摘要
采用紫外线强化Fenton试剂法,以苯酚废水为对象,探究了紫外线和药剂投加量对处理效果的影响。结果表明:对于COD为470 mg/L的苯酚原水,在H2O2投加量为2倍理论投加量,FeSO4·7H2O投加量为1.25 mg/L,pH值为3的条件下,反应60 min后COD去除率为83.37%。紫外线对Fenton试剂法有强化作用,在提高去除效果的同时减少药剂的投加量,降低成本。
The ultraviolet enhanced Fenton reagent method was used to treat phenol wastewater,and the influence of ultraviolet and the dosage of reagent on the removal effect were explored.The results showed that for the phenol raw water with COD of 470 mg/L,the COD removal rate could reach 83.37%after 60 min reaction under the conditions of dosing H2O22 times of theoretical dosage,1.25 mg/L FeSO4·7H2O and pH of 3.Ultraviolet could strengthen Fenton reagent method,improve the removal effect as well as reduce the dosage of agent and the cost.
