摘　　要：以三阶段两相厌氧-生物接触氧化为流程的生化法处理皂素生产综合废水,对厌氧后的出水进行硝化,实验室小型生物接触氧化池在水力停留时间(HRT)为4 d时,氨氮可由300 mg·L-1左右降至120 mg·L-1以下;工业性现场试验结果,生物接触氧化池HRT为1 d时,氨氮平均去除率为61%,出水浓度一般只能达到150 mg·L-1左右,最好可达120 mg·L-1。好氧出水中氨氮的进一步去除,需通过催化氧化的深度处理。We treated with saponin production mixed wastewater through bio-chemical technique grounded on combined process of two-phase anaerobic reaction with three stages and bio-contact oxidation. During aerobic nitrification of anaerobic effluent, it showed that the concentration of NH3-N could fell from around 300mg·L^-1 to below 120 mg·L^-1 in laboratorial bio-contact oxidation reactor when HRT was four days; From the result of industrial trial, the average removal rate of NH3-N was 61% and its effluent concentration generally just reached up to about 150 mg·L^-1 and the best effect was 120 mg·L^-1 when HRT was one day. Therefore, further removal of NH3-N in aerobic effluent requests deep treatment with catalyze oxidation.
