Abstract：ThisarticleintroducesaCSCRdesulfurizationanddenitrificationmaterialcirculationsystemthatisprovided through a multi-loop system transformation， which can extend the storage time of activated carbon without increasing the capacityof theactivated carbon storage tank.Itcan improve the eficiency of activated carbon circulation tank capacity by 28% ，thereby increasing the maintenance time by 64.2% . This provides a strong guarantee for completing maintenance work.Incaseof emergencies，whenitisnecessarytoinjectactivatedcarbonfromtheabsorptiontower or the desorption tower into the activated carbon circulation tank，the modified discharge slope pipe can make the faulthandling more composed.Itachieves on-line maintenance constructionand enhances theflexibilityof theentire activated carbon circulation system.

Key words： CSCR desulfurization and denitrification; circulation system; discharge slope pipe; tank capacity; maintenance time
