Effect of Activated Attapulgite on Ammonia-Nitrogen Removal

摘要：

　　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%.
