tank. SOLUTION: In the sludge treatment method for treating the excess sludge generated when wastewater is biologically treated in the biological treatment tank 1, the excess sludge is solubilized at predetermined temperature under predetermined pressure in a solubilization apparatus 4 while a predetermined amount of oxygen is supplied and the treated matter is returned to the biological treatment tank 1. Before the excess sludge is solubilized, the concentration thereof is adjusted by a concentration adjusting means 3. |
