Study on the Mechanism of the Bacteria-added Biological Contact Oxidation Process in the Treatment of Wastewater from Jiemycin Production Process

This paper deals with a treatment system in which the" hydrolytic acidifiCation-two singed biological concoct oxidstion-coagulation" process was used to treat a high strength wastewater from the production process of jiemycin. Particularly, it relates to the characteristics, distribution Patterns and degradetive functions of its aerobic microbial films. The selection and breeding of efficiently degradstive bacteria, and whether or not the added bacteria Can keep its dominance in the reactor were also studied to explore the mechanism of treating jiemycin wastewater by using the bacteria-added biological concoct oxidation process. By the separation and identification of aerobic microbial films from this system, 18 strains bacteria species in 11 genera were obtained. Their distribution of bscteria counts and the effectiveness of degrading organics show that after passing through a pilot operation the added bacteria still exist in the reactor and tube the dominant position, and the most dominant strain was identified to be in Aeromona. Both qualitative and quantitative analyses of the effluentS from pilot aerobic treatments were made to find the reasons for causing the remaining CODcr values.
