Abstract

Abstract:

　 The capacity of oil is increased fixed other conditions to form the impact on the activated sludge system when the star ting sludge mass concentration are 1 .5 ×10³ , 2 .0 ×10³ , 2 .5 ×10³ mg/ L.When the oil mass concentration is 10 mg/L , the impact on the performance of activated sludge is faint .When it is 15 mg/ L, the activated sludge system is impacted in a degree , but the performance of activated sludge is not changed greatly and the system can circulate normally .The activated sludge system is impacted obviously w hen the oil mass concentration is 20 mg/ L.When it is 30 mg/ L , the activated sludge system is impacted obviously and continuous circulating can' t be recovered .Meanwhile , the evolvement process of microorganism species was observed.

摘要： 在污泥起始质量浓度分别为1.5×10³ , 2.0×10³, 2 .5×10³ mg/ L 时增大油负荷(其它条件保持不变)来形成对活性污泥系统的冲击。油的质量浓度低于10 mg/ L 时, 对活性污泥性能的冲击很小;油的质量浓度为15mg/ L 时, 有一定的冲击, 但是活性污泥的性能没有大的改变, 系统运转正常;油的质量浓度为20 mg/ L 时, 有明显的冲击;油的质量浓度达到30 mg/ L 时, 有巨大的冲击作用, 连续运行无法恢复。同时, 观察了油的冲击下微生物相的演变过程。
