The Chemical Engineering Theory section is now launching a \"One Question per Day\" campaign to help 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! Wishing everyone a happy Christmas! Answers to the questions in the \"One Question per Day\" campaign can be viewed directly; the thread will be closed after 1 day ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: Why does the alkaline solution need to be heated during the regeneration of the anion exchange bed in winter? Answer: During the regeneration of the anion exchange bed, the rate at which silicate ions are displaced from the resin layer is slow; by increasing the temperature of the regeneration solution, the ability to displace silicate ions can be improved, which enhances the effectiveness of silicate regeneration and reduces the regeneration time ； At low temperatures, it affects the replacement rate between the anionic resin and the alkali solution, resulting in a decrease in the degree of regeneration. Therefore, the alkali solution must be heated when regenerating the anionic resin in winter.
