Why does the pH rise to around 10 after 1 hour of micro-aeration in a micro-electrolysis pilot test?

1L of water, pH: 3–3.5; the iron and carbon levels are just at the appropriate level. After aerating with a small aerator for one hour, the pH rises to around 10. The same result was obtained in several small-scale tests – I’m not sure what the reason is
The author of this suggestion should start by analyzing the specific components of the wastewater to determine whether there are volatile weak acids, or substances that will produce an alkaline environment as a result of reactions. It’s impossible to give an answer based solely on the description.
