吸附—催化氧化法处理造纸黑液

THE TREATMENT OF BLACK LIQUOR FROM MAKINGPAPAR BY ABSORPTION-CATALYTIC OXIDATION

本文研究了以活性炭为吸附剂和催化剂,空气为氧化剂,吸附催化氧化处理造纸废水中有机污染物的可能性。并对反应温度,反应时间及PH值等影响废水处理效率的因素进行了探讨。在活性炭用量一定、温度稍高,PH值较低等条件下,该法COD去除率达89％以上,同时还进行了静态吸附对照试验。

This paper studies the possibility ont reating black liguior of paper-making by absorption-catalytic oxidation.Inthis paper, active carbonis used as absorbent and catalyst, air is used as oxidant The factors which affact the efficiency of treating waste water, e. g. , reaction temperature, reactbon time and PH, are discussed. Under the suitable conditions, the reduction of COD is more than 89%. The comdarative static absorption experiments are also done.
