Why does the pH of the effluent from Fenton’s process not increase but instead decrease?

The last edit to this post was made by Gorō’s Eight Trigrams Staff on 2015-8-27 at 08:23. The original poster was referring to the comparison of pH values when adding water and acid, but you later added two acidic substances as well: ferrous sulfate and hydrogen peroxide, which causes the pH value of the wastewater to drop significantly

Personally, I think this situation is impossible; could it be that the test results are incorrect?

Has acid been produced? ........

Is the ratio of the materials too extreme?

What is the dosage ratio? What kind of wastewater is being treated?

Is there a process of bubbling and stirring? After bubbling, the pH value drops by 0.2 to 0.3.
