摘　　要：制浆造纸工业废水中含有大量不同种类的难降解有机物,常规生物处理后,多数难降解有机物未得到有效降解,导致生物处理后的出水色度高、污染物复杂、可生化性差,并具有生物毒性,难以达到排放标准,需经过后续处理后才能排放水体。结合制浆废水难降解有机物的研究现状,重点阐述物化处理技术和强化生物处理技术在制浆废水难降解有机物中的应用,并分析现有处理技术存在的问题,进一步提出相应的研究方向,为造纸行业的可持续发展提供技术支持。The pulping wastewater contains a large number of refractory organics, most of which cannot be not effectively degraded by conventional biological treatment. Instead, such treatment often leads to complex effluent components, with high chroma, poor biodegradability, and biotoxicity. It is difficult to meet emission standards and requires subsequent treatment before discharging water. Combined with the research of refractory organic in pulping wastewater, this paper focuses on the application of physic-chemical technology and bioaugmentation technology in refractory organics of pulping wastewater, and analyzes the problems of the current technology, and predicts potential development trend, as technical support for the sustainable development of the paper industry.
