摘要
对内循环三相生物流化床处理生活污水进行了试验研究,探讨了生物膜的形成和水力停留时间及曝气量对处理效果的影响。结果表明：在HRT为6h,曝气量为0.6m3/h,进水COD和NH4＋-N分别为240.2~298.7mg/L和29.1~68.9mg/L条件下,平均COD去除率为83%,NH4＋-N去除率为95.1%。
An experimental study on the domestic wastewater treatment using an inner loop three phase fluidized bed reactor was presented in this paper.The formation of biofilm and effects of hydraulic retention time and volumetric gas rate on efficiency of wastewater treatment were studied.The results showed that the average COD and NH＋4-N removal rate were 83% and 95.1% under the condition of HRT 6h,volumetric gas rate 0.6m3/h and the influent COD and NH＋4-N concetration of 240.2～298.7mg/L and 29.1～68.9mg/L repectively.
