摘要
水杨酸甲酯废水及水杨酰胺废水有机物浓度高、难以直接生物降解。采用“树脂吸附—吹脱—UASB—A/O”组合工艺处理该类废水,实际运行结果表明,出水水质能达到GB 8978—1996《污水综合排放标准》中第二类污染物的三级标准,运行经济可靠且能回收水杨酸甲酯及水杨酰胺。
Methyl salicylate wastewater and salicylamide wastewater with high organic concentrations are difficult to be directly biodegraded.The combined process of resin adsorption-air stripping-UASB-A/O is used to treat this type of wastewater.The actual operation results show that:the effluent quality can reach the third level standard of GB 8978-1996 for classⅡpollutants;the operation is economical and reliable,and the methyl salicylate and the salicylamide can be recovered.
