영문 초록

This study was carried out to suggest the measures and to understand the characteristics of water quality in Buerhatong river within yanbian area, China. Suspended solids appeared high in rainfall season, but BOD and COD appeared lower than suspended solids. The yearly average water quality of all location in this river was less than BOD 2mg/L, less than COD 5mg/L, and ammonia nitrogen was over than 1mg/L in 1997, and was suitable to the class III of environmental standard for the surface water. Because of domestic sewage and nightsoil exhausted at Yanji city without treatment system inflowed in this river. Synthetical pollution index was calculated for the assessment of water quality, had a tendency to increase near to the downstream. The highest pollution allocation rate is 44% as suspended solids. To reform the deteroriorated river, the sewage wastewater treatment plants will be constructed at Myoungwoal Jin and Yanji city by 2010, respectively. Then COD discharge loading produced in this watershed will be decreased by about 43% of total loading.
