9. The sludge dewatering treatment vehicle according to claim 8, wherein two triangular filter screens (35) are welded in two mounting holes, a circular slide hole is formed in the outer wall of one side of the fixing plate, the movable ring (36) is rotatably connected in the circular slide hole, each triangular pyramid (38) is welded on the inner wall of the circumference of the movable ring (36), and two L-shaped guide grooves (37) are formed in two sides of the bottom of the fixing plate.
10. A sludge dewatering treatment method of a sludge dewatering treatment vehicle is characterized by comprising the following steps:
s1: guiding the sludge into a stirring box (8) through a sludge pump, and stirring the sludge through a stirring mechanism (20);
s2: in the process, sludge is rapidly mixed into alum flocs through the liquid inlet pipe (18) into the stirring tank (8), the alum flocs are gathered and concentrated through gravity, and a large amount of filtrate is discharged into the guide flow tank (11) from a filter seam of the first filtrate membrane (22) and is guided into the filtrate chamber through the liquid guide pipe (12) on the guide flow tank (11);
s3: then, the sludge continues to enter the filter-pressing box (3) through the L-shaped conduit (6);
s4: then, a first motor (5) is started to drive a spiral shaft (23) to rotate, so that sludge is pushed to one side in a centralized manner, the rotating sludge can effectively drive a movable ring (36) to rotate in the pushing process, the sludge is sheared through a triangular pyramid (38) in the sludge to promote the loss of water in the sludge, and two triangular filter screens (35) on a fixing plate are used for filtering and deslagging the sludge;
s5: finally, the filtrate in the filter-pressing box (3) is guided into the filtrate chamber through a second filtrate membrane, and the dewatered sludge is guided into the sludge guide chamber through a sludge guide hole on one side of the fixed cover (15) and is guided out from a discharge hole (14) on one side of the sludge guide chamber.
