Fenton氧化工艺及对COD去除率的影响

Fenton Oxidation Process and Its Effect on COD Removal Rate

在造纸废水处理中采用的Fenton高级氧化方法,主要是利用Fenton试剂可以在较短时间内将造纸废水内较难降解的有机物氧化分解,具有较高氧化率,而且不会产生二次污染的特点。在重点分析Fenton氧化反应原理、主要反应条件以及对COD去除率的影响的基础上,通过实验对比寻找了最优Fenton氧化工艺条件。同时,介绍几个纸厂的Fenton系统运行情况。

The Fenton advanced oxidation method used in the treatment of papermaking wastewater mainly uses Fenton reagent to oxidize and decompose the refractory organic matter in papermaking wastewater in a relatively short time, which has the characteristics of high oxidation rate and no secondary pollution. On the basis of emphatically analyzing Fenton reaction principle, main Fenton reaction conditions and their effects on COD removal rate, the optimal Fenton process conditions were found through experimental comparison. At the same time, the running examples of Fenton system in several paper mills are introduced.
