A predetermined voltage is applied so that the potentials of 6a to 16c increase. Therefore, the electrolysis of water occurs as follows. Near the anode ··· 2H 2 O → 4H + + O 2 ↑ + 4e - near the cathode ··· H 2 O + 4e - → 4OH - + 2H 2 ↑ where turbidity component in the raw water is a colloidal charge However, since the water is lost in charge due to the electrolysis of water, oxygen gas is generated from the anodes 16a to 16c and hydrogen gas is generated from the cathodes 17a to 17c. Gas comes into contact with the turbidity component in the raw water, and the turbidity component floats on the treated water as flocs 27. Then, the floc 27 flows to the floc discharge port 8 while floating on the treated water in accordance with the flow of the treated water to the treated water discharge port 9, and is discharged from the floc discharge port 8 to be removed. Therefore, the turbidity component in the raw water is removed and the raw water is purified.

御する。Bacteria existing in the raw water are killed by applying the current of about 2 to 4 A / dm 2 to the raw water inside the electrolytic cell 7. In addition, chlorine ions present in the raw water become hypochlorous acid by electrolysis, which is also a secondary factor in killing the bacteria. Therefore, the bacteria in the raw water can be killed and sterilized in the electrolytic cell 7. Further, the sediment accumulated in the bottom 25 of the electrolytic cell 7 can be discharged from the sediment removal port 10 by appropriately opening the on-off valve 28 provided in the sediment removal port 10. The water treated by the electrolytic cell 7 is stored in a treated water tank 12 via a treated water discharge port 9 and a pipe 11. The control device 15 controls the opening and closing of the control valve 1 and the operation of the pump 2 based on an output signal from a water level sensor 13 provided in the treated water tank 12.
And the voltage between the anode 16 and the cathode 17 is controlled to keep the current flowing in the raw water constant.

という効果を有する。As described above, in the apparatus for purifying polluted water by electrolytic treatment according to the present embodiment, a plurality of anodes 16a to 16c and cathodes 17a to 17c made of an insoluble material are alternately arranged, and a space between each electrode is provided. Since the raw water of the polluted water is allowed to pass through, the contact between the generated gas and the inclusions (polluted substances) in the polluted water is promoted, and the polluted substances can be reliably removed from the raw water containing the polluted substances by the electric flotation method. . Also,
By supplying current to raw water, not only can many bacteria existing in raw water be killed, but also the anode and cathode are arranged alternately, improving the effective chlorine generation efficiency and allowing it to exist in water. It is possible to kill many bacteria. Further, each anode 16a to 16c and each cathode 17
By using an insoluble electrode for a to 17c, the electrode is not eluted by electrolysis, so that there is no need to replace the electrode, and since no coagulant is added to the raw water, water contamination by the coagulant is reduced. This has the effect of eliminating the need for consideration.

In addition, since the insoluble anode and cathode are used, the metal ions dissolved from the electrodes and the chlorine ions contained in the polluted water do not react with each other to form a metal salt compound. The chlorine contained in the polluted water can be effectively used for sterilization.
Furthermore, since the insoluble anodes and cathodes are arranged alternately, the contact area between the anode and the chlorine ions contained in the polluted water is increased, the efficiency of producing effective chlorine is improved, and many bacteria present in the water are increased. Can be killed, and furthermore, since no flocculant is added to the polluted water, water contamination by the flocculant can be prevented.
