| 摘 要： | 将粉煤灰基质滤料用于曝气生物滤池,该滤料具有较高的比表面积和孔隙率,吸附性能良好,挂膜后生物相丰富。对于中等浓度的生活污水,当水力负荷和COD有机物负荷分别控制在1.53 m3/(m2.h)、3.68 kg/(m3.d)以下时,该曝气生物滤池COD和NH3-N去除率能稳定在85%以上,出水COD和NH3-N达到排放标准要求。该曝气生物滤池对进水水质水量的变动具有较强的抗冲击负荷能力。

| Abstract: | Fly ash filter material as main media of biological aerated filter(BAF) has large specific surface area,high porosity and perfect adsorption performance.Biofilm on the media was abundant with kinds of microorganism.For wastewater with medium concentration,when hydraulic load and organic load were controlled under 1.53 m3/(m2·h) and 3.68 kg/(m3·d) respectively,removal rate of COD and ammonia could stably be over 85% with the effluent meeting requirements of drainage standard.BAF has strong resistance capability to shock load of wastewater quality and quantity. |
