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。
The advanced treatment of gallic acid processing wastewater was carried out in this paper,with the chroma and COD removal efficiencies as reference index.The Fenton oxidation, activated carbon adsorption, ozone oxidation, polymerization iron sulfate（PFS）-polyacrylamide（PAM） and poly aluminum chloride flocculation （PAC）-PAM were carried out, and the economy was analyzed. The results showed that, the effluent chroma and COD were lower than 50 and 100 mg/L by above technologies except the ozone oxidation. Thecost of agents inthe Fenton oxidation was the least, but theprocess was long, and the effluent pH was low which need to adjust after reaction, and had high operating costs. The economic benefit of the flocculation with polymerization aluminum chloride was the best when the effluent chroma and COD was at the same level.
