| 摘 要： | 以亚甲蓝水溶液做模拟印染废水，采用Fenton试剂氧化法对其进行处理，以水样吸光度作为评价指标，利用单因素优化及正交实验法，对Fenton试剂用量、反应时间和入水pH进行了系统的研究．实验结果表明，Fenton试剂氧化脱除模拟印染废水色度的效果明显，水样脱色率达到99％以上；随着Fenton试剂用量的增加以及反应时间的延长，水样色度去除率提高，适宜的Fenton试剂用量及反应时间分别为5mL试剂／25mL水样、30min；入水pH存在适宜值4，在入水pH由4降低N3和由4升高到6的过程中，水样色度去除呈现降低的趋势；Fenton试剂氧化模拟印染废水中，3因素影响大小顺序为：反应时间〉Fenton试剂用量〉入水pH．

| Abstract: | Methylene Blue watery solution was selected as printing and dyeing simulant wastewater, then it was disposed by Fenton oxidation technology,and the color removal rate was selected as evaluated index.By the methods of single factor analysis and orthogonal tests,the Fenton reagent dosage,reaction time and initial pH was researched by the numbers.The experiments results showed that the color removal rates of water sample increased with the increase of Fenton reagent dosages and with the extendity of reaction t... |
