投菌强化氧化沟法处理采油废水

Oxidation Ditch Enhanced by Special Bacteria for Treating Petroleum Wastewater

为了获得较高的采油废水处理效率,针对采油废水的水质特点,通过实验筛选出了专用菌种。分别采用氧化沟法和投菌强化氧化沟法进行了采油废水处理的对比实验。结果表明:该专用菌种有很强的降解能力。投菌后,氧化沟的处理效率大幅度提高,出水COD值降低,并增强了抗冲击负荷的能力。从而证明了该方法的有效性。

To obtain higher efficiency of the petroleum wastewater treatment,the special bacteria to enhance its treatment were sifted through experiments according to the quality of petroleum wastewater. The comparative experiments between oxidation ditch and oxidation ditch enhanced by special bacteria were performed for treating the petroleum wastewater. The results show that the special bacteria are characterized by rapid degradation. After the special bacteria are added, the treatment efficiency of the oxidation ditch is significantly increased, the COD value of the treated wastewater decreased, and the ability against shock loadings is enhanced,proving the effectiveness of the proposed approach.
