摘要

In this paper, long-term (>8 month) results of ammonia removal in biofilters was studied. Compost was used as the biofilter medium and activated carbon as an added material. The ammonia removal was normally >95/100 at influent ammonia concentrations of 20-500 ppmv. According to the test results, the influent ammonia concentration should be <200 ppmv (0.1570 g-ammonia/kg-media per day) so that the effluent concentration of ammonia is <1.0 mg/m~3 (the emission standard of China), and the biofiltration system can achieve good long-term performance.
