|
To develop the treatment process of swine wastewater using Rhodopseudomonas palustris KK14 with high utilizable ability of organic acids, some operating conditions were investigated and optimized in flask-scale and laboratory-scale reactors. The optimal operating conditions in photosynthetic bacteria (PSB) reactor of semi-continuous type were obtained at HRT 6 day, 5% (v/v/day) seeding rate of PSB sludge and 10% (v/v/day) returning rate of PSB return sludge. Under the above operating condition, COD level of the wastewater (initial COD: 10 g/ℓ) was reduced to about 1-7 g/ℓ after 4 days treatment and MLSS was held constant at 4∼5 g per liter. In laboratory-scale process consisted of 5.2ℓ anaearobic digestion reactor and 15ℓ PSB reactor, the total removal rates of COD and BOD were increased to 95% and 96% by the continuous operation for 5.36 days, respectively, showing 3 Kg COD/㎥/day COD loading rate and 1.1 Kg COLA/Kg MLSS/day sludge loading rake in PSB reactor. The offensive odor was considerably removed through the treatment process of swine wastewater.
