摘　　要：对悬浮填料型活性污泥生物脱氮工艺进行了研究。试验期间进水有机物浓度波动较大,出水COD浓度基本在30mg/L左右,COD的总平均去除率达到86.98%,氨氮平均去除率达到72.25%,出水平均为8.15mg/L;总氮的平均去除率达到48.39%,出水浓度平均为17.63mg/L。因此利用该反应器对生活污水进行脱氮处理是可行的。The biological nitrogen removal efficiency with the suspended carriers activated sludge reactor is studied in this paper. In the experiment, the influent is domestic sewage. Although the concentration of organic compounds change clearly, the effluent concentration of COD can keep 30mg/L and the average efficiency of COD is 86.98%. The reactor has good efficiency to ammonia and its average efficiency is 72.25% .The average concentration of ammonia is 8.15mg/L. To total nitrogen,the efficiency can achieve 48.39%, the average concentration is 17.63mg/L so we can draw a conclusion that it is possible to remove nitrogen using this reactor.
