Summary:The invention discloses a residual sludge pretreatment device. The device comprises a closed square shell. A first anode plate, a second anode plate, a cathode, an air pipe internally provided with anultrasonic vibrator, a plurality of stirring blade heads and a filtering pipe are arranged in the shell. An air inlet pipe and a rectifier are connected to the top of the shell. The residual sludge is introduced into an inlet, air or oxygen is introduced into the air pipe, and sulfur dioxide is introduced into the air inlet pipe. According to the device disclosed by the invention, the combined action of multiple factors such as electrode discharge, electrode participation oxidation, catalyst catalytic oxidation, ultrasonic crushing and mechanical wall breaking is comprehensively utilized, sothat the structural damage to cell walls is greatly enhanced, the cracking degree and effect are enhanced, and the subsequent oxidation effect on organic pollutants is continuously and effectively carried out; part of water is
