Abstract
The purposes of this research were constructed the database, based on graphing the present water pollution in Han-river due to livestock wastewater(LSW). The LSW was below 1% in respect to quantity but about 7% in respect to pollutants loading in overall Han-river. The ratio of untreated LSW is 18% to 28%, which was higher compared to the municipal and industrial wastewater. In other words, LSW was about 0.05 times of municipal wastewater in respects to quantity but 2 times in respect to the ratio of untreated wastewater. So, it was necessary for treating LSW. The pollutants loading due to livestock wastewater of the South Han-river, North Han-river and main stream were 19.7%, 19.4% and 4.0%, respectively. This was about 7% in overall Han-river. We separated the Han-river into upper, mid and down stream. As a result, we found that the livestock wastewater is the main water pollution source of upper Han-river.
