摘要：This paper presents the treatment of water effluent of alcohol distillery plant (Som Distillery Pvt. Ltd., Raisen Road, Bhopal, M.P.) by catalytic thermolysis.The effluents were thermally preheated at atmospheric pressure and 80-100oC in a vertical condenser equipped atmospheric glass reactor (AGR). The effluent charge along with the catalyst was heated to the desired temperature with constant magnetic stirring and the liquid samples were withdrawn at definite time intervals for analysis. The liquid sample was filtered and the filtrate was centrifuged and analyzed for COD by standard dichromate reflux method. The effect of initial pH and the duration of treatment with each catalyst (at a concentration of 3 kg m-3) were investigated. Both homogeneous CuSO4 and FeCl3and heterogeneous (CuO, ZnO, MnO) composite oxides were used for the assessment of effectiveness of catalytic thermolysis in enhancing the removal of COD from both the DSW and BDE.
