The Keum river is one of the important river in Korea and has a drainage area of 9,873㎞² The Keum river is deepening pollution state due to development of the river city and construction of a industrial complex. The water quality of the Keum river come to eutrophication state and belong to ill grade of water quality standard.
The concentration BOD in liver is affected by the organic loading from a tributary and the algae biomass that largely happen to under eutrophication state, In the eutrophic water mass such as the Keum river. the autochthonous BOD was very important part for making a decision of water quality management. because it was accounted for making of the total BOD.
The purpose of this study was to survey the characteristics of water quality in summer and to estimate reaction coefficient. Also. we studied to correlationship between chlorophyll ,( and BOO(COD) for istimation of the autochthonous BOD. The correlationship between chlorophyll a and BOO(COD) were obtained through the culture experiment of phytoplankton in the laboratory. The results of this study may be summarized , as follows; The characteristics of water quality in summer were belong to Ⅲ~Ⅳ grade of water quality standard as BOD and nutritive condition is very high. The BOD. ammonia nitrogen and phosphate loadings in Miho stream which in flowing untreated sewage from Chungju city was occupied with 64.07%, 23.36%, 46.08%, respectively. Maximum nutrient uptake (Vmax) was 0.4400 μ M/hr as substrate of ammonia nitrogen. 0.1652μ M/hr as substrate' of phosphate, Maximum specific growth rate (μ max) was 1.2525 hr-¹ as substrate of ammonia nitrogen, 1.5177 hr-¹ as substrate of phosphate. The correlation coefficient bet ween chlorophyll a and BOD by the culture experiment were found to be 0.918~0.977and 0.942~0,947 in the case adding nutrient and no adding nutrient. respectively. The correlation coefficient between chlorophyll a and COO through the culture experiment were found to be 0.918-0.977 and 0.880~0.931 in the case adding nutrient and no adding nutrient, respectively. The autochthonous BOO(COD) was estimated to the relationship between BOD(COD) and chlorophyll a. The regression equation were found to be autochthonous BOD=(0.045~0.073) × chlorophyll a and autochthonous COD=(0.137~0.182)×chlorophyll a.
