【Daily Question】Principles of Chemical Engineering 526: Neutralization Tank (March 2)
Thread Content
The Chemical Engineering Theory section is launching the \"One Question per Day\" campaign starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent campaigns will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\" – we hope you will give it your active support~~~ Replies to the \"One Question per Day\" campaign can be viewed directly at **; the topic will be closed after 1 day! ! To encourage continued participation from everyone this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What should be the pH level of the water discharged from the neutralization tank? 6-9
During neutralization, it is essential to adjust the pH value of the wastewater to above 9, so as to keep the ferrous ions in the wastewater entering the biochemical tank at a very low level
