[0026] like Figure 1 As shown, in this embodiment, a liquid inlet pipe 12 and a liquid outlet pipe 13 communicating with the interior of the regulating tank 1 are respectively provided on both sides of the regulating tank 1 .

[0027] In this embodiment, the regulating tank 1, the mounting plate 2, the alkaline stirring tank 3, the acidic stirring tank 4, the driven rotating rod 5, the first blade 6, the water inlet 7, the feeding port 8, the delivery pipe 9, the solenoid valve, the liquid inlet pipe 12 and the discharge pipe 13 are arranged so that the mounting plate 2 is fixedly connected to the regulating tank 1, the upper end of the driven rotating rod 5 is connected to the upper end surface of the alkaline stirring tank 3 or the acidic stirring tank 4 through a bearing seat, the water inlet 7, the liquid inlet pipe 12 and the discharge pipe 13 are provided with a control valve, and the feeding port 8 is provided with a threaded sealing cover for blocking the feeding port 8 after feeding to prevent External dirt enters the alkaline stirring tank 3 or the acidic stirring tank 4 through the feeding port 8. When the sewage flows into the regulating tank 1 from the liquid inlet pipe 12, alkaline powder and acidic powder are respectively fed into the alkaline stirring tank 3 and the acidic stirring tank 4 through the feeding port 8. At the same time, clean water is respectively input into the alkaline stirring tank 3 and the acidic stirring tank 4 through the water inlet 7. Then, the driven rotating rod 5 drives the first blade 6 to rotate to stir the solutions in the alkaline stirring tank 3 and the acidic stirring tank 4, so that the alkaline powder and the acidic powder are evenly mixed with the clean water to prepare alkaline solutions and acidic solutions with uniform concentrations.

[0028] When the acidity of the sewage in the regulating tank 1 is too high, the solenoid valve can be opened, and the alkaline solution in the alkaline stirring tank 3 can be quantitatively discharged into the middle of the regulating tank 1 through the delivery pipe 9 to mix with the sewage. The delivery pipe 9 can discharge the alkaline solution into the middle of the regulating tank 1. The alkaline solution directly discharged into the middle of the regulating tank 1 is conducive to subsequent stirring and mixing, and can make the alkaline solution diffuse more quickly and evenly in the sewage, avoiding the local concentration of the sewage solution being too high or too low, affecting the accuracy of the pH value; when the alkalinity in the sewage is too high, the acidic solution in the acidic stirring tank 4 can be added to the regulating tank 1 through the delivery pipe 9. When the pH adjustment of the sewage in the regulating tank 1 is completed, it can be discharged through the drain pipe 13.

[0029] In this embodiment, the active rotating rod 10, the second blade 11 and the driving assembly are arranged so that the active rotating rod 10 is connected to the mounting plate 2 through the bearing seat; the driving assembly can drive the active rotating rod 10 and the driven rotating rod 5 to rotate synchronously.

When an alkaline solution or an acidic solution is added to the regulating tank 1, the active rotating rod 10 and the driven rotating rod 5 can be kept rotating synchronously, so that the solution in the alkaline stirring tank 3 or the acidic stirring tank 4 is always kept in a mixed state, and at the same time, the sewage can be stirred so that the sewage and the alkaline solution or the acidic solution are quickly mixed.

[0032] Among them, before the alkaline solution or acidic solution is added to the regulating tank 1, the active rotating rod 10 has begun to stir the sewage in the regulating tank 1 in advance.
