Abstract Acylonitrile is an important, highly-useful industrial chemical. And the annual production of acrylonitrile is over 5,000,000 tons. Meanwhile, the same quantity or even more wastewater is generated during production. Several chemical methods may be available in lab-scale. But the harsh reaction conditions and high operational cost have often made these methods not a desirable choice. In this study, oxidation and adsorption is used for deep treatment of acylonitrile wastewater. The results obtained show a decrease of the organic matters after oxidation-adsorption process. However, the oxidation process generally increased effluent color. The removal of color is found only when an adsorption step is performed in coupling oxidation process.Keywords : acrylonitrile; wastewater; oxidation; adsorption Acknowledgements The authors greatly appreciate the financial supports of the National High Technology Research and Development Program of China (No. 2012AA03A607), the National Natural Science Foundation of China (21176135), and the Special funds for technological development research of Research Institutes and Universities from National Ministry of Science and Technology (2013EG111129).
