废弃瓷砖经再生加工后,制成一种具有比表面积大、机械强度和显气孔率高的再生滤料.实验研究该滤料在曝气生物滤池(BAF)中处理校园生活污水的挂膜规律以及处理效果.结果表明,启动挂膜20 d后,当生活污水进水COD为120～310 mg/L,BOD5为50～150 mg/L,NH3-N、TN的质量浓度分别为18～60、35～70 mg/L时,出水COD、BOD5和NH3-N、TN的质量浓度分别约为40 mg/L、20 mg/L和8、25 mg/L,去除率分别在75％、80％、80％、48％左右,表示此时曝气生物滤池挂膜成功.“,”A degeneration filter of a large surface area,high mechanical strength and high porosity was prepared after recycling processing of waste ceramic tile.Regularity of biofilm start-up and treatment effect of the prepared filter on the treatment of campus domestic sewage were studied in the biological aerated filter (BAF).The results showed that after 20 d of biofilm start-up,when sewage influent COD was 120～310 mg/L and BOD5 was 50～150 mg/L,mass concentrations of NH3-N and TN were 18～60 mg/L and 35 ～70 mg/L,respectively,the effluent COD and BOD5 were 40 mg/L and 20 mg/L,respectively,and mass concentration of NH3-N and TN were approximately 8 mg/L and 25 mg/L.The removal rates of COD,BOD5,NH3-N and TN were nearly 75％,80％,80％ and 48％,demonstrating the success of the biofilm formation.
