     this paper offers an effective pretreatment method that can simultaneously achieve excess sludge reduction and bio-hydrogen production from sludge self-fermentation. batch tests demonstrated that the combinative use of ozone/ultrasound pretreatment had an advantage over the individual ozone and ultrasound pretreatments. the optimal condition (ozone dose of 0.158 g o3/g ds and ultrasound energy density of 1.423 w/ml) was recommended by response surface methodology. the maximum hydrogen yield was achieved at 9.28 ml h2/g ds under the optimal condition. according to the kinetic analysis, the highest hydrogen production rate (1.84 ml/h) was also obtained using combined pretreatment, which well fitted the predicted equation (the squared regression statistic was 0.9969). the disintegration degrees (dd) were limited to 19.57% and 46.10% in individual ozone and ultrasound pretreatments, while it reached up to 60.88% in combined pretreatment. the combined ozone/ultrasound pretreatment provides an ideal and environmental friendly solution to the problem of sludge disposal.
