| 摘 要： | 为研究投菌法用于焦化废水降解的效果，从武钢焦化厂活性污泥中分离筛选出8个能以萘或吡啶为惟一碳源的优势菌株，对其进行了分类学鉴定和脱氢酶、多酚氧化酶活性测定，试验了它们对焦化废水的降解效果。结果是CN3，CN4和DB2对焦化废水的降解率分别33．6％，32．3％和26．4％；在活性污泥中投加优势菌株后，降解率分别达到51．8％，49．1％和38．6％，与普通活性污泥法相比，降解率提高了16．3％，13．6％和3．3％。研究表明，应用投菌法有利于提高焦化废水的降解率。

| Abstract: | A study of bacteria-throwing on coke-plant wastewater with destination of effective degradation to it. From activated sludge in Wugang Coke-Plant, eight strains existing in naphthalene or pyridine were separated and identified. Their dehydrogenase and polyphenol oxidase activities were tested. Degradation values of the 8 pure preponderant strains to coke-plant wastewater are different. CN3 ,CN4 and DB2 have higher degradation values than others as 33.6%,32.3% and 26.4% respectively. Reformative sludge in which CN3,CN4 and DB2 were added separately has an improved degradation value as high as 51.8%, 49.1% and 38.6%. It's 16.3%, 13.6% and 3.3% higher than ordinary activated sludge. |
