The above device is only equipped with alkali solution, so it is not convenient to neutralize domestic sewage. At the same time, since the PH detection instrument is installed inside the pool, when a fault occurs, personnel are required to discharge the sewage in the pool and enter the pool for maintenance and replacement, which increases the difficulty of maintenance. In order to solve the above technical problems, we have designed a sewage treatment device that automatically adjusts the PH value. Utility Model Content

[0026] When in use, connect the device to an external power supply and a controller, connect the external sewage delivery pipeline to the liquid delivery pipe 2 and the liquid outlet valve 9 respectively, then pour the alkaline solution and the acid solution into the left and right sides of the liquid storage tank 5 respectively, and the sewage flows into the neutralization tank 1 through the liquid delivery pipe 2 for temporary storage. At this time, after the sewage submerges the HP detection sensor 25, the HP detection sensor 25 detects the pH value of the sewage and transmits the detected numerical information to the control box 22. When the HP detection sensor 25 detects that the pH value is acidic, the information is transmitted to the control box 22. After receiving the information, the control box 22 processes and controls the left electric valve 13 to open. At this time, the alkaline solution on the left side of the liquid storage tank 5 flows into the neutralization tank 1 through the left discharge pipe 3 to mix with the acidic sewage. Similarly, when the HP detection sensor 25 detects that the sewage is alkaline, the right electric valve 15 is controlled to open to allow the acid solution on the right side of the liquid storage tank 5 to flow into the neutralization tank 1 for mixing.
