印染污泥中多环芳烃（PAHs）等POPs大量存在，导致其处理处置过程二次污染严重。基于源头消减策略，提出采用超声(US)-芬顿（Fenton）联合技术原位降解其中PAHs。参照实际印染污泥中PAHs的含量，构建印染污泥模拟体系，以模拟印染污泥及真实印染污泥对研究对象，采用超声-芬顿联合技术作为深度处理技术，重点研究不同环境介质及条件下，影响PAHs降解的关键微环境因素，阐明US-Fenton降解印染污泥PAHs的协同作用机制，揭示PAHs主要组分之间、PAHs与其他有机质之间的竞争机制，通过生物毒性实验评估US-Fenton技术对印染污泥中的PAHs消减效果。利用现代分析测试技术对其降解产物进行鉴定，并结合量子化学计算，从分子角度探究PAHs的降解途径、中间产物及过程机制。从而提出PAHs的原位降解机理，优化调控其降解效率，推动深度氧化技术在污泥中POPs降解的基础理论和技术发展。

Large quantities of persistent organic pollutants (POPs), for example polycyclic aromatic hydrocarbons (PAHs) contained in Textile dyeing sludge, will result in the secondary pollution in the process of treatment and disposal of this solid waste. In this study, baseed on the source reduction strategy, a combined ultrasound with Fenton (US-Fenton) technology successfully employed to degrade PAHs in textile dyeing sludge. Real textile dyeing sludge and simulated textile dyeing sludge (containing PAHs and without PAHs) were prepared to subject to the degradation experiments of US-Fenton oxidation. The key environmental influence factors, the synergistic mechanism and the competitive mechanism between different PAHs and PAHs as well as organic matter will be considered using the modern analysis determination techniques. The toxicity test will be conducted to assess the detoxification possibility of the textile dyeing sludge after the treatment of US-Fenton process. The quantum chemical calculation was also conducted to facilitate the identification and confirmation of degrading intermediate products and predict potential initial attack sites during the AOPs degradation of PAHs. Finally, an optimal detoxification scheme of PAHs degradation with US-Fenton combined technology in textile dyeing sludge could be provided. This successful accomplishment of this project will offer some sueful suggestion for the technological development for the degradation of POPs in sludge.
