[Impact of hydrothermal process on the dewaterability and degrease performance of restaurant garbage].

In order to ameliorate the dewaterability and degrease performance of restaurant garbage, and to improve the treatment effect, a complete trail series with 2 factors on 5 levels was implemented. The 2 factors were temperature and retention time respectively as the main influencing factors of hydrothermal process. By means of analyzing the variation of the resistance, dewatering rate and floatable oil content of the treated restaurant garbage, and constructing the solid grease extracting kinetics, the mechanism of impact of hydrothermal process on the dewaterability and degrease performance of restaurant garbage was studied.
