Abstract

The objective of this paper is to estimate the pollutant load based on event mear concentrations(EMC) in industrial complex. Eight sub-basins in the Chongju industrial complex were selected for sampling and study with different characteristics during the period from June 1997 to August 1998. During the storm events, measured EMC ranges of $BOD_5$, COD, SS, TKN, TP, HEM, $NO_3-N$, $PO_4-P$, Cr, Pb, Cu and Fe in the industrial complex watersheds were 11~176mg/L, 40~502mg/L, 23~633mg/L, 104~20.9mg/L, 0.22~7.51mg/L, 12.7~548.7mg/L, 0.06~2.66mg/L, 0.12~3.39mg/L, 0.01~0.50mg/L. 0.02~0.42mg/L, 0.01~0.15mg/L and 1.29~11.51mg/L respectively. And the calculated annual average pollutant unit loadings of $BOD_5$ COD, SS, TKN, $NO_3-N$, $PO_4-P$, TP, HEM, Cr, Pb, Cu and Fe were 374.4kg/ha/yr 924.1kg/ha/yr, 983.6kg/ha/yr, 48.8kg/ha/yr, 8.1kg/ha/yr, 9.7kg/ha/yr, 17.8kg/ha/yr 943.0kg/ha/yr, 0.7kg/ha/yr, 0.9kg/ha/yr, 0.3kg/ha/yr and 28.9kg/ha/yr, respectively.

본 연구의 목적은 산업단지의 개별공장 및 유사한 공장이 밀집된 유역을 대상으로 유출수를 분석하여 유량가중평균농도를 산정하고, 이를 기초로 하여 업종별 유출오염부하 원단위를 산정하는데 있다. 1997년 6월부터 1998년 8월까지 청주산업단지를 대상으로 유량 및 수질을 조사하였다. 분석결과를 기초로 산정된 조사지점별 EMC 범위는 $BOD_5$, COD, SS, TKN, TP, HEM, $NO_3-N$, $PO_4-P$, Cr, Pb, Cu, Fe에 대해 각각 11~176mg/L, 40~502mg/L, 23~633mg/L, 1.04~20.9mg/L, 0.22~7.51mg/L, 12.7~548.7mg/L, 0.06~2.66mg/L, 0.12~3.39mg/L, 0.01~0.50mg/L, 0.02~0.42mg/L, 0.01~0.15mg/L, 1.29~11.51mg/L로 산정되었다. 또한, 강우시 산업단지에서 유출하는 년평균 오염부하 원단위는 $BOD_5$, COD, SS, TKN, $NO_3-N$, $PO_4-P$, TP, HEM, Cr, Pb, Cu, Fe에 대해 각각 374.4 kg/ha/yr, 924.1kg/ha/yr, 983.6kg/ha/yr, 48.8kg/ha/yr, 8.1kg/ha/yr, 9.7kg/ha/yr, 17.8kg/ha/yr, 943.0kg/ha/yr, 0.7kg/ha/yr, 0.9kg/ha/yr, 0.3kg/ha/yr, 28.9kg/ha/yr로 산정되었다.
