摘要:
为进一步改善制糖污水的治理方法，从制糖废水的活性污泥中分离出一株具有好氧反硝化作用的细菌，研究了不同pH、温度和C/N比对其反硝化速率的影响。结果表明：分离出的菌株为球形菌，革兰氏染色为阳性，菌落颜色为土黄色，结合生理生化等特性，鉴定为海球菌属（Marinococcus sp.）。该菌株反硝化反应的最适宜pH7.5、温度为35℃左右，反硝化速率可达到75%；菌株最适C/N为6，其反硝化速率可达到85%。
Abstract:
In order to further improve sewage disposal method,an aerobic denitrification strain was isolated from active sludge of wastewater pool of sugar manufacturing,the effect of pH,temperature and C/N on the denitrification rate of this strain was analyzed.The results showed that this strain was spherical bacteria,Gram positive and colony with yellow.According to the morphological and physiological biochemical characteristic,this strain was identified as Marinococcus?sp..The optimum pH of denitrification was 7.5 and the optimum temperature was about 35℃,denitrification rate of strain was more than 85% under this condition.The optimum C/N was 6,and denitrification rate of strain was more than 85%.?
