The major part of chromogenic lignin derivatives in pulping and papermaking wasterwater is difficult to be decolored, its color and COD are also high. Therefore, the effluent from secondary treatment must be advanced treated for further reducing the color and COD, improving effluent quality, to meet the requirement of the newest " discharge regulation of water pollutants for pulp and paper industry" ( GB3544-2008). The new technology and its application for papermaking wastewater advanced treatment were introduced at home and abroad, the development and application of magnetic pre-treatment, the enzymatic advanced treatment, biological genetic engineering technique, biomimetic-coagulating technology, photochemical catalytic oxidation and combined process in particular.%目前制浆造纸废水中大部分发色的木素衍生物都难于被降解脱色,排出废水的色度和COD较高.因此,必须对制浆造纸废水进行深度处理,进一步降低出水的COD和色度,提高出水质量,以达到《制浆造纸工业水污染物排放标准》(GB3544-2008)的排放要求.文章着重介绍了国内外制浆造纸废水深度处理的最新技术,尤其对磁化预处理技术、生物酶深度处理技术、生物基因工程技术、复合仿生物酶技术、新型光催化氧化技术和组合技术的研发与应用进展进行了总结和分析.
