摘　　要：采用两级厌氧-好氧-厌氧氨氧化组合工艺处理金霉素和淀粉生产混合废水。连续272d现场试验结果表明,当原水CODCr为4000～16000mg/L,氨氮浓度为100～800mg/L(均值为530mg/L),总氮浓度为200～1000mg/L(均值为624.4mg/L)时,该组合工艺对CODCr去除率为94%～98%,对氨氮和总氮去除率均值分别为96.9%和89.8%。出水CODCr、氨氮和总氮浓度均值分别为514、15.6和59.2mg/L。组合工艺可有效削减有机物负荷,减轻后续深度处理的负担,同时通过生物处理除氮降低了常规物化脱氮的运行费用和投资成本,且出水氨氮和总氮浓度均满足GB21903—2008《发酵类制药工业水污染物排放标准》要求。A full-scale test was conducted with a process combining two-phase anaerobic, aerobic and ANAMMOX to treat mixed wastewater from chlortetracycline and starch production. 272 days of continuous experimental result demonstrated that the removal rate of CODcr, ammonia and total nitrogen （TN） of the combined process was 94%- 98%, 96.9% and 89.8% when the influent CODcr, ammonia and TN were 4 000-16 000 mg/L, 100-800 mg/L （ average value 530 mg/L） and 200-1 000 mg/L（ average value 624.4 mg/L）, respectively. The effluent average CODcr, ammonia and TN concentration were 514, 15.6 and 59.2 mg/L, respectively. The combined process could effectively reduce the organic load, the burden on the follow-depth treatment, and also the operating and investment costs of conventional materialized denitrification by using biological treatment. The ammonia and TN of effluent could meet the Discharge Standards of Water Pollutants for Pharmaceutical Industry Fermentation Products （ GB 21903-2008 ）.
