The treating method for methyl salicylate producing waste water was studied. The resin complexing-adsorbing process was selected to remove the high concentrated salicylic acid and methyl salicylate. Dynamic adsorption through resin column was investigated. The quantity of effluent became worse as treating volume increasing. Considering the treating effect and the investigation of the project, the adsorption rate of 1.5 BV/h was selected and the treating volume of 10 BV was better when HW as the first-stage resin. However the second-stage resin of HW99 showed a less removal ratio, which was near 55% for COD and was up to 87% for salicylic acid. The removal ratio of COD was only 25% and less than 44% for salicylic acid. Through the treating process, the removal ratio for COD and salicylic acid were more than 90% and 92% , respectively.%水杨酸甲脂生产废水采用HW络合吸附树脂进行一级吸附处理时,COD和有机物的去除率随着处理量的 增大迅速降低,综合考虑,选用1.5 BV/h为最佳吸附流速,处理量为10 BV.二级HW99吸附树脂的处理效果较差,COD去除率小于55％,水杨酸的去除率大于87％.经过本工艺处理后,COD以及水杨酸的去除率分别达到90％和92％.
