Abstract
염료공장의 고농도 유기성 폐수인 Toluidine Sulfonic Acid（TSA） 공정폐수의 희석처리도 실험과 TSA 공정폐수와 공장전체 폐수를 혼합한 종합폐수의 처리도 실험을 행하였다. TSA 공정폐수의 응집처리는 pH가 6.5일 때 황산알루미늄 300 ㎎/l 주입으로 약 40 %의 COD 제거 효과를 나타내었다. TSA 공정폐수와 종합폐수를 완전혼합 활성슬럿지 공법으로 처리한 결과, 폭기시간 86시간 이상, F/M비 0.074 ㎏BOD/㎏MLSS/day 이하에서 68 % 및 88 % 이상의 COD 및 BOD 제거율을 얻었으며, 이 실험조건에서 동력학적 계수, k, Ks, Y, Kd의 값은 각각 0.174-0.453 day-1, 68.8-152.6 ㎎/l, 0.445-0.653 및 0.0022-0.0075 day-1의 범위를 나타났다.
An laboratory-scale experiment was carried out to determine the characteristics and treatability of toluidine sulfonic acid （TSA） process wastewater and combined wastewater in a dye plant.
Chemical treatment with aluminium sulfate, 300 ㎎/l at pH 6.5 showed about 40 % COD removal efficiency. With a completely-mixed-activated-sludge （CMAS） unit, the removal efficiencies of BOD5 and COD were achieved more than 88 % and 66 %, respectively, at aeration time longer than 86 hours, that corresponded to the F/M ratio below 0.074 ㎏BOD/㎏MLSS/day.
Design parameters, such as k, Ks, Y and Kd applied to CMAS mathematical equations were found as the range of 0.174-0.452 day-1, 68.8-152.6 ㎎/l, 0.445-0.653 and 0.0022-0.0075 day-1, respectively.
