when the two positioning columns (45) slide away from each other, negative pressure is formed in the pressure pipe (431) so that water in the water inlet pipe flows into the pressure pipe (431).

7. The solid waste treatment system of claim 6,

a hose groove (210) is formed in the upper end face of each first fixing plate (21), a hose is arranged in each hose groove (210), and the hose is communicated with the pressure pipe (431); wherein

The pressure tube (431) is pressed to inject water into the hose to expand the hose.

8. A method of operating a stationary waste treatment system, comprising a solid waste treatment system as claimed in claim 7:

the material enters the equipment body (1) from the feeding port (10), the driving motor (11) is started to work, the driving motor (11) drives the two adjusting plates (42) to move in a reciprocating mode in a separating mode or in an opposite mode, the two adjusting plates (42) synchronously drive the two positioning columns (45) to move in an opposite mode or in an opposite mode so as to push the pushing plate (43) to slide in a reciprocating mode in the horizontal direction, and therefore the second linear rack (33) is driven to slide in a reciprocating mode to crush the material; when the two positioning columns (45) move towards or away from each other, the pressure pipe (431) is synchronously pressed, so that water in the pressure pipe (431) is sprayed to the second linear rack (33) through the water spraying holes (241); when the pressure pipe (431) is pressed, water can be synchronously injected into the hose so as to shake off the material on the upper end of the first fixing plate (21); when the rotating column (22) is rotated to the vertical state of the first fixing plate (21), the distance between the second linear rack (33) and the side wall of the first fixing plate (21) can be adjusted to enlarge the crushing grain diameter of the material.
