摘要 化废水是一种典型的难降解的工业有机废水。其中含有大量的有机化合物，如：酚、胺、萘、油、吡啶、喹啉、蒽等杂环及多环芳香族化合物；还含有多种无机污染物，如：氨、氰、氟化物、含硫阴离子等。 本文采用离子色谱法检测废水中的硫酸根离子，采用气相色谱-质谱联用检测废水中的有机物种类和含量，并探索部分污染物的回收利用价值，最后用氧化的方法处理焦化废水，降解其中部分有机污染物，分析氧化处理效果。 焦化废水中有机物含量高，氨氮浓度大 Abstract Coking wastewater was a typical hard-degradable industrial organic wastewater. It contained a large amount of organic compounds, such as phenols, amines, naphthalene, oil, pyridine, quinoline, anthraquinone heterocyclic and polycyclic aromatic compounds; and a variety of inorganic contaminants such as ammonia, cyanide, fluoride, sulfur-containing anions were also included. In this paper, ion chromatography was utilized to detect the sulfate ions in the wastewater, the sodium ions were determined by atomic absorption spectrophotometer, the gas chromatography - mass spectrometry method was made use of to detect the types and contents of the organic compounds in wastewater. The value of the pollutant recycling was also explored. Finally the coking wastewater was treated by oxidation to degrade some of the organic contaminants and the oxidation treatment effect was analyzed. Experimental results show that the coking wastewater was alkaline and the organic content was high. The benzene materials and the aromatic compound materials were main materials.In the coking wastewater, the ammonia concentration and the sulfate concentration were high, the sodium ion concentration was relatively low. The oxidative effects was obvious and the larger dosage of oxidant was used, the better effects was received. The oxidative effects differed with different oxidants. The treatment effects of Oxidant B was better than oxidant A. The results indicated that the treatment effects of synthetic oxidant of coking wastewater was effective.
