Abstract
PURPOSE: To ensure an extremely high-efficiency filtering and hardening for the sludge, by adding and mixing the hydraulic cement-group material into the sludge prior to the filtering process of the sludge.
CONSTITUTION: The hydraulic cement-group material is added and mixed into the sludge before filtering the sludge. And then the sludge is filtered preferably between the initiation and completion of setting of the above-mentioned cement-group material. The hydraulic cement-group material is composed preferably by the 100pts. wt. Portland cement, 15W50pts.wt. basic aluminum sulfate, 20W60pts.wt. gypsum and 1W40pts.wt. lime respectively. And a part or the whole of the above-mentioned basic aluminum sulfate can be substituted with the composition of the 70W30pts. wt. aluminum sulfate and the 30W70pts.wt. amorphous aluminum hydroxide receiving the heat covering pressure of ≥125°C in terms of the anhydride conversion value.
