摘　　要：焦化废水,废水排水质成分复杂且有害。除了氨氮、氰、硫氰根等无机污染物外,还含有酚、油类,萘、吡啶、蒽等杂环及多环芳香族化合物(PAHs)等难于降解且易致癌的物质。不处理排放,不仅会对环境造成严重污染,同时也直接威胁到人类的健康。本文从焦化废水的产生、组成、水质等方面进行了现状阐述,对焦化废水现有的处理技术做了简要分析,针对现有处理技术的不足,提出了焦化废水新的膜处理焦化废水。The coking wastewater which processes by coking and gasification has many malpractices, such as a large emissions and the composition of wastewater is very complex which has a lot of inorganic contaminants like ammonia nitrogen, cyanogens, sulfur cyanogens root . Besides, it also contains heterocyclic and polycyclic aromatic compounds （PAHs） such as phenol oils, naphthalene, pyridine and anthraquinone, which is very difficult to diminish and it is carcinogenic. It will not only cause serious environmental pollution, but also directly threat the health of human beings, if the wastewater discharges without any processing. This article from the coking wastewater generation, composition, water quality and other aspects of the status quo, existing treatment technology for coking waste water to do a brief analysis, in view of the existing processing technology, put forward new film coking waste water in coking wastewater treatment.
