AI Technical Summary
Technical Problem
The problem of inaccurate pH adjustment in existing wastewater treatment is mainly due to the inaccurate feedback signal caused by damaged pH probes, failure to calibrate or clean them in a timely manner, which affects the wastewater treatment process.
Method used
A wastewater pH adjustment device is used, which connects at least two pH meters to the control system. The dosing solenoid valve and dosing pump are controlled by the switching signals of multiple pH meters to achieve precise adjustment of the pH value in the reaction tank, including the addition of acid or alkali.
Benefits of technology
This reduces pH adjustment errors, enables precise control of pH values within the reaction tank, and improves the reliability and accuracy of wastewater treatment.

Abstract
The application provides a wastewater PH adjusting device and method, and belongs to the technical field of wastewater treatment, and comprises at least two PH tables, a dosing electromagnetic valve and a dosing pump; the at least two PH tables, a control system, the dosing electromagnetic valve and the dosing pump are connected according to a control principle diagram; the control system controls the dosing electromagnetic valve and the dosing pump according to on-off quantity signals output by the at least two PH tables, and adds or stops adding chemicals into a reaction tank; probes of the at least two PH tables are installed in the reaction tank at a predetermined interval. The on-off quantity signals output by the multiple PH tables are used to control the dosing pump, so that the probability of error is reduced, and the PH value in the reaction tank is accurately adjusted.
