Abstract: With the starch,cellulose as model compound and H2O2 as oxidant，an experiment was carried out to study the influence of temperature，time and oxygen amount on organic acid transform rate of kitchen wastes（rice,cabbage）during subcritical water oxidation treatment．The rates of transformation of the carbon to the organic acid（formic acid,acetic acid） were used as main indexes to evaluate the disposal effect in order to decide the optimum operation parameters．The results showed that for rice， temperature 280℃，treatment time 1～1.5 min，oxygen amount 70%～100%；for cabbage，temperature 280～300℃，treatment time 1～2 min，oxygen amount 70%～100%．
