摘　　要：为减轻高浓度、难降解有机化工生产废水对环境保护造成的压力,研究依据某金属缓蚀剂在工业生产中的废水情况,采用混凝改进工艺来进行复合处理,并通过对混凝沉淀工艺和氧化工艺的设计配比和实验检验,旨在提高其降解能力。结果表明,联合工艺对废水处理下的污染物浓度降低效果明显,重铬酸盐指数的去除率达到了89.41%,且混合工艺处理下的生化需氧量比值达到0.47,分子降解效果远大于单一工艺处理效果。研究提出的复合处理工艺能高效处理甲基苯并三氮唑废水,为化工行业的健康发展和环境保护提供建设性技术手段。In order to alleviate the pressure on environmental protection caused by high concentration and difficult to degrade organic chemical production wastewater,this study adopts a coagulation improvement process for composite treatment based on the wastewater situation of a certain metal corrosion inhibitor in industrial production.Through the design ratio and experimental verification of coagulation precipitation process and oxidation process,the aim is to improve its degradation ability.The results showed that the combined process had a significant effect on reducing the concentration of pollutants in wastewater treatment.The removal rate of dichromate index reached 89.41%,and the biochemical oxygen demand ratio under mixed process treatment reached 0.47.The molecular degradation effect was much greater than that of single process treatment.The proposed composite treatment process can efficiently treat methylbenzotriazole wastewater,providing constructive technical means for the healthy development and environmental protection of the chemical industry.
