Abstract :
To study the treatment of the slaughter wastewater treatment, application of ABR/contact oxidation process of a lab scale was carried out, taking pig excrement as the inoculation source. Research results showed that COD removal rate lied from 72.2 ~ 94.8% of the entire process, and the anaerobic VFA levels were lower than 400 mg/Lo when the water quality fluctuated, the outflow remained stable, which showed a strong impact resistance. By scanning electron microscope, it had been observed that anaerobic reactor with baffle can cultivate granular sludge .its shape and the main species are closely related with its growth environment, 1st to 3rd of anaerobic sludge were mainly composed of spherical and ellipsoid gradually changes for filamentous bacteria.
