PROBLEM TO BE SOLVED: To provide a coagulation device achieving the shortening of the coagulation treatment time of sludge with a simple configuration.SOLUTION: A coagulation device comprises: a housing tank 10 having a receiving side receiving a liquid to be treated before insoluble substance coagulation and a discharge side discharging the liquid to be treated after the insoluble substance coagulation and housing the liquid to be treated moving from the receiving side toward the discharge side while coagulating an insoluble substance; agitation means 20 where the moving liquid to be treated is agitated by a plurality of agitation members and mixed with a coagulant; and a plurality of partition plates 31, 32, 33 being disposed in the housing tank 10 and dividing the inside of the housing tank 10 into a plurality of chambers along a moving direction from the receiving side to the discharge side while ensuring the movement path of the liquid to be treated. The plurality of agitation members are disposed to be dispersed at one chamber interval in the plurality of chambers so that an agitation chamber disposed with at least one among the plurality of agitation members and a non-agitation chamber not being disposed with any one among the plurality of agitation members are alternately arrayed from the receiving side toward the discharge side.SELECTED DRAWING: Figure 2 |
