Abstract

The possibility of the biological treatment of MBT wastewater generated from the vulcanization accelerator manufacturing process was investigated. MBT wastewater is not biodegradable because it hinders the activity of microorganisms, and approximately 10% of the total COD can be removed after a 7 day acclimation period. The optimal conditions of the MBT wastewater for the chemical pre-treatment was pH of 3.5 and the Fenton oxidation with the addition of $Fe^{3+}$ to the wastewater after agitation for 2 hours. The Fenton-treated MBT wastewater showed approximately 20% removal of COD when treated with the activated sludge process for the mixed paper wastewater and Fenton treated wastewater.

본 연구는 가황촉진제 제조공정에서 발생되는 MBT 폐수의 생물학적 처리가능성을 평가하였다. MBT 폐수는 미생물 활동을 저하시키기 때문에 생물학적으로 처리가 불가능하였지만, 7일의 순응기간을 거쳐 약 10%의 COD가 제거되었다. MBT 폐수의 화학적 전처리를 위한 최적조건은 pH 3.5, 2시간동안 교반 후 $Fe^{3+}$를 주입하여 펜톤산화를 한 경우였다. 또한, 펜톤처리 된 MBT 폐수를 제지폐수와 혼합하여 활성슬러지공정에서 처리했을 경우 MBT 폐수의 COD가 약 20% 제거되었다.
