Effect of Specific Surface Area on Treating a Strong Waste by Aerobic Fixed-Film Process
비표면적을 달리하는 media를 이용하여 염료공장의 고농도 유기성 폐수를 호기성 생물막 공법으로 처리할시의 유기물질의 제거효율과 media에 부착되는 미생물의 양태를 조사하였다. 본 실험에 사용된 media 는 SARAN 4000D(media S)와 1000D(media B)로 비표면적이 각각 153m2/m3 과 307m2/m3이었다. 반응조내 media에 부착되는 평균 미생물농도는 media S의 경우가 9.5% 더 높았다. Media 표면적당 평균 미생물 부착량은 media S의 경우 48.2gSS/m2, media B의 경우 35.45gSS/m2으로 나타났으나 전체 미생물량으로는 거의 같았다.
This study was conducted to investigate the characteristics and treatment efficiency of aerobic fixed-film process with different specific surface area upon the variation of organic loading rate. The media used for this study was SARAN 4000D(media S) with specific surface area 153m2/m3, and 1000D(media B)with specific surface area 307m2/m3. The substrate used was a dye plant processing wastewater and the feed solution was diluted two fold or more as the feed solution. The influent COD concentration ranged about 1250 to 4080mg/l. Average biomass concentrations were 7316mg/l and 6683mg/l on the media B and S, respectively. The value of media B was about 9.5% higher than that of media S. Average amounts of attached biomass were 48.2gSS/m2 on the media S and 35.45gSS/m2 on the media B, but the total amount of accumulated biomass was nearly the same.
