| Abstract |
The characteristics of swine wastewater are different according to the type of pigsties, method of removing swine wastewater, quantity of washings, etc. It is difficult to get granular which is required for UASB because swine wastewater consists of high concentrations of solid and NH₃. A purpose of this study is to test the applicability and solve the problems happened in operating UASB in the field. Non-granular microorganisms acclimated to the substrate of swine wastewater, granular microorganisms produced in the brewing wastewater and their mixture were seeded respectively. When diluted wastewater($lt; TS 2%) was injected into the reactors, the reactor which was seeded with the mixture showed the highest COD removal rate. When raw wastewater of slurry type was injected into the reactors, all reactors showed the rise of sludge layer regardless of HRT and type of seedings. |
