Abstract
PURPOSE: To render a sludge weak alkaline without using a neutralizing agent by a method wherein slaked lime is added to a waste sludge after exhaust water treatment and dehydrated by pressure to obtain a cake, thereafter the said cake is broken and treated by passing air until a specific pH value is attained.
CONSTITUTION: The slaked lime is added to waste sludge used in treating city water or sewage and pressurized by a filter press or the like to prepare the dehydrated cake with moisture of below 65%. Subsequently, the said cake is broken to particles with a particle size of below 10mm the pH of the cake is lowered to 8W9 by continuously passing air in an amount of 100W200l/min per ton. By this treatment, if weak alkaline waste sludge is thrown away, the environment such as river or the like is not in danger of pollution.
