摘要: 用充填陶瓷滤料的曝气生物滤池研究碳和氮代谢特性。曝气生物滤池进水氨氮为52 mg/L左右、COD为100 mg/L左右和回流比为200%时，经过20多d的运行，出水氨氮小于0.05 mg/L、COD小于25 mg/L、亚硝态氮为4.7 mg/L和硝态氮为7.1 mg/L，COD去除率达75%，氨氮去除率达99.9%，总氮去除率达78%；过大和过小的回流比对曝气生物滤池的运行性能都是不利的。研究成果可以应用于一般城市污水以及含低COD、高氨氮工业废水的处理。

Abstract: Carbon and nitrogen metabolic characteristics were studyed in biological aeration filter (BAF) reactor filled with expanded clay. After the startup operation of 20 d, the effluent ammonium nitrogen below 0.05 mg/L, COD concentration below 25 mg/L, nitrite nitrogen 4.7 mg/L and nitrate nitrogen 7.1 mg/L were obtained with the influent ammonium nitrogen concentration about 52 mg/L, COD concentration about 100 mg/L and inner recycle ratio 200% in BAF reactor. The removal rates of COD, ammonium nitrogen and total nitrogen were up to 75%, 99.9% and 78%, respectively. Bigger or smaller inner recycle ratio was unsuitable for running of BAF reactor. This technique can be applied to treat urban wastewater and industrial wastewater with low COD and high ammonium concentrations.
