摘　　要：醋酸乙烯-乙烯共聚乳液(VAE乳液)是一种重要的化工产品,在生产过程中会产生大量VAE乳液废水。通过设计絮凝沉淀的实验方法,处理VAE乳液生产废水,探讨得出最佳絮凝沉淀的工艺条件。结果表明:经过硫酸亚铁破乳后,再调节最佳pH值至9~10,进行混凝沉淀处理,悬浮物的去除率可达80%以上。Vinyl acetate-ethylene copolymer emulsion(VAE emulsion)is an important chemical product,and a large amount of VAE emulsion wastewater will be generated during the production process.Designing the experimental meth⁃od of flocculation and sedimentation to treat the VAE emulsion wastewater,and discussing the best flocculation and sedi⁃mentation process.The results showed that:while the ferrous sulfate is demulsified and the pH is adjusted to 9~10,the removal rate of suspended solids could reach more than 80%after the coagulation precipitation treatment being carried out.
