摘要 制浆造纸废水是重要的环境污染物之一,其中尤以制浆废液污染最为严重。木质素是制浆废液的主要成分,也是木材的主要成分之一,是一种重要的植物资源。半导体多相光催化氧化技术是当前世界水处理研究中最为活跃的领域之一,具有反应条件温和、速度快、效率高、工艺简单洁净、无二次污染等优点。文章简要地叙述了制浆废液的治理现状、半导体多相光催化氧化技术在制浆废液治理中的应用、制浆废液资源化的可行性以及木质素降解产物的应用等。 Pulping wastewater is one of the most important industry pollution. Lignin is the most important component of pulping wastewater. Heterogeneous photocatalytic oxidation with metal oxide semiconductor is the technology with mild reaction condition, fast rate, efficiency, simplicity, cleanness, etc. In this paper, an outline is given on process of pulping wastewater, application of heterogeneous photocatlytic oxidation on process of pulping wastewater, feasibility of utilization of pulping wastewater, and utilization of degradative of lignin.
