Zusammenfassung:In this study, the improvement of the operation condition and the water quality in water treatment plant by operating information system(OIS) was evaluated for Ansan water treatment plant. The average flow rate of raw water in the year 2005(after constructing the OIS) appeared 15.6 % lower than that in the year 2004(before constructing the OIS). The mean value(12.37 NTU) of raw water turbidity in the year 2005 remained constant, or nearly so with that(12.06 NTU) in the year 2004. The average dosing rates of coagulant appeared 12.06 mg/L in the year 2005 which was higher than 10.31 mg/L in the year 2004. Furthermore, the average turbidity concentration of fresh water in the year 2005 appcared slightly better than that in the year 2004. From $COD_{Mn}$ and BOD concentration of raw water, the water quality in the year 2005 were better than those in the year 2004. The average concentration of $KMnO_4$ in the year 2004 and the year 2005 was 2.95 mg/L and 1.25 mg/L, respectively, and the average concentration of THMs in the year 2004 and the year 2005 appeared 0.038 mg/L and 0.025 mg/L, respectively. Therefore, the fresh water quality in the year 2005 was better than that in the year 2004. In this study, it is considered that the operation of Ansan water treatment plant may be optimized by OIS, and thus the OIS may be very useful method to improve the water quality. 본 연구에서는, 안산정수장에 구축된 수도시설 운영정보화 시스템에 의한 처리수질개선 등 정수장 효율개선효과를 평가하였다. 분석기간 동안의 안산정수장 생활용수 유입유량은 운영정보화 시스템이 구축되기 전인 2004년도보다 구축 후인 2005년도가 약 15.6% 감소한 것으로 나타났다. 원수의 평균탁도는 2005년 12.37 NTU, 2004년 12.06 NTU로 비슷한 값을 나타내었으나, 연평균 응집제의 주입농도는 2005년도가 12.06 mg/L으로 2004년(10.31 mg/L)보다 다소 높은 것으로 나타났고, 정수탁도는 약간 개선된 처리효율을 나타내었다. 원수의 $COD_{Mn}$ 및 BOD 등의 분석결과, 2004년보다 2005년의 원수수질이 개선된 것으로 판단할 수 있었다. 정수의 $KMnO_4$ 소비량은 2004년(2.95 mg/L)보다 2005년은 1.25 mg/L로써 그 양이 줄어들었고, THMs의 농도도 2004년(0.038 mg/L)보다 2005년 0.025 mg/L로써 다소 개선되었다. 본 연구결과, 약품주입 등 정수장 운영은 운영 정보화 시스템의 구축에 의해 보다 최적의 상태를 도모할 수 있으며, 이에 따라 수질개선효과도 있음을 판단할 수 있었다.
