摘　　要：分析了废纸造纸废水的主要来源和废水水质特点,并针对该类废水的污染特性,总结和评价了各种处理措施。研究表明,混凝沉淀法或气浮法可有效去除废水中SS的含量,提高废水的可生化性,是最普遍采用的预处理方法;厌氧与好氧组合的生物处理过程可充分利用两种处理工艺的优势,去除废水中大部分BOD_5、COD,以及部分含氯酚类化合物和可吸附有机卤化物(AOX),常作为废水的主体生物处理工艺;化学氧化法可进一步去除难生物降解有机物和色度,结合成本、运行管理等因素,常被采用作为造纸废水的三级处理手段。研究进一步指出,废纸造纸废水的回用和零排放是该行业未来发展的热点领域。Main sources and characteristics of regenerated papermaking wastewater were analyzed. Various treatment measures were summarized and reviewed according to the pollution characteristics of wastewater. Research results showed that SS content could be effectively removed from wastewater by coagulation precipitation or air float, and the biodegradability of wastewater could be improved, therefore it was the most widely used as a preprocessing method. The combination of anaerobic and aerobic biological treatment process, as the main process of wastewater treatment, could be made full use of the advantages of these two processes, and most of BODs, COD, parts of chlorinated phenolic compounds and adsorbable organic halides （AOX） could be removed. Through chemical oxidation method, stubborn organic matter and color could be further removed, and it was often used as tertiary treatment with consideration of factors such as＇cost, operation and management. Wastewater reuse and zero discharge are the future direction of this area.
