Abstract
A experimental study of sludge reduction in combination of the chemical ozone oxidation and biological method was made, with integrating the merits of SBF and sludge ozonation. The characteristics of sludge the ozonation and its influence on SBF performance were investigated. Two parallel SBF systems were run in order to compare ozone oxidation system and no ozone oxidation system. The results showed that ozonation was able to reduce markedly the sludge production rate of the system, with a sludge production rate of 0.043 kg/kg which was reduced by 76%, and no obvious influence was observed on nitration and organic removal, the outflow water quality of the system was also good.
