Abstract

Coke plant wastewater containing lots of toxic organic pollutants should be treated before being discharged into the environment. It is challenging to treat toxic and refractory compounds using conventional methods. In this study, a UV-Fenton technology was investigated. When the initial COD, NH3-N concentration and SS of wastewater were 5080 mg/L, 329.9 mg/L, and 847.7 mg/L, results showed that the removal rate of COD, NH3-N and SS were 88.0%, 58.4% and 99.2% respectively under the optimal reaction conditions. Under the identified optimal condition, H2O2 concentration is 75 mmol/L, the concentration ratio of H2O2 and Fe2+ is 3:1, and original pH is 4 within 30 min. GC-MS analysis, revealed that organic substances such as indole and quinoline were degraded effectually.
UV-Fenton去除焦化废水中有毒有机污染物的研究
焦化废水中含有大量的有毒有机污染物,在排放到环境中之前必须进行处理。使用传统方法处理有毒和难熔化合物具有挑战性。本研究对UV-Fenton技术进行了研究。当初始COD、NH3-N和SS浓度分别为5080 mg/L、329.9 mg/L和847.7 mg/L时,在最佳反应条件下,COD、NH3-N和SS的去除率分别为88.0%、58.4%和99.2%。在确定的最优条件下,H2O2浓度为75 mmol/L, H2O2与Fe2+的浓度比为3:1,初始pH为4,30 min内可有效降解吲哚和喹啉等有机物。

期刊介绍: The international Journal of Residuals Science & Technology (JRST) is a blind-refereed quarterly devoted to conscientious analysis and commentary regarding significant environmental sciences-oriented research and technical management of residuals in the environment. The journal provides a forum for scientific investigations addressing contamination within environmental media of air, water, soil, and biota and also offers studies exploring source, fate, transport, and ecological effects of environmental contamination.
