1、基于Fenton氧化的工业有毒废水预处理技术研究4)采用呼吸速率试验与SBR工艺模拟生化处理试验两种方法,对经预处理废水毒性的降解效果进行检测,结果表明含甲酸钠废水经电.Fenton氧化预处理后,毒性污染物得到减少,对生化处理系统的冲击得到显著降低。电一Fenton氧化是适宜于该类有毒废水的预处理的一个有效方法。基于以上研究成果,本文最后对Fenton氧化技术的深入探索及研究方向给出了建议。本研究采用Fenton工艺对工业有毒废水进行预处理的试验研究。通过系统的调查分析和试验研究,探讨了Fenton氧化技术对于该类有毒工业废水或废水中有毒有害污染
2、物质的处理效果及影响因素,从而可以为有毒工业废水预处理措施的实施提供理论依据,为该技术的深入研究和工程化推广应用提供技术参考。关键词:Fenton氧化,毒性,工业废水,预处理Ⅱ江苏大学硕士学位论文ABST队CTWiththerapiddevelopmentofindustry,alotoftoxicwastewaterhavebecomeamajordifficultyfortheindustrialwatertreatmenttechnologyresearching.Toxicwastewatercannotbedirectlytreated
