우리나라에서 하천에 유입되는 유기물부하의 많은 부분을 차지하는 산업폐수를 대상으로 유기물 오염지표간의 상관성을 조사하였다. 기존 사용되고 있던 COD와 BOD를 현재 많은 국가에서 도입하고 있는 TOC와의 관계를 규명하였다. 업종별 업체별로 그 상관계수에는 큰 차이가 있었으며, 최고의 상관계수는 음식료품 생산업체의 방류수 중에 함유된 COD/BOD/TOC와의 관계에서 나타났다. 각각의 상관계수는 COD/BOD: 0.997, COD/TOC : 0.969, BOD/TOC: 0.990이었다. 상관계수가 낮은 경우도 많았으며, 동일업종이라 하더라도 상관도에는 일관성이 없었다. 그러므로 수질기준 책정 또는 하천수질 모니터링 등에 기존의 유기물질지표의 대체지표로써 TOC를 사용하는 것은 불가능할 것으로 사료된다. 그러나 이들의 상관도가 높은 방류수의 관리에 있어서는 유용하게 사용될 수 있으므로 이들 유기물질 인자간의 상관성을 검토하여 개별적으로 사용하여야 할 것이다. We investigated the relationship of the organic pollutant index in wastewater where the high percentages of an organic load to a water body was found. Measuring of TOC was to identify the relationship with COD and BOD which were used already. The correlation coefficient (r) of TOC/COD, BOD/COD and TOC/BOD were effected by the types of industry such as paper, textile, chemical, food and metal industries. In food industry it was found that the highest correlation coefficient (r) of TOC/COD, BOD/COD and TOC/BOD as 0.967, 0.969 and 0.990, respectively. There is low correlation coefficient in many cases. Hence it was impossible that the use of TOC for the water standard or monitoring instead of COD and BOD directly. However it can be used as alternative index to management a water process in the case of waste water where there was found high correlation coefficient of TOC/ COD, BOD/COD and TOC/BOD. It was sure that the water quality of river body can be protected if we use these the relationship among organic index.

The tele-monitoring system (TMS) refers to a system that monitors the emission state of pollutants on a 24-hour basis by online-connecting a remote water quality control center with automatic measurement devices attached to the discharging outlets of wastewater processing facilities and wastewater-producing businesses. The core of the TMS is the reliability of data from the continuous water monitoring equipment (CWME). The data reliability depends upon the accuracy and uniformity of the monitoring equipment as well as the representativeness of samples. The water sampling system is a major factor affecting the measuring results because it consists of a series of continuous sample collection processes from the effluent outlet to the CWME. Experiments were performed with a specially designed sampling system. The mixing characteristics of each sample in the designed system were investigated using three-dimensional computational analyses of fluid and tracer tests. In addition, the residence time distribution (RTD) and the dispersion number were analyzed. The results showed that the sampling system is applicable as a standard of performance test for sampling baths.
