부착성장 조류 제어를 위한 침전지 배수로의 재질개선에 관한 연구

Abstract

The objective of this study was to investigate the characteristics of adhesion and detachment of algae on various materials of drainage canal in the sedimentation basin.The influence of surface washability, surface roughness, phosphorous concentration was studied using stainless steel, cement block and ceramic panel. The algae attached content of cement block was higher than that of the ceramic coating panel. The attachment varied significantly with respect to exposure time and different materials. the attachment was higher on rough surface (cement block) when compared to smooth surfaces. The content of attached algae increased with increasing phosphorous concentration in water. The detachment efficient of algae was higher on ceramic panel.
