摘　　要：选取玄武岩纤维填料、弹性填料和组合填料,作为生物接触氧化工艺的填料,以COD、NH_3-N和总磷(TP)去除率为考核指标,对比印染废水的处理效果,分析各去除率指标间的相关性。结果表明,3种填料对COD、NH_3-N和TP的去除率总体上随停留时间的延长而提高,玄武岩纤维填料处理效果最好,在HRT为15 h时,COD、NH_3-N和TP的去除率分别达到67.26%,51.02%和72.11%。在微生物的协同作用以及C/N/P营养比影响下,COD与NH_3-N、TP的去除效果不一致,但达到一定的反应时间后均得到有效去除。Abstract： The treatment results of dyeing and finishing wastewater through biological contact oxidation process with basalt fiber filler, elasticity filler or combined filler are studied. Using COD, NH3-N and TP removal rates as evaluation indexes, the relativity of the indexes is analyzed. The results show that the removal efficiencies of COD, NH3-N and TP increase with the extension of time, the treatment result of ba- salt fiber filler is the best with COD removal rate of 67.26%, NH3-N removal rate of 51.02% and TP removal rate of 72.11% when HRTis 15 h. With the synergistic effect of microorganisms and the influence of nutrient ratio of C/N/P, the removal results of COD, NH3-N and TP are not consistent, but it can be re- moved effectively in a certain time.
