摘要
研究了硫酸、Fenton试剂对酚的催化降解作用，证实了硫酸与Fenton试剂对酚的催化降解具有协同作用。H_2SO_4－Fenton试剂对高浓度含酚废水的处理结果说明，在Fenton试剂中加入硫酸可大大增加其对酚的降解能力。与单独的Fenton试剂法比较，当H_2O_2∶COD（重量比）＜0．8时，本法对COD≥14000mg／L含酚废水COD去除率可提高40％以上，对高浓度含酚废水具有很好的处理效果。
The catalysis of Fenton reagent and sulfuric acid (H_2SO_4+Fenton)to degradation of phenol was studied.The existence of synergistic effect in H_2SO_4-Fenton system was verified. The experiments of highly concentreated phenol wastewater degradation by H_2SO_4+Fenton reagent were carried out. The results indicated that the degradation effect of Fenton reagent was greatly improved by the introduction of H_2SO_4 Compored with Fenton reagent,while H_2O_2:COD(weight ratio)is less than 0.8 and COD in is phenol wastewater content more than 14000mg/L, the removal of COD by the treatment process is over forty percents more than Fenton's.H_2SO_4-Fenton reagent can be used to remove highly concentrated phenol in wastewater.
