摘要:
A method of dehydrating an organic sludge, which comprises adjusting the pH value of a sludge having a solids concentration in the range of from 0.5 to 8% by weight, to a pH of 5 or less, heating the thus adjusted sludge, mixing with the sludge an oxidizer capable of displaying oxidation ability within the acid region, and dewatering the sludge with a dehydrator.
