As shown, in the flocculation reaction apparatus according to the present embodiment, sludge (sludge) mixed with flocculant is filled into the space of the inner container 1 through the line mixer 60 connected to the inlet 5.

The sludge (sludge) mixed with the coagulant filled in the inner container 1 is mixed with each other by the rotation of the rod shaft 13 through the reducer 12 connected to the motor 11 driven by the manipulator 30, and mixed with each other. While being solidified by the chemical action of the flocculant is raised upward of the inner container (1).

In this stirring action, the first, second and third blades 15, 16 and 17 and the baffle 2 promote the formation of the vortex against the sludge in the inner container 1, thereby allowing the sludge and the sludge. The reaction is carried out while further promoting the chemical reaction between the flocculants to raise the sludge (sludge) aggregated with each other upwards.

Subsequently, the sludge (sludge) that has risen upward in a concentrated state through the flocculant moves toward the clearance gap A formed between the upper end of the inner container 1 and the outer container 3, and then the clearance gap A Flows into the single discharge stage (4).

The concentrated sludge (sludge) introduced into the single discharge stage 4 is discharged while being pressed toward the screen 8 by the strong centrifugal force action, and the moisture escaped from the sludge (sludge) is slits of the screen 8.

It consists of a rotating shaft 21 coupled to both ends of the connecting plate 14 and a brush 22 provided at equal intervals along the length of the rotating shaft 21 to contact the screen (8).

The coagulation reaction apparatus having the structure as described above implements the same function as the coagulation reaction apparatus shown in FIGS. 1 to 4, but has a slight difference in the discharge path of water and dehydrated sludge (sludge).

That is, when the flocculation reaction apparatus according to the present modification operates, the concentrated sludge (sludge) reacted with the flocculant through the stirrer 10 is pressed onto the screen 8 with strong centrifugal force while discharging the water in the sludge (sludge). Ascending toward the extension space portion 1a forming the upper portion of the inner container 1.

As described above, the water discharged through the screen 8 is collected toward the space formed by the outer container 3, and then discharged into the water tank 70 through the water outlet 6, and above the inner container 1. The dewatered sludge (sludge) collected toward the formed extension space portion 1a is discharged to the sludge accumulation part 80 through the dewatered sludge discharge port 7.
