| 摘 要： | 采用逐渐增加进水COD浓度、减小水力停留时间的方法启动接触氧化反应器，反应器启动34d后，COD的总去除率稳定在88％，邻苯二甲酸和二甲苯的总去除率分别达到75％和78％。沿水流方向，细菌数量随有机物质的减少而逐渐减少。生物膜厚度呈递减趋势．兼氧、好氧段依次出现游泳型鞭毛虫、游泳型纤毛虫、固着型纤毛虫。

| Abstract: | The contact oxidation reactor was started by method of gradually increasing influent COD concn.and decreasing hydraulic retention time.After34 d of reactor starting,the total removal rate of COD was stable at 88% and the total removal rates of phthalic acid and xylene reached 75% and 78% resp..Along water flow direction,the bacterial number was reduced with the decrease of organic matter and the biofilm thickness decreasing trend.Swimming-flagellate,swimming-ciliates and immovable ciliates appeared in order... |
