Abstract

Water treatment system filled with Bio-stone Ball (BSB) have been developed for the purification of polluted water in many rivers and lakes. The real-scale plants of BSB water treatment system was constructed for field application test and water purification evaluation in Maewha reservoir. The average water purification efficiencies of BSB watertreatment system shows BOD 70.3% (47.2~97.4%), COD 45.3% (26.1~64.7%), TOC 19.2% (8.5~50.0%), SS 82.8% (73.1~92.7%), Chl-a 80.4% (57.2~91.8%), TN 23.2% (6.4~39.5%), and TP 51.8% (-1.1~80.1%). BSB water treatment system shows very high at 70~80% in the water purification efficiencies of BOD, Chl-a, and SS. The average of pollution loading reduction by installation of BSB treatment system shows 39.2% for COD and 16.8% for TP. The water quality improvement rates (%) of the Maewha reservoir shows TOC 14.5%, COD 14.5%, Chl-a 12.5% and TP 25.1%. The BSB watertreatment system can be applied to many agricultural reservoirs and major rivers to deal with serious water pollution issues.

본 연구에서는 유기성 오염도가 높은 국내 하천 및 호소의 수질정화를 위해 바이오스톤 볼 담체를 이용한 수처리 기술을 개발하였다. 바이오스톤 볼 수처리기술의 오염물질 제거효율 및 저수지 수질개선효과 등을 평가하기 위하여 경기도 시흥시에 위치한 매화저수지에 실증플랜트를 설치하였다. 바이오스톤 볼 수처리시스템의 오염물질 제거효율은 BOD 70.3%(47.2~97.4%), COD 45.3%(26.1~64.7%), TOC 19.2%(8.5~50.0%), SS 82.8%(73.1~92.7%), Chl-a 80.4%(57.2~91.8%), TN 23.2%(6.4~39.5%), TP 51.8%(-1.1~80.1%)로 나타나 BOD, SS, Chl-a에서 평균 70~80% 이상의 매우 높은 정화효율을 나타내었다. 바이오스톤 볼 수처리시스템을 저수지 평시 유입량 설계기준으로 설치하였을 경우의 유입 오염물질 저감량 및 저수지 수질개선효과를 산정하였다. 저감되는 COD 부하량은 13,658 kg으로 연간 39.2%가 저감되고, TP 부하량은 297 kg으로 연간 16.8%가 저감되는 것으로 나타났다. 저수지의 연간 수질개선효과는 TOC $5.3{\rightarrow}4.5mg/L$(14.5%), COD $7.9{\rightarrow}6.8mg/L$(14.5%), Chl-a $42.3{\rightarrow}37.0mg/m^3$(12.5%), T-P $0.201{\rightarrow}0.150mg/L$(25.1%)가 평균적으로 개선되는 것으로 나타났다. 바이오스톤 볼 수처리시스템은 유기성 오염도가 높은 국내 하천 및 호소의 유입수 오염물질 제거 및 수질정화를 위한 수처리 시설로서 현장적용성이 높을 것으로 판단된다.
