Study on the Removal of Ammonia Nitrogen from Wastewater Using Microwave Coupled with Active Carbon
摘要
Abstract
[Objective] The study aimed to discuss the feasibility and optimal conditions of removing ammonia nitrogen by using microwave coupled with active carbon. [ Method] In the study, a novel process, microwave radiation coupled wilh active carbon, was applied to remove ammonia nitrogen from wastewater, and the effects of solution pH, air conditions, active carbon usage, microwave power and time on ammonia nitrogen removal were studied. [ Result] Microwave coupled with active carbon can remove ammonia nitrogen efficiently, and pumping air into the wastewater can also increase the removal rate of ammonia nitrogen to a certain extent. Higher pH, intensive microwave power and longer treating time could also increase the removal rate of ammonia nitrogen using microwave radiation coupled with active carbon, whereas the usage of active carbon contributed a small impact. It was proved that microwave coupled with active carbon was an effective method for the removal of ammonia nitrogen from wastewater. Meanwhile, orthogonal experiments results showed that the removal rate of ammonia nitrogen reached 92. 5% under the optimal conditions, that is, active carbon usage was 0.5 g, pH = 11, microwave power was 850 W, and microwave time was 4 minutes. [ Conclusion] The research provided a new method to remove ammonia nitrogen from wastewater, namely microwave coupled with active carbon.关键词
