Effect of Activated Attapulgite on Ammonia-Nitrogen Removal

Article Preview

Abstract:

The removal of ammonia-nitrogen (NH4+–N) in water by activated attapulgite was investigated. The study focuses on the effect of different activated attapulgite. The influence factors include microwave power, heating time and pH value in solution. The results show that heating 4 minutes, microwave power of 89 watts, and pH value of 9 are the best conditions to remove NH4+-N in the wastewater and the removal efficiency can above 80%. The attapulgite activated by microwave and alkali can remove NH4+-N in breeding waste effectively and the removal efficiency can reach 84.15%.
