PROBLEM TO BE SOLVED: To provide a sludge treatment system that adjusts easily a pH value of sludge obtained by solid-liquid separation.SOLUTION: A sludge treatment system includes at least a press unit, a liquid holding tank, a chemical agent supply unit, and pH adjusting means. The press unit serves to subject waste liquid discharged from a factory to solid-liquid separation. The liquid holding tank serves to hold a liquid obtained by the solid-liquid separation. The pH adjusting means serves to adjust a pH value of the liquid in the liquid holding tank. The chemical agent supply unit serves to send the pH-adjusted liquid in the liquid holding tank to the press unit. |
