摘　　要：采用铁炭内电解-UASB-BAF组合工艺对草浆造纸中段废水进行处理.结果表明,组合工艺对草浆造纸中段废水的COD、色度、SS具有较好的去除效果,在5种试验工况条件下,COD、色度和SS的去除率分别可达83%～90%,75%～85%和88%～93%;UASB工艺可以提高造纸中段废水的可生化性,试验过程中,经UASB处理后B/C最大可提高到0.5左右.综上所述,铁炭内电解-UASB-BAF组合工艺可以有效去除草浆造纸中段废水中的污染物质,可望在草浆造纸中段废水处理领域得到广泛应用.Straw pulp and papermaking middle-stage wastewater is treated by the combination of internal electrolysis,UASB and biological aerated filter（BAF） process in the study.The results show that the combination treatment technology can remove COD,color and SS from the wastewater efficiently.Under five working conditions,removal rate of COD,color and SS reaches to 83%～90%,75%～85% and 88%～93%,respectively.Meanwhile,UASB can increase the biodegradability of the wastewater significantly.In the course of the experiment,ratio of B/C reaches to about 0.5 after UASB treatment.In summary,the combination technology can remove contaminant from straw pulp and papermaking middle-stage wastewater effectively,and it is expected to be widely used in this kind of wastewater.
