| 摘 要： | 不同填料曝气生物滤池在相同条件下进行挂膜试验。进水流向为上流式,挂膜方式为复合接种挂膜,即先用活性污泥闷曝接种,然后逐步提高进水流速,直到滤料表面形成稳定的生物膜。结果表明:33 d后挂膜成功,在温度为16～24℃,水力停留时间(HRT)为1 h,DO为6 mg/L的情况下,陶粒BAF对CODMn和NH3—N的去除率分别为23%和80%;沸石BAF的去除率分别为27%和84%;组合填料BAF去除效果最好,去除率分别为32%和92%。

| Abstract: | The start-up of biological aerated filter(BAF) was compared by different fillers.Flow direction is upflow.The filter was filled with activated sludge,and oxygen was supplied by the air compressor,and the primary clarifier effluent and the secondary clarifier effluent of a wastewater treatment plant were fed to the different biological aerated filters,with incremental flow rate of feed water,until the media of biological aerated filters were covered with stable biofilm.The results showed that the start-up of... |
