Abstract

We found that the Bacterium Burkholderia cepacia in livestock wastewater treatment plant was predominant species. We investigated the growth rate of this and treatment characteristics for organic matter and nitrogen removal in livestock wastewater using this microorganism. First, we cultured B. cepacia. And then, to conducted treatment for livestock wastewater by using B. cepacia., we changed C/N from 0.2~4.4. When we operated A and B process, changing F/M ratio from 1.2 to 4.4. In experiment of C/N variations, when C/N was 1.8, we found that the optimal condition for organic matter and nutrient removal effect was higher and the removal efficiency of $SCOD_{cr}$, $SBOD_5$,$NH_4-N$ was 78.4%, 95% and 74.8%. So, It is possible to treat the wastewater having the lower C/N contents such as livestock wastewater using this microorganism. In experiment of A and B process for livestock wastewater, we found that the removal efficiency of organic matter and nitrogen in operating mode of A process was higher than that of B process. Also, the optimal F/M operating A process was 0.013 and the removal efficiency of $SBOD_5$, $SCOD_{cr}$, TN and TP were 97%, 60%, 95% and 91%.
