摘要:
采用光/电Fenton耦合技术处理退浆废水中难生物降解的高分子物质聚乙烯醇(PVA),考察FeSO4·7H2O投加量、H2O2投加量、初始pH、电流强度、反应时间对PVA降解效果的影响。结果表明:光/电Fenton耦合技术处理退浆废水中聚乙烯醇的最佳反应条件为:pH 4,FeSO4·7H2O投加量14.2 mmol/L,H2O2投加量ρ(H2O2)/COD=2.3,恒压电流强度1 A,反应时间120 min。在此条件下,化学耗氧量(COD)去除率达91%; 总有机碳(TOC)去除率达80%; 生化耗氧量(BOD)与COD比值从原水的0.007提高到0.9。
Abstract:
Photo-electro-Fenton oxidation method was used to treat polyvinylalcohol(PVA)in desizing wastewater.The effects of FeSO4·7H2O and H2O2 dosages,initial pH,current intensity and reaction time on degradation were discussed.The optimum conditions of PVA pre-treatment were obtained as follows:the initial pH of solution was 4.0,the molar concentration of FeSO4·7H2O was 14.2 mmol/L,the concentration ratio of H2O2 to chemical oxygen demand(COD)equals 2.3,the constant current intensity was 1 A, and the reaction time was 120 min.Under these conditions,the removal efficiency of COD was more than 91%,the removal efficiency of total organic carbon(TOC)was more than 80% and the ratio of biochemical oxygen demand(BOD)to COD increased from 0.007 to 0.9.
