【摘要】：以没食子酸加工废水生化出水为研究对象,以色度和COD去除率为参考指标,研究了Fenton氧化、活性炭吸附、臭氧氧化、聚合硫酸铁-聚丙烯酰胺和聚合氯化铝-聚丙烯酰胺复合絮凝的处理效果并进行了经济可行性分析。结果表明,除臭氧氧化外,其他处理方法出水色度和COD均分别低于50和100 mg/L;Fenton氧化法的药剂成本最低,但存在流程较长,且出水p H较低,还需调节p H等缺陷,运行成本高;在达到同样的出水色度和COD情况下,聚合氯化铝-聚丙烯酰胺絮凝经济效益最佳。
[Abstract]:The oxidation of Fenton, adsorption of activated carbon and ozone oxidation were studied by taking the biochemical effluent from Gallic acid processing wastewater as the research object and the chromaticity and COD removal efficiency as the reference index. The treatment effect of polyferric sulfate polyacrylamide and polyaluminium chloride polyacrylamide composite flocculation was analyzed and the economic feasibility was analyzed. The results showed that, in addition to ozone oxidation, The effluent chromaticity and COD of other treatment methods are lower than 50 mg / L and 100 mg / L Fenton oxidation process respectively, but the process is longer, the effluent pH is lower, the defects of pH and so on need to be adjusted, and the running cost is high. Under the same chroma of effluent and COD, the flocculation efficiency of polyaluminium chloride and polyacrylamide is the best.
