摘 要:采用Fenton氧化絮凝-吸附-蒸馏的组合工艺处理灭多威废水,实现了废水的无害化处理及循环套用。考察了组合工艺中Fenton反应优化条件,如投加量、反应初始pH值等,以及不同种类吸附剂的处理效果,处理后废水的循环套用的可行性。结果表明,Fenton试剂氧化处理灭多威废水效果明显,COD去除率达到95%以上,废水颜色由深黄色变为无色。Fenton试剂的优化投加量和反应条件:pH=4、双氧水投料为30 g/L、七水硫酸铁投料量8 g/L。吸附剂为活性炭,投料3 g/L。经处理后的灭多威废水蒸馏后所得的回收物和蒸馏废水均可套用。 |

Abstract:The techniques of Fenton oxidation,flocculation,adsorption and distillation were combined for the treatment of methomyl wastewater. The removal rate of COD was above 95%,and the water thus obtained was colorless and available for recycle use. The effects of different adsorbents and the conditions of Fenton reaction such as the dosage of the Fenton reagent and the primary pH value of the water were investigated and optimized. |
