Low temperature carbonization waste has high ammonia apart from phenolics. Ammonia removal has been reported to be poor when the waste is subjected to activated sludge process. The present 3tudy was hence directed to find the factors responsible for the poor ammonia removal. The wastewater, after the removal of phenolics with and after the elimination of colour causing compounds was tested for nitrification both at batch scale and in continuously fed completely mixed activated sludge system. Further, the effect of alkalinity on nitrification was also studied. The results indicated that ammonia removal efficiency of 72 and 90 per cent in the case of coloured and decolourized effluent respectively could be achieved at optimum HRT of 48 hours. Further, it has been observed that the colouring compounds like polymerized phenols and hydantions affect nitrification in general and nitratification in particular. External supplementation of carbonate alkalinity was found to be essential for improved nitrification. |
