After used the macroporous adsorption resin for a certain period, when the adsorption ability is reduced or heavily polluted, then need to strengthen regeneration, the method is add 3~5% concentration Hydrochloric acid solution into the resin container and let the solution 10 cm above the resin layer and soak 2-4 hours, then carries on the elution column. Then continue use 3~4 BV same concentration hydrochloric acid solution go through the resin column, and then use pure water to wash until close to neutral. After that, use 3-5% sodium hydroxide solution Soak for another 4 hours. and then, wash and go through the column, again use 3~4BV same concentration of 3-4 bv sodium hydroxide solution go though the resin column. Finally, use pure water wash until the PH value is neutral, then se aside for use.
