中文摘要
      采用厌氧滤池(AF)+曝气生物滤池(BAF)工艺处理树脂化工废水,曝气生物滤池以陶粒为生物载体,进水COD为200~300 mg·L-1,实验规模均为2~4 L·d-1. 实验表明,采用AF+BAF工艺对化工园区尾水有较好的处理效果,在AF停留24 h,BAF停留12 h的条件下,COD的去除率最高可达73.4%,NH4+-N的去除率达到93.8%. 通过气相色谱-有机质谱联用仪(GC-MS)和三维荧光光谱分析发现,系统对小分子有机物和微生物代谢产物的去除显著,但对饱和烷烃和含氮杂环类物质去除效果不佳. 变性梯度凝胶电泳(DGGE)谱图显示,AF中的微生物种类比原废水厂上流式厌氧池(UASB)中更为丰富,表明化工园区废水采用二次厌氧效果明显.
英文摘要
      The anaerobic filter (AF) and biological aerated filter (BAF) were employed to treat the effluent in a sewage plant of the resin and chemical industry park. The ceramsite was used in BAF. In this study, the influent COD was 200-300 mg·L-1 and the pilot model scale was 2-4 L·d-1. According to the results, the AF-BAF treatment had a good effect on organic wastewater. When the AF HRT was 24 h and BAF was 12 h, the removal of COD reached 73.4%, and that of NH4+-N reached 93.8%. From gas chromatography-mass spectrometry (GC-MS) and three-dimensional fluorescence analysis, it was found that small organic molecules and microbial metabolites could be removed effectively. However, there was no obviously effect on the removal of saturated alkane and nitrogenous heterocyclic compounds. From the denature gradient gel electrophoresis (DGGE) spectra analysis, it was shown that there were more kinds of microorganism in the sludge of the AF than in the up-flow anaerobic sludge bed (UASB), which indicates that the AF-BAF system is more effective on treating effluent in a sewage plant of the resin and chemical industry park.
