DA-201树脂回收、净化废水中苯酚的研究

Experimental Research of Using DA-201 Resin to Recover Phenol from Industrial Wastewater

作者研究了 DA- 2 0 1吸附树脂回收、净化废水中的苯酚的工艺条件 .实验表明 :当废水的 p H<7时 ,吸附树脂不仅能回收苯酚 ,而且不产生二次污染 ,失效树脂使用 5 %的 Na OH溶液或甲醇脱酚 ,其效率接近 10 0 % .

This paper mainly deals with experimental conditions and results about recovering phenol from wastewater by using DA 201 as the resin. It is shown that DA 201 can efficiently recover phenol from the wastewater and does not bring about secondary pollution when the pH of the wastewater is lower than 7. And when the resin ceases to be effective, it is easily desorbed with the solution of 5% NaOH or methanol with the desorbing rate being close to 100%.
