全沈降させるものである。This is done by spraying a chemical conversion treatment solution containing zinc monophosphate as the main component onto the surface of the base body (or chassis frame), and depositing all of the zinc phosphate on the surface of the core body, forming a zinc phosphate film. At the same time, this treatment reaction produces ferrous phosphate, and the ferrous phosphate turns into ferric phosphate (sludge) due to the oxidizing action of the accelerator. The above-mentioned coagulation-sedimentation device is a method that completely continuously removes the ferric phosphate (sludge) generated in this treatment reaction, and the waste liquid containing ferric phosphate is stored in the tank of the coagulation-sedimentation device. The ferric phosphate is allowed to remain there for a sufficient period of time to completely settle out the ferric phosphate as sludge.

A riser pipe 1 in which the chemical conversion treatment liquid as waste liquid sent from 8 is placed horizontally at the bottom of a tank 11.
Ferric phosphate (ferric phosphate (
sludge) to settle at the bottom of the tank. Then, only the tap water of the chemical conversion treatment liquid (corresponding to the treatment liquid as coagulation sedimentation device #t18) that overflowed into the overflow ml 1 m 1111 after the sludge and ferric acid (sludge) were sedimented and removed. While returning to the chemical conversion tank 8 via the piping system 14, the ferric phosphate (sludge) that has settled and accumulated at the bottom of the tank is sent to the filter 16VC in the bong 115.
The sludge that is sent out, dehydrated, dried, and solidified is dropped into a sludge receiver 17 such as a drum can.

A bubble cutter plate is installed near one side wall of the tank, while two narrow iser tubes are placed in the gap between the side wall and the bubble cutter plate to introduce the waste liquid into the entire tank. It is said that

In the tank 11, a flat foam cutting plate 16 is vertically disposed at a position near the side wall 11b from the center of the tank on the opposite side of the overflow tank 11a, and these side walls 1], In order to install a chemical conversion treatment liquid inlet as a waste liquid in the gap between b and the bubble cutter plate 16, a riser pipe 23tl for introducing the entire chemical conversion treatment liquid is placed vertically in the above gap and its blowing It is installed so that the outlet 28& is aligned with the foam cutter plate 16. Incidentally, ltim is a support bracket for fixing the bubble cutting plate 16't to the wall 11b.

At the same time, a shower-like blast of rice fields occurred. At this time, the ferric phosphate (sludge) contained in the chemical conversion treatment liquid is removed from the foam cutting board 1.
It collides with 8 with force, separates, and settles to the bottom of the tank. Also, at this time, turbulence occurs due to the blowing out of the chemical conversion treatment liquid.

％と飛躍的に同上した。The bubbles generated by air entrainment are suppressed by the bubble cutter plate 16 and are generated only in the area defined by the one side wall 11b and the bubble cutter plate 16. The skin sludge often settles and accumulates at the bottom of the tank, and once accumulated, most of the blown-up skin sludge is eliminated. Based on the above configuration, the present inventor conducted a test and found that when the flow rate of liquid from the riser pipe 28 was 1120 It/min, the sludge removal efficiency was 95.5% compared to the conventional 29.8%.

ｈできる効果がある。As described above, according to the present invention, the bubble cutter plate is arranged vertically in the tank, and the riser pipe is arranged between the bubble cutter plate and the side wall of the tank, thereby reducing turbulence in the tank. It is possible to prevent sludge from being blown up due to flow, work, and entrainment, thereby greatly increasing the sludge recovery and removal rate, and preventing clogging of the piping system.
It has the effect of allowing h.
