中文摘要： 针对炼化污水有机物成分复杂、可生化性差的关键科学问题，为应对提标改造和节能减排的国家重大需求，本课题提出“源头氧化减排、生化过程强化、深度精制处理”的研究思路，实现污水的高效、深度脱碳除氮。对炼化废水中难降解特征污染物（含硫/氮有机物）赋存形态及浓度水平的理论模型预测和浓度测定，通过设计三维电极材料构建高级氧化新工艺实现难降解有机物的高效低耗去除，采用高级氧化-生化耦合新方法对污水进行深度处理，实现炼化污水的达标排放和回用。揭示炼化废水中典型难降解污染在物化-生化强化-后物化/生化深度处理工艺中的交互作用、转化途径，确定污染物结构、模型框架与处理效率间的定量关系，通过研究成果的部分工程应用，为我国炼化污水深度处理提供重要的理论参考及主导性技术。

英文摘要： In order to solve the key issues of the refinery and petrochemical wastewater, including the complex compositions of organic compounds and poor biodegradability, with the goal of meeting the demand of upgrading-reconstruction, energy conservation and emission reduction of our country, this project proposes that an new idea of “emission reduction by sources oxidation, biodegradation intensification, deep and accurate treatment” and achieve the efficient treatment accompanied by the deep decarbonization and denitrification. By measuring and theoretically modal predicting the concentrations and forms of the typical refractory organic pollutants (N and S containing compounds), efficient removal of refractory organic pollutants with low energy cost by constructing the new advanced oxidation processes (AOPs) through developing three dimensional electrodes, the refinery and petrochemical wastewater will be deep treated, discharged with reaching the standards and reused by using the integrated AOPs-biodegradation process. We will reveal the interactions, degradation paths of the typical refractory organic pollutants and their quantity relationships between structure of pollutants, model frame and treatment efficiencies in the physicochemical- biodegradation intensification-post physicochemical/biodgradation deep treatment, and apply part of achievements to industrial application to provide important theory and key technologies for the refinery and petrochemical wastewater in our country.
