  • 摘要: 为了对PVA(聚乙烯醇)溶液中PVA去除进行研究,采用UV/Fenton氧化技术氧化处理PVA溶液。探究了UV/Fenton氧化PVA溶液的影响因素,主要研究了反应时间、初始pH、H2O2/COD和H2O2/Fe2+,获得了各个因素对PVA溶液COD去除率的影响规律以及PVA溶液经处理后的B/C(BOD5/COD)变化规律。实验表明,随着H2O2/COD投加比的增加,COD去除率不断增加,B/C呈现先增加后减少的现象;随初始pH的增加,COD去除率以及B/C均呈现先增加后减少的现象;随着H2O2/Fe2+不断增加,COD去除率以及B/C均呈现先增加后减少的现象;随反应时间的增加,COD去除率以及B/C均增加之后趋于稳定。当H2O2/COD=1.5,pH=4,H2O2/Fe2+物质的量之比为10,T=30 min时COD去除率效果比较好,经过处理之后溶液的 B/C由0.1 增至0.6,可生化性提高,为后续生物处理创造条件。
    Abstract: In order to conduct deep research into the removal of the PVA in the water,the UV/Fenton oxidation was used to treat the PVA wastewater.This research explored the impact factors of UV/Fenton oxidation on PVA wastewater,and mainly studied the reaction time,the initial pH,the H2O2/COD value and the H2O2/Fe2+ value,thus obtaining the impact pattern of these factors on the COD removal as well as the variation pattern of B/C.The experiments showed that with the increase of the H2O2/COD value,the COD removal rate rose and the B/C value increased firstly and deceased afterwards.With the increase of the initial pH value,the COD removal rate and the B/C value rose initially while dropped afterwards.With the increasing H2O2/Fe2 +value,the COD removal rate and the B/C value acted similarly:increased firstly and declined afterwards.The COD removal rate and B/C increased over reaction time,until a steady status was achieved.Under conditions of T=30min,H2O2/COD=1.5,pH=4 and H2O2/Fe2+=10,a desirable COD removal effect could be witnessed,and the B/C value increased from 0.1 to 0.6,which created conditions for the following biological treatment.
