中文摘要:

      大量的脱墨污泥是目前废纸制浆企业面临的重要环境问题之一。脱墨污泥的合理资源化利用是解决当前困境的有效途径。本文分析了脱墨污泥的基本性质，包括不同废纸制浆脱墨污泥的主要成分、金属离子含量和有机污染物等；基于近几年国内外的相关研究成果，综述了脱墨污泥资源化利用在生物炭、生物油、回收有机物和无机物、堆肥与厌氧消化、营养基和生物复合材料等方面的最新研究进展和应用前景。

Abstract:

      The producing of huge amount of deinking sludge is currently one of the important environmental problems faced by waste paper mills. The reasonable utilization of deinking sludge is an effective way to solve the current contradictions. The basic properties of deinking sludge， including the main components， metal ion content， and organic pollutants of deinking sludge produced from different pulping process using waste paper as raw material were summarized. Based on the relative research findings at home and abroad， the latest research progress and application prospect of resource utilization for deinking sludge in biochar， bio-oil， organic and inorganic substance recovery， composting and anaerobic digestion， nutrition substrate and biocomposite materials were reviewed as well.
