  • 摘要: 通过在传统A/O工艺好氧池投加聚氨酯填料组成A/O-生物膜复合工艺,建立了一套中试系统,以探讨处理实际煤化工高氨氮工业废水的可行性。结果表明该复合工艺具有很好的抗冲击负荷能力,并且在低温条件下仍能维持很高的去除效果。在温度为10℃以上、进水COD浓度为350~1 100 mg/L、氨氮浓度为80~280 mg/L时,出水COD和氨氮浓度始终维持在60 和10 mg/L以下,去除率分别可达到90%和95%以上。低温对系统中悬浮污泥活性的影响比生物膜更大。常温条件下(20℃)生物膜的COD和氨氮降解速率分别为悬浮污泥的1.4和2.5倍,低温条件下(10℃)分别为3.1和3.0倍。
    Abstract: This study constructed an A/O-biofilm pilot system by adding polyurethane media into the aerobic tank of conventional A/O process and investigated the feasibility of treating coal chemical industrial wastewater containing high strength ammonia by this system.Results suggest that this system had a high resistance to shock loading and could reach high removal efficiency at low temperatures.When the system temperature was above 10℃ and the influent COD and ammonium-nitrogen concentrations were respectively fluctuated between 350 to 1 100 mg/L and 80 to 280 mg/L,the removal efficiencies for both COD and ammonium-nitrogen were above 90%,and the effluent COD and ammonium-nitrogen concentrations were always maintained below 60 and 10 mg/L,respectively.Low temperature had a greater impact on the biodegradation activity of suspended sludge than that of biofilm.At room temperature (20℃),the biodegradation rates of COD and ammonium-nitrogen for biofilm were about 1.4 and 2.5 times of that for suspended sludge,while these values changed respectively to 3.1 and 3.0 times at a low temperature (10℃).
