| Abstract |
| This study was conducted to removal of low ammonia nitrogen. ball-type zeolites were used to adsorb ammonia nitrogen and regenerated simultaneously by attached nitrifiers. Prior to main experiment, adsorption rate and amount of adsorption was confirmed by pseudo second-order kinetic model and Freundlich, Langmuir isotherm models. Comparison of normal ball-type zeolite and nitrifiers-attached ball-type zeolite were proceeded in order to evaluate for nitrification(biological regeneration). And continuous operating experiment was operated in 1.6 L reactor at empty bed contact time(EBCT) 25 minute to check the possibility of continuous operation. In the result of experiment, only nitrifiers-attached ball-type zeolite was occurred nitrification(biological regeneration). And continuous operating experiment result during 32 days, it could constantly adsorbed the ammonia nitrogen during operating time. |
