摘　　要：从造纸中段废水的处理现状出发,对造纸中段废水深度处理的必要性和紧迫性进行了总结,并以广泛研究和实际应用的废水深度处理方法为基础,对它们应用于中段废水深度处理的可行性进行分析。对于中段水的深度处理,如果采取单一的处理方法,物化法存在着成本高、吸附剂再生困难、污泥量大等缺点,生物法难于进一步降低COD,生态法受土地等条件的制约,有着应用的局限性。只有通过方法的联合,优势互补,才能做到经济性和实用性的统一。Based on current treatment condition, necessity and urgency of advanced treatment of paper mid-wastewater was analyzed. The current wastewater polishing treatment process was summarized, and their possibility applicable to paper mid-wastewater was analyzed. It was concluded that, single treatment had its disadvantages, for example, physical-chemical process had such disadvantage as high cost and large amount of sludge, biological process is difficult to reduce COD further, ecological process is limited by soil and climate. So it is only through combined process that the unification of economical efficiency and practicability can be achieved.
