摘要
针对传统AB工艺在生物脱氮除磷方面的碳源相对不足问题,本试验采用改进AB工艺处理城市污水,以强化传统AB工艺的生物脱氮除磷功能。平行对比试验结果表明:改进AB工艺可以显著提高传统AB工艺的生物脱氮除磷功能,在进水COD浓度250～620mg/L,NH3-N 45～70 mg/L,TN 60～90 mg/L,TP 7～12 mg/L的条件下,改进AB工艺对COD、NH3-N、TN和TP的平均去除效率分别达到82.1%、90.3%、79.8%、90.61%,出水COD、NH3-N和TP等各项污染指标均能实现达标排放。
A modified AB process was used to treat municipal sewage in this paper in order to improve nitrogen and phosphorus removal efficiency by the traditional AB process. The results of the parallel bench-scale experiment showed that the modified AB Process could properly solve the carbon resource shortage problem aiming at the traditional AB process and enhance the biological nitrogen and phosphorous removal, and under the conditions of the influent COD concentration of 250-620mg/L,the influent NH3-N concentration of 45 -70mg/L, the influent TN concentration of 60-90mg/L and the influent TP concentration of 7 - 12mg/L, COD, NH3-N, TN and TP removal efficiencies reached to 82.1% ,90.3%,79.8% and 90.61% respectively. The treated effluent met the National Wastewater Integrated Discharge Standard.
