摘要
随着工业的发展,水污染问题越来越受到人们的关注。其中含酚废水由于容易在水中积累并转移,对水环境构成极大地威胁。本文采用的电-Fenton法阳极材料为铁片,阴极惰性材料为铜片,降解1g/L的苯酚溶液。实验考察了电流密度、外加H2O2的量、初始苯酚溶液浓度、pH对苯酚降解率和COD去除率的影响。介绍了降解苯酚的主要方法,通过实验确定了实验的最佳条件,在最佳条件下,苯酚去除率高达95%,COD去除率达78%。
With the development of industry, water pollution has attracted more and more attention. Among them, phenolic wastewater is easy to accumulate and transfer in water, which poses a great threat to the water environment. In this paper, the electroFenton method was used to degrade phenol solution of 1 g/L with iron sheet as anode material and copper sheet as cathode inert material.The effects of current density, the amount of added hydrogen peroxide, initial concentration of phenol solution, pH on phenol degradation rate and COD removal rate were investigated. Firstly, the main methods of phenol degradation were introduced. The optimum conditions were determined by experiments. Under the optimum conditions, the removal rate of phenol and COD reached 95% and 78% respectively.
