K leather industry wastewater treatment plant(advanced treatment process) was selected to evaluate statistical analysis. 95% reliability of effluent concentration were 106.8㎎/ℓ of COD(Mn), 86㎎/ℓ of SS, 72.04㎎/ℓ of TN, 0.98 ㎎/ℓ of ABS, 1.8㎎/ℓ of n-Hexane, 9.7 ㎎/ℓ of BOD5 and 0.11 ㎎/ℓ of Cr. ㎎ℓ Coefficients of reliability were 0.63 and 0.03 in terms of COD(Mn) and BOD5. The range of CV(coefficient of variation) were between 0.18 and 2.49. Also, COR(coefficient of reliability) were between 0.03(BOD5) ~0.63(CODmn) and 0.43 in terms of T-N. Z(1-α) (Normalized Percentiles) value were 55.7 and 2.25 in terms of BOD and T-N.

K leather industry wastewater treatment plant(advanced treatment process) was selected to evaluate effluent quality and pollutants removal efficiencies. BOD5 concentration of effluent was 3.95㎎/ℓ and its removal efficiency was 99.8%. Also, most of other pollutants removal efficiencies were over 90% as well. And 95% reliability of effluent concentration were 106.8㎎/ℓ of CODmn, 86㎎/ℓ of SS, 72.04㎎/ℓ of TN, greater than the effluent limitation(60㎎/ℓ), 0.98㎎/ℓ of ABS, 1.8㎎/ℓ of n-Hexane, 9.7㎎/ℓ of BOD5 and 0.11㎎/ℓ of Cr.

본 연구는 하천수질관리에 대한 GIS의 적용 가능성을 타진하기 위해 안양천을 시범지역으로 선택하여 수행되었다. 본 논문은 GIS 기법을 하천수질문제에 적용함으로써 얻게 되는 장점에 관하여 논하였다. GIS 기법은 오염원의 특성을 파악하고 그 오염유발의 원인과 연계시킴으로써 오염문제에 대처할 수 있는 일련의 실행계획 수립을 가능케 하며 하천의 수질을 지도에 근거하여 평가할 수 있다. 또한, GIS는 예견치 않은 오염물 유출 사고가 발생할 경우 하천수질관리를 위한 적절한 대안을 수립하는데 도움을 줄 수 있다. GIS 기법을 적용하기 위해서는 지형 및 오염원에 대한 광범위한 정보가 필요하다. This investigation is performed to explore the potentiality of GIS(geographic information system) application to water quality management in streams with the Anyang Creek being selected as a demonstration site. The paper discusses benefits incurred from GIS technique as may be applied to stream quality problems. Scientifical characterization of the pollutional sources, linking them with causes and creating a series of action plans to cope with the problems may help decision makers with extensive mapping-based assessment of stream water quality. It also helps develop alternative strategies for managing water quality in streams in case of emergency spills. GIS application requires extensive information about area geography and pollutional sources.
