Dynamic Regeneration of D301f Anion Exchange Resin to Remove Nitrate Nitrogen in Wastewater
Nitrate nitrogen in wastewater poses serious threat. D301f anion exchange resin can remove nitrate nitrogen in wastewater, its regeneration is one of the most important procedures, because regeneration efficiency has a direct impact on exchange capacity, water quality and regeneration agent consumption. D301f exchange resin column simulated nitrogen fertilizer plant wastewater (nitrate nitrogen300mg/L) for dynamic regeneration experiment. The results showed that, NH4OH regeneration agent dosage selected 3 to 4 times of theoretical amount more reasonable; regeneration solution concentration and temperature separately used 20% and 30°C better.
