摘要： 采用A2O法-生物滤池-絮凝沉淀耦合技术处理以抗生素类制药工业废水为主的混合工业废水，在不同水温下进行实验，考察水温对污水处理效率的影响. 结果表明，当水温10.0~36.8℃、进水化学需氧量(CODcr)和氨氮(NH3-N)及总磷(TP)浓度分别为183~785, 20.7~76.2和2.47~33.7 mg/L、设计流量为30.0 L/h时，CODcr, NH3-N和TP等污染物的平均生物去除率分别达64.6%, 55.7%和84.4%，出水CODcr, NH3-N和TP等指标全部达到《污水综合排放标准》(GB8978-1996)的一级排放标准. 水温变化对CODcr, NH3-N和TP等污染物的去除效率影响很小，10℃时微生物仍具有较高的代谢速率. 耦合工艺对水温变化的缓冲能力强，为严寒地区污水高效处理提供了新途径.

Abstract: The A2O-biological aerated filter-flocculation coupled technology was applied to treat antibiotics-based mixed industrial wastewater, and the effect of temperature on treatment efficiency studied. The results showed that when water temperature was 10.0~36.5℃, the concentrations of CODcr, NH3-N and total phosphorus (TP) were 183~785, 20.7~76.2 and 2.47~33.7 mg/L in influent and the flow rate was 30.0 L/h, the average biomass removal rates of CODcr, NH3-N and TP were 64.6%, 55.7% and 84.4%, respectively. The CODcr, NH3-N and TP in effluent achieved the first grade of comprehensive discharge standard for sewage (GB8978-1996). The change of water temperature had little effect on the removal efficiencies of CODcr, NH3-N, TP and other pollutants. The metabolic rate of microbes was still high even at 10℃. This coupled technology has strong buffering capacity to the change of water temperature, providing a new way to efficiently treat sewage in severe cold areas.
