焦化废水具有水量大、难降解、水质复杂和处理成本高等特点，且随着“两山论”、“零排放”和GB 16171—2012《炼焦化学工业污染物排放标准》等新理念、新标准的提出，传统深度处理技术已难以使焦化废水处理达标；为了使焦化废水稳定达标排放，探讨了以非均相臭氧催化氧化技术、磁混凝技术和聚瓷膜分离技术为核心的单元深度处理新技术及其分别耦合深度处理新技术；分析了新型臭氧催化剂和新型臭氧反应设备、新型重介质、新型膜材料和新型膜结构分别作为非均相臭氧催化氧化技术、磁混凝技术和聚瓷膜分离技术的重要特征；介绍了3种单元新型深度处理技术及其分别耦合技术的应用现状，并指出耦合新型处理技术可以使焦化废水处理后稳定达到废水排放标准或废水回用标准，总结了不同技术的绿色环保、处理成本低、矿化程度高、处理效果好、短流程和运行稳定等技术优势。根据单元深度处理新技术及其分别耦合新技术的特点，形成了完善和成熟的集成技术工艺包，这将是今后焦化废水深度处理新技术发展的新趋势。

Coking wastewater has the characteristics of large quantity, difficult degradation, complex water quality and high treatment cost. With the proposal of new concepts and standards such as two mountains theory,zero emission and GB 16171—2012 emission standard of pollutants for coking chemical industry, it is difficult for traditional advanced treatment technology to make coking wastewater meet the standard. In order to make coking wastewater discharge stably up to standard, the new technology of advanced unit treatment and the new technology of coupling advanced treatment are discussed in this paper, which are based on heterogeneous ozone catalytic oxidation technology, magnetic coagulation technology and poly-ceramic membrane separation technology. The paper analyzes the important characteristics of new ozone catalyst and new ozone reaction equipment, new heavy medium, new membrane material and new membrane structure as heterogeneous ozone catalytic oxidation technology, magnetic coagulation technology and poly-ceramic membrane separation technology respectively. The application status of these three new advanced processing technologies and their coupling technologies are introduced. It is pointed out that the coupling new treatment technology can make the coking wastewater meet the wastewater discharge standard or wastewater reuse standard. The author summarizes the advantages of these technologies, such as green environmental protection, low treatment cost, high degree of mineralization, good treatment effect, short process and stable operation. According to the characteristics of new unit advanced treatment technologies and its coupling technologies, forming a perfect and mature integrated technology package will be the new trend of the development of coking wastewater advanced treatment technology in the future.
