摘要：
Using composite zeolite filter material independent preparation in the laboratory as an aeration biological filter material,and compared with ceramsite.The ammonia-nitrogen adsorption capacity of the above two filters were evaluated through the pilot test. The start-up of pilot scale CBAF (BAF filled with compound filter material) showed that the average NH4+-N removal rate of the first 5 days was 52.36% when the average influent NH4+-N concentration was 37mg/L. In steady operation condition, the average NH4+-N removal rate reached 83.51% and the average effluent NH4+-N concentration was 5.81mg/L, which could meet the first degree of national wastewater discharge standard (GB 8978-1996).
