| Abstract: | The experiments studied the condition and mechanism of removing ammonia ions from municipal sewage by activated zeolite, besides activating natural zeolite. Results of this study indicated that activated zeolite could remove ammonia from municipal sewage. There were many factors that affected the treating process such as the concentration of the activating solution and ammonia in the municipal sewage, treating time, stirring velocity and pH value. The activated zeolite removed ammonia from municipal sewage by means of ion exchange and adsorption, but the former was predominant. |
