摘　　要：造纸废水污染十分严重,其综合治理一直是国内外造纸工业和环保界的研究热点。作者对近几十年国内外造纸废水,尤其是造纸黑液治理的方法,如黑液碱回收法、酸析法、絮凝法、膜分离法、生物法、氧化法等进行了详细评述,认为生物法是解决我国造纸工业水污染的最终出路。同时首次提出将超临界水氧化技术应用于造纸黑液的治理,具有潜在的可行性和十分重大的意义。The pollution caused by papermaking wastewater is very serious. The comprehensive treatment of that has been the focus point for papermaking industry and the environmental protection field. The paper reviews the technology of papermaking wastewater, especially black liquor treatment in recent decades, such as methods of soda recovery, acid recovery, flocculation, membrane separation, biological method and oxidation etc. Biological method is regarded as the ultimate outlet for the solution of the pollution problem of papermaking industry in China. Meanwhile the application of supercritical water oxidation technology to the treatment of black liquor is pointed out for the first time, which has the potential feasibility and very important significance.
