Abstract

PURPOSE:To obtain bed soil for raising seedling having high quality at a low cost, by treating granular carbonized sludge with phosphoric acid and mixing the treated sludge with soil. CONSTITUTION:Sludge discharged from a paper mill is treated with a sludgetreatment apparatus and the obtained pulp sludge is calcined at about 900 deg.C in a calcination furnace to obtain carbonized sludge. The carbonized sludge is classified with a classifier to select granular carbonized sludge. 1kg of the granular carbonized sludge is mixed with about 800cc of liquid phosphoric acid having a concentration of about 75%. The resultant phosphoric acid-treated carbonized sludge is mixed with soil such as red clay, volcanic ash soil or sand soil.
