Abstract

PURPOSE: To heighten the efficiency of sludge collection by a method wherein a coagulant is added into the sludge located at a position distant from a sludge discharge port of the sedimentation separator.
CONSTITUTION: When sludge 1 is collected on the bottom of a thickner A, a coagulant is added from a small hole at a nose portion a of a coagulant injecting pipe 3 disposed to a scraper truss 2. The coagulant added to the sludge is agitated by means of a scraper 4 mounted to a lower end of the truss 2 with the revolution of the scraper truss, coagulation action is formed, and minute grains are flocked. The sludge flocked in such a manner is successively collected toward a sludge discharge port 5 because a gradient is made up toward the sludge discharge port 5 in the bottom of the tank and the scraper truss is rotated, and the sludge collected on the bottom of the tank is flocked in the process.
