  • 摘要: 为了研究水解酸化工艺处理印染废水机理及其必要性,尝试用分子量及其分布和聚乙烯醇(PVA)降解程度作为论证指标,并综合后续好氧生物处理。提出以VFA产生和pH显著下降作为印染废水水解酸化的评判标准是不适用的;印染废水水解酸化的作用主要在水解阶段,COD虽没有明显降低,但分子量和PVA随着反应过程有显著下降;印染废水水解酸化可以大大降低好氧生物处理的难度,经过水解酸化的印染废水比未经水解酸化的印染废水好氧生物处理后COD去除率高40.2%,分子量下降率高66.2%。
    Abstract: In order to study the mechanism of the treatment of printing and dyeing wastewater by hydrolysis and acidification process, combined with the subsequent aerobic biological treatment, molecular weight and its distribution and degree of polyviny alcohol (PVA) degradation were used as evaluation indexes.It's not applicable to use the generation of VFA and the significant decline of pH as judgment criteria.The main function of printing and dyeing wastewater hydrolysis and acidification was in the stage of hydrolysis.COD was not significantly reduced, but the Mw and PVA with the reaction process dropped remarkably.Printing and dyeing wastewater hydrolysis and acidification can reduce the difficulty of the aerobic biological treatment immensely.In contrast with the raw wastewater, the COD and Mw removal rates of the printing and dyeing wastewater after hydrolysis and acidification through aerobic biological treatment were higher 40.2% and 66.2%, respectively.
