| 摘 要： | 采用混凝-沉淀法对VAE乳液废水进行预处理,比较了FeCl_3和聚合硫酸铁(SPFS)混凝对浊度及COD指标的去除效果,重点考察了pH值变化对FeCl_3混凝效果的影响以及不同助凝剂对FeCl_3的助凝效能.结果表明,FeCl_3对VAE乳液废水的混凝效果明显好于SPFS,其最佳混凝pH值为7～9;阳离子型PAM CZ4060对FeCl_3有明显的助凝效果. |
| 关 键 词： | FeCl_3 阳离子型PAM 浊度 COD 混凝-沉淀 VAE乳液废水 |

| Abstract: | Coagulation-sedimentation process was used for VAE emulsion wastewater pretreatment.Turbidity and COD removal efficiency by FeCl_3 and poly-ferric sulfate(SPFS)were compared.Influence of pH value on coagulation effect of FeCl_3 and coagulation aid efficiency of different coagulant aids were investigated to achieve more effective pretreatment method of the VAE emulsion wastewater.Results indicate that coagulation effect of FeCl_3 is better than that of SPFS.Optimum rang of pH value is 7-9.Coagulation aid eff... |
