Abstract: A kitchen waste wastewater treatment equipment includes a reaction kettle, a discharging mechanism and a pressurizing mechanism. In the process of high-temperature and high-pressure thermal hydrolysis of wastewater in the present disclosure, the pressurizing disk in the pressurizing mechanism continuously moves downwards in a vacuum state in the reaction kettle, reducing the volume in the reaction kettle and thus increasing the pressure. The secondary pressurization of wastewater is achieved while using heating for high-temperature and high-pressure, and the high-temperature and high-pressure environment greatly improves the reaction rate of thermal hydrolysis. The thermal hydrolysis reaction also generates gas for further pressurization, which greatly improves the treatment efficiency of wastewater. Moreover, the pressurizing mechanism and the exhaust annular groove can separate the gas generated after thermal hydrolysis.
