摘要:
采用以牡蛎壳为填料的内循环曝气生物滤池,对模拟水源水中氨氮进行处理,考察了水力停留时间、曝气量、pH值等因素对氨氮去除效果的影响.结果表明,该系统在水力停留时间为4 h,曝气量为2.0 L /min,pH=7.5~8.0的最佳条件下,对氨氮的去除率达到90%以上,出水氨氮浓度达到《地表水环境质量标准》(GB 3838—2002)中Ⅱ类水体的水质标准.可见,牡蛎壳是一种较好的曝气生物滤池填料,内循环可以显著提高曝气生物滤池脱氮效果.
Abstract:
Internal Circulation Biological Aerated Filter (ICBAF) with oyster shell as the filler was employed for the treatment of ammonia nitrogen from simulated source water.The experiments were carried out to investigate the effect of hydraulic retention time (HRT),aeration rate and pH on the removal efficiency of ammonia-nitrogen.Results showed that oyster shells were good carriers in the ICBAF reactor,and the removal efficiency of ammonia-nitrogen was significantly enhanced by effluent recirculation.The optimal condition was HRT of 4 h,aeration rate of 2.0 L/min at pH 7.5~8.0,and the removal efficiency of ammonia-nitrogen reached higher than 90 %.The quality of the effluent reached the case II category surface water according to the standard GB 3838—2002.
