摘　　要：以钢渣为主要原料，添加少量黏土和造孔剂制备钢渣陶粒，用于生物接触氧化处理微氧反应器出水。结果表明．钢渣陶粒生物接触氧化工艺能同时去除COD和脱氮除磷。在接触氧化时间为2．5h，进水COD、TP、NH4＋-N、TN的质量浓度分别为20～86、0．8～6．0、8．2～31．4、9．9～33．2mg／L的条件下稳定运行，出水COD、TP、NH4＋-N、TN的平均质量浓度分别为18、0．6、0．2、3．5mg／L，满足GB 18918-2002的一级标准要求。Steel-slag ceramisites have been made by using steel slag as their main raw material and adding a small amount of clay and pore-forming agent, and have been applied to biological contact oxidation process for treating micro-aerobic effluent. The results show that COD, nitrogen and phosphorus can be simultaneously removed by steel- slag ceramisites-biological contact oxidation process. When it runs steadily under the following conditions：contact oxidation time is 2.5 h, mass concentrations of influent COD, TP, NH4＋-N and TN are 20-86,0.8-6.0,8.2-31.4, and 9.9-33.2 mg/L, respectively, the average mass concentrations of effluent COD, TP, NH4＋-N and TN are 18,0.6,0.2 and 3.5 mg/L,respectively, meeting the requirements of the first class of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant（GB 18918--2002）.
