摘要
In order to improve ammonia removal capability from wastewater, zeolite was modified with heat and biofilm in this paper. The results showed that the adsorption capacity of heat modified zeolite could be reach mean value of 120.18meq/100g, which was 1.55 times than virgin zeolite. The results of bench scale experiments also showed that the data in the experiments were in line with Langmuir isotherms for ammonium ion absorbed onto heat modified zeolite. Moreover the biofilm which attached on the surface of heat modified zeolite only modified the surface feature of modified zeolite, while ion-exchange and diffusion procedure were not affected.
