摘　　要：通过以固定化曝气生物滤柱(immobilized aerated biofilter column,I-BAF)系统为基础,建立了一套硝化曝气生物滤柱与耐盐碳氧化曝气生物滤柱的串联运行系统。将硝化曝气生物滤池的化学需氧量(chemical oxygen demand,COD)与碳氧化生物滤池串联后达到更好的废水处理效果。在串联系统中,COD和NH_(3)-N的去除率分别为61%和86%。文中研究了碳氧化曝气生物滤池去除COD的过程,分析了有机物从芳环向长链或烯烃的变化趋势。在处理后的废水中,COD和NH_(3)-N含量分别被控制在60 mg/L和10 mg/L,且出水的水质能满足《城镇污水处理厂污染物排放标准》1级B标准(GB 18918—2002)。A set of nitrification aeration biological filter(N-BAF)which is connected in series with a salt-tolerant carbon oxidation biological aerated filter(C-BAF)is established by constructing an immobilized biological aerated filter(I-BAF)system.The results show that the series operation of the N-BAF and the C-BAF can achieve a better treatment effect.The serial system treats wastewater and the removal rates of the chemical oxygen demand(COD)and the NH_(3)-N are 61%and 86%,respectively.The organic matter components in the removing process of the COD by salt-tolerant C-BAF are studied,and the trend of organic compounds changing from aromatic rings to long chains or olefins is analyzed.After wastewater treatment,the COD and the NH_(3)-N are controlled at 60 mg/L and 10 mg/L,respectively.The effluent quality can meet the level 1B discharge standard of pollutants for municipal wastewater treatment plant(GB 18918—2002).
