摘　　要：研究了采用Fenton法对难以生物降解处理的松香加工废水进行预处理的方法及影响因素。结果表明,最佳运行条件为初始pH=3,n(H_2O_2)/n(Fe^(2+))=3︰1,m(H_2O_2)/m(COD_(cr))=10︰1,反应时间30 min。经Fenton法处理后,当pH=3,V(H_2O_2)=0.90 mL,m(FeSO_4·7H_2O)=0.8181 g,出水CODcr为20.5 mg/L,COD_(cr)去除率达到94.86%,Fenton法是深度处理松香加工废水的一种有效工艺,同时表明Fenton试剂对松香加工废水中的有机物有明显的降解作。The methods and influencing factors of pretreatment of rosin processing wastewater with difficulty in biodegradation were studied by Fenton method. The result showed that the optimum operating conditions about the initial pH was 3, the proportion of mass ratio between hydrogen peroxide and ferrous ion was 3 ： 1, the tool proportion of H202/CODCr was 10 ： 1 and 30 minutes fur reacting was the proper choice. The appropriate dosage between FeSO4·7H2O and H2O2 was 0.8181 gram and 0.9 milliliters. In that case, a CODCr＇s removal rate could reach tip to 94.86 %. Thus, Fenton is a kind of effective depth of colophony wastewater treatmenl process. In the meanwhile; Fenton reagent has a striking effect on degradation of organic compounds in wastewater of rosin.
