摘 要:正With the increasing demand for high efficiency and safety sludge treatment technology,an advanced sludge treatment process combining hydrogen peroxide and ozone was *** impacts of different pH value,ratio of hydrogen peroxide to ozone and the original sludge concentration on sludge disintegration were *** on the analysis of different parameters,soluble total organic carbon and particle chemical oxygen demand were selected as the indicator of sludge *** a result,it can be concluded that the combination of hydrogen peroxide and ozone process had a good performance when the molar ratio of hydrogen peroxide to ozone was 1.2 and the pH value was at the range of 6~*** increase of sludge initial concentration was benefit for sludge *** this study,the identical initial concentration of sludge was 9,850~20,000mg/*** addition,experimental results also indicated that the hydrolysis of sludge could be used as an alternative carbon source for nitrogen removal and the average rate of COD consumption of sludge supernatants was 7.67mgCOD/gMLSS·h.
