Title Electric Biological Reactor for Degradation of Nitrochlorobenzene Containing Wastewater
Abstract This paper describes the sources and characteristics of nitrochlorobenzene wastewater，and summarizes existing nitrochlorobenzene wastewater treatment technology. Via controling of reactor parameters such as the applied electric field voltage, to explore the optimal operation conditions. By using UV spectrum, liquid chromatography, mass spectrometry and other detection methods, analysising of the intermediate products and combining with references, to infer the mechanism of anaerobic degradation of nitrochlorobenzene. Advanced of the technology was evaluated by means of analysising the toxicity of yielding water. It was founded that electric field environment favored the reduction and dechlorination of the degradation. The acute toxicity test showed that notri chloro compunds are converted into amino compounds after the treatment of UASB or BES-UASB, and the structure of target pollutants changes and the toxicity of the raw water decreases greatly. The results of experiment indicated that electric bioreactor responses to nitrochlorobenzene wastewater could achieved a result with ideal degradation and biological treatability improvement.
