Ozone treatment on sludge reduction was studied. And the factors of the reaction processes were discussed. The results showed that the method could reduce the sludge efficiently. With the increase of gas flow and reaction time, the sludge removal rate increased gradually. When the gas flow was 2.00 L/min, and the reaction time was 60 minutes, the activated sludge removal rate was about 61.1%. The COD and NH4+-N value increased after the reaction, and the mineralization increased also. Furthermore, the biodegradability of the liquid after ozone treatment was improved, which was beneficial to the sewage treatment process.
