摘要
本文对松脂加工废水中的挥发物和非挥发物组分进行分析,探索了符合排放标准的松脂加工废水的处理方法。从松脂废水中回收的挥发物占废水总量的3.25%,主要有α-松油醇、乙酸松油酯、乙酸异胡薄荷醇酯、1-松油醇等;非挥发物占废水总量的3.8%,主要有枞酸、长叶松酸等松脂酸等。处理后的固体废弃物晒干后可作为燃料,废水可达到排放标准。
The volatile and non-volatile components in rosin processing wastewater were analyzed,and the treatment methods of rosin processing wastewater meeting the discharge standards were explored.The volatiles recovered from rosin wastewater accounted for 3.25%of the total wastewater,mainly includedα-terpineol,terpineol acetate,isomenthol acetate,1-terpineol,etc.Non-volatile substances accounted for 3.8%of total wastewater,mainly abietic acid,folic acid and other oleic acids.The treated solid waste could be used as fuel after drying,and the wastewater met the discharge standard.
