| 摘 要： | Fenton法是处理难降解有毒有机污染物的一种有效的方法.以棉浆粕黑液为研究对象,讨论了H2O2和FeSO4投加量、pH值、搅拌时间等因素对废水CODCr去除率的影响,将紫外光照引入Fenton试剂能提高废水中有毒有机污染物的降解速度,提高氧化能力 .实验确定了最佳工艺条件:pH=7,FeSO4投加量4 g/L,H2O2投加量为1.13%(V/V),搅拌时间15 min,此时CODCr去除率达到66.96%.

| Abstract: | Fenton method is an effective way to treat organic pollutants that are difficult to decompose.Cotton pulp black liquor is used as the study objective to discuss the effects of some factors on the removal rate of CODCr,such as the quantity of H2O2 and FeSO4,pH value and dispensing time.It is found that the introduction of UV radiation into Fenton reagent can increase the decomposition rate of toxic organic pollutants in wastewater and also facilitate the oxidation process.The removal rate of CODCr can reach 66.96% when the optimum process conditions are determined as follows: pH value=7,the amount of FeSO4 at 4g/L and H2O2 at 1.13%(V/V) and dispensing time at 45 minutes. |
