摘 要:将树脂吸附工艺、催化湿法氧化工艺、臭氧氧化工艺和蒸发浓缩工艺有机结合,实现次磺酰胺类促进剂高盐高化学需氧量(COD)生产废水100%资源化处理。生产废水处理步骤如下:生产废水经树脂吸附回收有机胺类原料,通过催化湿法氧化+臭氧氧化两级氧化减小COD,再通过多级树脂吸附去除重金属离子、钙离子和镁离子等后进行蒸发浓缩,所得处理水满足离子膜烧碱一级进水标准,实现促进剂生产废水的零排放。In this work,100%resource utilization of high salt and high chemical oxygen demand(COD)wastewater from hyposulfonamide accelerator production was achieved by organically combining the resin adsorption process,catalytic wet oxidation process,ozone oxidation process and evaporation concentration process.The wastewater treatment steps were as follows:Organic amine raw materials in the production wastewater were absorbed and recovered by resin adsorption,COD was reduced by catalytic wet oxidation and ozone oxidation,then the heavy metal ions,calcium ion and magnesium ion were removed by multi-stage resin adsorption,and at the last step,evaporation concentration was carried out.The obtained treated water met the primary influent standard of ion-exchange membrane caustic soda.With this process,zero emission of wastewater from accelerator production was realized.
